Spacetime
In physics, spacetime is any mathematical model that combines space and time into a single interwoven continuum. The spacetime of our universe has historically been interpreted from a Euclidean space perspective, which regards space as consisting of three dimensions, and time as consisting of one dimension, the "fourth dimension". By combining space and time into a single manifold called Minkowski space, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.
Explanation
In non-relativistic classical mechanics, the use of Euclidean space instead of spacetime is appropriate, because time is treated as universal with a constant rate of passage that is independent of the state of motion of an observer. In relativistic contexts, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow the passage of time for an object as seen by an observer outside the field.

Space / Time
"Space" and "Time" are two mini-episodes of the British science fiction television series Doctor Who. They were broadcast on 18 March 2011 as part of BBC One's Red Nose Day telethon for the charity Comic Relief. The two mini-episodes were written by the programme's head writer Steven Moffat and directed by Richard Senior.
The episodes form a two-part story, set entirely within the TARDIS, starring Matt Smith as The Doctor, and Karen Gillan and Arthur Darvill as married couple Amy Pond and Rory Williams. Rory, helping the Doctor work on the TARDIS, looks up the glass floor surrounding the console and becomes distracted by Amy's short skirt, causing him to drop the thermal couplings he was holding. This causes the three to be stuck in a "space loop" where the TARDIS materialises inside of the TARDIS.
"Space" and "Time" were filmed in two days alongside the sixth series DVD Night and the Doctor extras "Bad Night" and "Good Night". The episodes are intended to show what life aboard the TARDIS would be like. Several editing techniques and doubles were used for the various shots where there were more than one of the same character on the screen. The mini-episodes received mixed reviews; some scenes were thought to be funny, but other jokes were criticised for relying on sexist humour. "Space" and "Time" were later released on the DVD and Blu-ray sets of the sixth series.

Continuum (TV series)
Continuum is a Canadian science fiction series created by Simon Barry and produced by Reunion Pictures Inc., Boy Meets Girl Film Company, and GK-TV.
The series centers on the conflict between a group of terrorists from the year 2077 who time travel to Vancouver, BC, in 2012, and a police officer who unintentionally accompanies them. In spite of being many years early, the terrorist group decides to continue its violent campaign to stop corporations of the future from replacing governments, while the police officer endeavours to stop them without revealing to everyone that she and the terrorists are from the future. The show premiered on Showcase on May 27, 2012 with 10 episodes, and concluded after four seasons and 42 episodes on October 9, 2015.
Prelude
Episodes from seasons 1 and 2 begin with the plot of the show narrated by a voiceover from the point of view of Kiera Cameron.
In Season 3, the narration was replaced by a new sequence that contains a CGI version of the time travel device, scenes from previous seasons, and cast credits, before finishing with Kiera Cameron (Rachel Nichols) holding the device, followed by the title card.

Tadd Dameron
Tadley Ewing Peake "Tadd" Dameron (February 21, 1917 – March 8, 1965) was an American jazz composer, arranger and pianist. Saxophonist Dexter Gordon called him the "romanticist" of the bop movement, while reviewer Scott Yanow wrote that Dameron was the "definitive arranger/composer of the bop era".
Biography
Born in Cleveland, Ohio, Dameron was the most influential arranger of the bebop era, but also wrote charts for swing and hard bop players. The bands he arranged for included those of Count Basie, Artie Shaw, Jimmie Lunceford, Dizzy Gillespie, Billy Eckstine, and Sarah Vaughan. He and lyricist Carl Sigman wrote "If You Could See Me Now" for Sarah Vaughan and it became one of her first signature songs. According to the composer, his greatest influences were George Gershwin and Duke Ellington.
In the late 1940s, Dameron wrote arrangements for Gillespie's big band, who gave the première of his large-scale orchestral piece Soulphony in Three Hearts at Carnegie Hall in 1948. Also in 1948, Dameron led his own group in New York, which included Fats Navarro; the following year Dameron was at the Paris Jazz Festival with Miles Davis. From 1961 he scored for recordings by Milt Jackson, Sonny Stitt, and Blue Mitchell.

Continuum (sculpture)
Continuum is a public artwork by American sculptor Charles O. Perry located in front of the National Air and Space Museum in Washington, DC, United States.
Description
The sculpture is a large swirling abstract that consists of 8 bronze pieces painted black and placed on a pole. It moves freely.
Information
According to the artist the piece "began as an exploration of the Möbius strip, a product of pure mathematics formed by joining two ends of a strip of paper after giving one end a 180 degree twist, thus creating only one edge. The center of the bronze sculpture symbolizes a black hole, while the edge shows the flow of matter through the center from positive to negative space and back again in a continuum."
A similar sculpture exists, by Perry, called "Continuum II" which is installed Marina Square in Singapore and dates to 1986.
Condition
In July 2010 the piece underwent restoration to remove a green patina that formed on the sculpture. Perry's vision was for the piece to remain black. The piece was removed from its location to the west end of the building where it underwent its conservation by a contractor. The granite base that holds the 7,000 pound sculpture was also repaired.

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

Trompe le Monde
Trompe le Monde is the fourth studio album by the American alternative rock band Pixies, released in 1991 on the English independent record label 4AD in the United Kingdom and by Elektra Records in the United States. After the surf-pop of Bossanova, the album saw a return to the abrasive sound of the band's early albums.
Critical reception
The album was described by Michael Bonner, writing in Lime Lizard, as "one of the best albums that you may very well ever hear" and "a strong contender for best album of the 20th century".AllMusic writer Heather Phares noted the reduced role of Kim Deal, calling it "essentially Black Francis' solo debut".
Content
The album name comes from the title of the first track, "Trompe le Monde", a French phrase meaning "Fool the World". Unlike previous albums, the title of the album comes from the name of a song (rather than a song lyric), and is a play on the French phrase "trompe l'oeil"—a painting technique in which the painter fools the viewer into thinking objects presented are real.

What Exactly is Spacetime? Explained in Ridiculously Simple Words
Spacetime, as a concept, is related to a space that consists of 4 dimensions instead of the regular 3-dimensional space. As early as 1905, Einstein proposed a now widely popular theory that the speed of light is independent of the motion of all observers, and that space and time are interconnected in a single continuum. This theory, which is now a cornerstone of modern and quantum physics, is known as Einstein’s special theory of relativity. Einstein's proposed idea of a single continuum where space and time are interwoven is what people call “space-time”. According to this theory, time—which has traditionally been considered an independent entity according to the principles of classical physics—is affected when a body moves through space. This happens because, according to the theory, tim...

How does the curvature of spacetime create gravity?
In 1919, Arthur Eddington led an expedition to observe a total solar eclipse, confirming that light passing near the Sun is deflected due to its gravity. This observation supported Einstein's theory of general relativity, which differs from Newton's laws by predicting that massive objects warp spacetime, affecting the path of light. Einstein resolved a paradox wherein photons traveling different distances (AB vs. CD) near a massive object like the Sun reach their destination simultaneously. According to special relativity, light's speed is constant, so photons traveling a shorter path (CD) should take less time. However, in general relativity, the presence of a massive object causes time to slow down, an effect called gravitational time dilation. To visualize this, imagine spacetime as a...

Space is expanding evenly everywhere, but if you rewind that expansion you find that all of space was once compacted in an infinitesimal point of infinite density—the singularity at the beginning of time. The expansion of the universe from this point is called the Big Bang. We like to tell this story because it's the correct conclusion from the description of an expanding universe that followed Einstein's general theory of relativity back in the 19-teens. But since then we've learned so much more since then. Does our modern understanding of the un...

Time Travel: Exploring Paradoxes, Possibilities, and Scientific Frontiers #timeTravel #spaceTime
Time travel has fascinated humanity for generations, intertwining scientific theories and imaginative storytelling. From Einstein's groundbreaking theory of relativity to the speculative concept of wormholes, this captivating topic invites questions about the nature of time and our place within it. Einstein's theory of relativity introduced the idea that time is not a fixed constant but a flexible dimension interconnected with space, forming what we know as space-time. This revolutionary concept suggests that under certain conditions, such as traveling at nearly the speed of light or being near massive objects, time can stretch or contract. This phenomenon, known as time dilation, offers a theoretical foundation for moving through time, albeit with practical limitations that challenge our...

SUMMARY
What is Spacetime? Are space and time the same thing? Space was thought to be nothing, an empty void with no matter in it. In 1908, Hermann Minkowski postulated that time could be thought of as a 4th dimension along with the three dimensions of space. Einstein later showed that this spacetime is a kind of geometry that can bend, affecting the trajectory and passage of time for objects. How can space and time be part of the same canvas? Space is measured in meters, while time is measured in seconds. How are the two interchangeable?
The definition of spacetime is the set of points in space and time, located with 4 numbers. This would be the location in 3 dimensional space and a time. You can also call these events.
In ordinary Euclidean space, the distance between two point A and B is fairly simple to figure out. The straight line between them is the shortest path. And it’s obvious also that any other path, from A to B will be longer.
If we change one of the coordinates to time, the math that we need is not based on Euclidean geometry, but Minkowskian geometry (or Minkowski Geometry). The straight line between A and B does not represent distance but time elapsed between two events. A straight line represents traveling at a constant velocity between the two events, and is the MAXIMUM duration. So for example, in spacetime, if you took a curved path from event A to event B, or a zig zag path, then the elapsed time would be lower compared to the straight line between A and B, because you will have traveled more in space than in time.
Einstein showed that there is no such thing as absolute time, and so that’s why we have a new formulation. But how do you add time and distance together, since the units are completely different? The key is that there in important conversion factor between time and space, that allows us to convert one to the other. And that conversion factor is, the maximum speed limit of the universe, that is, as far as we know, is the speed of light. The speed of light is the key to uniting space and time. We call this maximum speed “c” in physics.
And c is 299,792,458 meters per second. As you know speed is distance over time. If we multiply this speed by time, we get a distance. So now we can convert time in the same equation to distance – distance = c*t. Thus, the equation works by using this conversion factor.
This formulation for a 2 dimensional spacetime can be extended to the real 4 dimensional spacetime we live in. And that 4 dimensional geometry is the foundation for understanding General Relativity, with the addition that this spacetime is no longer flat, but can curve and contort. So the math gets complicated in General Relativity. The consequence of a curving spacetime is that this results in gravity.
Why do we have only 3 dimensions, why not more? And why not more than one time dimension? First, large spatial dimensions probably don’t exist because we would have detected them if they did. And more than one dimension of time could result in closed time-like loops, in other words it would allow travel to the past. This is considered an impossibility because it would break causality.
More than 3 spatial dimensions would also likely have fatal consequences. In 1920 Paul Ehrenfest showed that our orbit around the sun would be impossible if we had an additional spatial dimension. Other problems have also been identified, for example the orbit of the electron in atoms would become unstable.

If we had fewer spatial dimensions, then spacetime would be too simple for life. For example if we had only one spatial dimension, then orbits could not form. Two dimension would also probably be too simple to result in life.

There are cosmic events so powerful that they leave permanent marks on the fabric of the universe itself. Imagine two colossal black holes spiraling into each other, yes they send ripples in the fabric of spacetime—gravitational waves that we’ve only recently learned to sense. Ripples pass, leaving the pond … or the universe … unchanged when they’re gone. But ripples aren’t the only type of wave. There’s another type of wave that leaves a permanent mark—a memory etched in the fabric of the universe. They’re akin to gravitational tsunamis, and we’re on the verge of being able to detect them.

In 1919, Arthur Eddington led an expedition to observe a total solar eclipse, confirming that light passing near the Sun is deflected due to its gravity. This observation supported Einstein's theory of general relativity, which differs from Newton's laws by predicting that massive objects warp spacetime, affecting the path of light.
Einstein resolved a paradox wherein photons traveling different distances (AB vs. CD) near a massive object like the Sun reach their destination simultaneously. According to special relativity, light's speed is constant, so photons traveling a shorter path (CD) should take less time. However, in general relativity, the presence of a massive object causes time to slow down, an effect called gravitational time dilation.
To visualize this, imagine spacetime as a cylinder that, when influenced by a massive object, flares into a cone. Clocks lower in the gravitational field (closer to the cone's wide base) tick slower than those higher up, explaining why time passes differently at different altitudes. This effect has been experimentally confirmed, such as with atomic clocks on airplanes running faster than those on the ground.
Gravitational time dilation can be visualized by imagining two ants, one higher (A) and one lower (B) on the cone. Both move through spacetime at the same speed, but B's clock ticks slower due to the cone's shape. Thus, B ages slower than A.
This curvature of spacetime not only affects the flow of time but also creates gravity. Objects naturally follow the curved paths in spacetime, leading them to fall towards massive bodies. A stationary object's path in curved spacetime slopes toward the massive body, causing it to fall, illustrating that gravity is the manifestation of curved spacetime geometry. This explains why an object falls faster as it moves closer to a massive body and why, hypothetically, an object falling infinitely would reach the speed of light due to the extreme curvature of spacetime.

Here’s the story we like to tell about the beginning of the universe. Space is expanding evenly everywhere, but if you rewind that expansion you find that all of space was once compacted in an infinitesimal point of infinite density—the singularity at the beginning of time. The expansion of the universe from this point is called the Big Bang. We like to tell this story because it's the correct conclusion from the description of an expanding universe that followed Einstein's general theory of relativity back in the 19-teens. But since then we've learned so much more since then. Does our modern understanding of the universe still insist on a point-like Big Bang? Recent work actually gives us a way to avoid the beginning of time.

Time travel has fascinated humanity for generations, intertwining scientific theories and imaginative storytelling. From Einstein's groundbreaking theory of relativity to the speculative concept of wormholes, this captivating topic invites questions about the nature of time and our place within it.
Einstein's theory of relativity introduced the idea that time is not a fixed constant but a flexible dimension interconnected with space, forming what we know as space-time. This revolutionary concept suggests that under certain conditions, such as traveling at nearly the speed of light or being near massive objects, time can stretch or contract. This phenomenon, known as time dilation, offers a theoretical foundation for moving through time, albeit with practical limitations that challenge our current understanding of physics.
Among these challenges are the immense energy requirements and the need for exotic materials like negative energy. Scientists speculate that such materials might stabilize space-time distortions or even sustain wormholes, theoretical tunnels connecting distant points in space and time. While intriguing, these ideas remain speculative and unproven, existing more in the realm of theoretical physics than applied science.
Equally compelling are the time travel paradoxes that arise when altering the past. The famous grandfather paradox questions whether changing past events could disrupt the causality that led to the traveler's existence. Solutions to such paradoxes range from the speculative notion of alternate universes to the idea that time may be self-consistent, with past events unchangeable.
Time travel also thrives in the realm of science fiction, inspiring countless stories and novels that explore its possibilities and ethical implications. Iconic works like Frank Herbert’s Dune, Kim Stanley Robinson's Red Mars series, and Octavia Butler's Kindred bring imaginative depth to the topic. Theories of space-time manipulation, causality, and futuristic technology are woven into tales that reflect humanity’s curiosity and creativity.
Recent books, including Liu Cixin’s Three-Body Problem and Ted Chiang's Stories of Your Life and Others, continue to push the boundaries of sci-fi novels, offering fresh perspectives on time travel and space-time theories. Audiobook adaptations and new releases, such as the Foundation series by Apple, make these concepts accessible to diverse audiences, showcasing the intersection of science, philosophy, and narrative.
Exploring time travel not only deepens our understanding of theoretical physics but also inspires profound questions about the universe.

https://wn.com/Time_Travel_Exploring_Paradoxes,_Possibilities,_And_Scientific_Frontiers_Timetravel_Spacetime
Time travel has fascinated humanity for generations, intertwining scientific theories and imaginative storytelling. From Einstein's groundbreaking theory of relativity to the speculative concept of wormholes, this captivating topic invites questions about the nature of time and our place within it.
Einstein's theory of relativity introduced the idea that time is not a fixed constant but a flexible dimension interconnected with space, forming what we know as space-time. This revolutionary concept suggests that under certain conditions, such as traveling at nearly the speed of light or being near massive objects, time can stretch or contract. This phenomenon, known as time dilation, offers a theoretical foundation for moving through time, albeit with practical limitations that challenge our current understanding of physics.
Among these challenges are the immense energy requirements and the need for exotic materials like negative energy. Scientists speculate that such materials might stabilize space-time distortions or even sustain wormholes, theoretical tunnels connecting distant points in space and time. While intriguing, these ideas remain speculative and unproven, existing more in the realm of theoretical physics than applied science.
Equally compelling are the time travel paradoxes that arise when altering the past. The famous grandfather paradox questions whether changing past events could disrupt the causality that led to the traveler's existence. Solutions to such paradoxes range from the speculative notion of alternate universes to the idea that time may be self-consistent, with past events unchangeable.
Time travel also thrives in the realm of science fiction, inspiring countless stories and novels that explore its possibilities and ethical implications. Iconic works like Frank Herbert’s Dune, Kim Stanley Robinson's Red Mars series, and Octavia Butler's Kindred bring imaginative depth to the topic. Theories of space-time manipulation, causality, and futuristic technology are woven into tales that reflect humanity’s curiosity and creativity.
Recent books, including Liu Cixin’s Three-Body Problem and Ted Chiang's Stories of Your Life and Others, continue to push the boundaries of sci-fi novels, offering fresh perspectives on time travel and space-time theories. Audiobook adaptations and new releases, such as the Foundation series by Apple, make these concepts accessible to diverse audiences, showcasing the intersection of science, philosophy, and narrative.
Exploring time travel not only deepens our understanding of theoretical physics but also inspires profound questions about the universe. Whether through best sci-fi books or groundbreaking research, the journey toward uncovering the truth behind time travel continues to captivate and challenge humanity.

Time Dilation - Einstein's Theory Of Relativity Explained!
Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time dilation. But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation...

But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation of time dilation and Einstein’s theory of relativity and also explain how time slows down in a moving vehicle!

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space Time as he discusses Newton and Einstein's dispute over inertial frames of reference. Is Einstein's theory inconsistent? Is gravity even a force??? Check out the episode to find out!

You’ve probably known OF E=mc² since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc² explained to you properly? Mass equalling energy is mostly true, but E=mc² actually describes a much more interesting, and frankly mind-blowing aspect of reality that likely wasn’t covered in your high school physics class. Join Gabe on this week’s episode of PBS Space Time he discusses THE TRUE MEANING OF E=mc²

How do we study nothing? An empty jar still contains something: molecules of air and a bath of infrared light from its warm environment. But what if we suck out every last molecule of air, chill the jar to absolute zero, and shield it from all external radiation? The jar would contain only empty space, but it turns out that empty space is far from nothing.

The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is, for the most part, nicely described with a constant density of dark energy – the same amount of this stuff in every block of space. Which means if you increase the volume you increase the overall amount of dark energy – hence accelerating expansion. Mathematically we describe a constant energy density with the cosmological constant in the equations of Einstein’s general theory of relativity. But what if dark energy is NOT constant? What if the energy density in each patch of space increases over time? In that case, the acceleration itself could be … accelerating. That would be bad.

Spacetime, as a concept, is related to a space that consists of 4 dimensions instead of the regular 3-dimensional space. As early as 1905, Einstein proposed a now widely popular theory that the speed of light is independent of the motion of all observers, and that space and time are interconnected in a single continuum. This theory, which is now a cornerstone of modern and quantum physics, is known as Einstein’s special theory of relativity. Einstein's proposed idea of a single continuum where space and time are interwoven is what people call “space-time”.
According to this theory, time—which has traditionally been considered an independent entity according to the principles of classical physics—is affected when a body moves through space. This happens because, according to the theory, time and space are connected and part of a single continuum—spacetime.
In this video, we discuss spacetime in absolutely simple words: what exactly is spacetime and how is it related to the force of gravitation and Einstein’s theory of relativity?

Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.

SUMMARY
What is Spacetime? Are space and time the same thing? Space was thought to be nothing, an empty void with no matter in it. In 1908, Hermann Minkowski postulated that time could be thought of as a 4th dimension along with the three dimensions of space. Einstein later showed that this spacetime is a kind of geometry that can bend, affecting the trajectory and passage of time for objects. How can space and time be part of the same canvas? Space is measured in meters, while time is measured in seconds. How are the two interchangeable?
The definition of spacetime is the set of points in space and time, located with 4 numbers. This would be the location in 3 dimensional space and a time. You can also call these events.
In ordinary Euclidean space, the distance between two point A and B is fairly simple to figure out. The straight line between them is the shortest path. And it’s obvious also that any other path, from A to B will be longer.
If we change one of the coordinates to time, the math that we need is not based on Euclidean geometry, but Minkowskian geometry (or Minkowski Geometry). The straight line between A and B does not represent distance but time elapsed between two events. A straight line represents traveling at a constant velocity between the two events, and is the MAXIMUM duration. So for example, in spacetime, if you took a curved path from event A to event B, or a zig zag path, then the elapsed time would be lower compared to the straight line between A and B, because you will have traveled more in space than in time.
Einstein showed that there is no such thing as absolute time, and so that’s why we have a new formulation. But how do you add time and distance together, since the units are completely different? The key is that there in important conversion factor between time and space, that allows us to convert one to the other. And that conversion factor is, the maximum speed limit of the universe, that is, as far as we know, is the speed of light. The speed of light is the key to uniting space and time. We call this maximum speed “c” in physics.
And c is 299,792,458 meters per second. As you know speed is distance over time. If we multiply this speed by time, we get a distance. So now we can convert time in the same equation to distance – distance = c*t. Thus, the equation works by using this conversion factor.
This formulation for a 2 dimensional spacetime can be extended to the real 4 dimensional spacetime we live in. And that 4 dimensional geometry is the foundation for understanding General Relativity, with the addition that this spacetime is no longer flat, but can curve and contort. So the math gets complicated in General Relativity. The consequence of a curving spacetime is that this results in gravity.
Why do we have only 3 dimensions, why not more? And why not more than one time dimension? First, large spatial dimensions probably don’t exist because we would have detected them if they did. And more than one dimension of time could result in closed time-like loops, in other words it would allow travel to the past. This is considered an impossibility because it would break causality.
More than 3 spatial dimensions would also likely have fatal consequences. In 1920 Paul Ehrenfest showed that our orbit around the sun would be impossible if we had an additional spatial dimension. Other problems have also been identified, for example the orbit of the electron in atoms would become unstable.
#spacetime
If we had fewer spatial dimensions, then spacetime would be too simple for life. For example if we had only one spatial dimension, then orbits could not form. Two dimension would also probably be too simple to result in life.

There are cosmic events so powerful that they leave permanent marks on the fabric of the universe itself. Imagine two colossal black holes spiraling into each other, yes they send ripples in the fabric of spacetime—gravitational waves that we’ve only recently learned to sense. Ripples pass, leaving the pond … or the universe … unchanged when they’re gone. But ripples aren’t the only type of wave. There’s another type of wave that leaves a permanent mark—a memory etched in the fabric of the universe. They’re akin to gravitational tsunamis, and we’re on the verge of being able to detect them.

In 1919, Arthur Eddington led an expedition to observe a total solar eclipse, confirming that light passing near the Sun is deflected due to its gravity. This observation supported Einstein's theory of general relativity, which differs from Newton's laws by predicting that massive objects warp spacetime, affecting the path of light.
Einstein resolved a paradox wherein photons traveling different distances (AB vs. CD) near a massive object like the Sun reach their destination simultaneously. According to special relativity, light's speed is constant, so photons traveling a shorter path (CD) should take less time. However, in general relativity, the presence of a massive object causes time to slow down, an effect called gravitational time dilation.
To visualize this, imagine spacetime as a cylinder that, when influenced by a massive object, flares into a cone. Clocks lower in the gravitational field (closer to the cone's wide base) tick slower than those higher up, explaining why time passes differently at different altitudes. This effect has been experimentally confirmed, such as with atomic clocks on airplanes running faster than those on the ground.
Gravitational time dilation can be visualized by imagining two ants, one higher (A) and one lower (B) on the cone. Both move through spacetime at the same speed, but B's clock ticks slower due to the cone's shape. Thus, B ages slower than A.
This curvature of spacetime not only affects the flow of time but also creates gravity. Objects naturally follow the curved paths in spacetime, leading them to fall towards massive bodies. A stationary object's path in curved spacetime slopes toward the massive body, causing it to fall, illustrating that gravity is the manifestation of curved spacetime geometry. This explains why an object falls faster as it moves closer to a massive body and why, hypothetically, an object falling infinitely would reach the speed of light due to the extreme curvature of spacetime.

Here’s the story we like to tell about the beginning of the universe. Space is expanding evenly everywhere, but if you rewind that expansion you find that all of space was once compacted in an infinitesimal point of infinite density—the singularity at the beginning of time. The expansion of the universe from this point is called the Big Bang. We like to tell this story because it's the correct conclusion from the description of an expanding universe that followed Einstein's general theory of relativity back in the 19-teens. But since then we've learned so much more since then. Does our modern understanding of the universe still insist on a point-like Big Bang? Recent work actually gives us a way to avoid the beginning of time.

Time travel has fascinated humanity for generations, intertwining scientific theories and imaginative storytelling. From Einstein's groundbreaking theory of relativity to the speculative concept of wormholes, this captivating topic invites questions about the nature of time and our place within it.
Einstein's theory of relativity introduced the idea that time is not a fixed constant but a flexible dimension interconnected with space, forming what we know as space-time. This revolutionary concept suggests that under certain conditions, such as traveling at nearly the speed of light or being near massive objects, time can stretch or contract. This phenomenon, known as time dilation, offers a theoretical foundation for moving through time, albeit with practical limitations that challenge our current understanding of physics.
Among these challenges are the immense energy requirements and the need for exotic materials like negative energy. Scientists speculate that such materials might stabilize space-time distortions or even sustain wormholes, theoretical tunnels connecting distant points in space and time. While intriguing, these ideas remain speculative and unproven, existing more in the realm of theoretical physics than applied science.
Equally compelling are the time travel paradoxes that arise when altering the past. The famous grandfather paradox questions whether changing past events could disrupt the causality that led to the traveler's existence. Solutions to such paradoxes range from the speculative notion of alternate universes to the idea that time may be self-consistent, with past events unchangeable.
Time travel also thrives in the realm of science fiction, inspiring countless stories and novels that explore its possibilities and ethical implications. Iconic works like Frank Herbert’s Dune, Kim Stanley Robinson's Red Mars series, and Octavia Butler's Kindred bring imaginative depth to the topic. Theories of space-time manipulation, causality, and futuristic technology are woven into tales that reflect humanity’s curiosity and creativity.
Recent books, including Liu Cixin’s Three-Body Problem and Ted Chiang's Stories of Your Life and Others, continue to push the boundaries of sci-fi novels, offering fresh perspectives on time travel and space-time theories. Audiobook adaptations and new releases, such as the Foundation series by Apple, make these concepts accessible to diverse audiences, showcasing the intersection of science, philosophy, and narrative.
Exploring time travel not only deepens our understanding of theoretical physics but also inspires profound questions about the universe. Whether through best sci-fi books or groundbreaking research, the journey toward uncovering the truth behind time travel continues to captivate and challenge humanity.

Spacetime
In physics, spacetime is any mathematical model that combines space and time into a single interwoven continuum. The spacetime of our universe has historically been interpreted from a Euclidean space perspective, which regards space as consisting of three dimensions, and time as consisting of one dimension, the "fourth dimension". By combining space and time into a single manifold called Minkowski space, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.
Explanation
In non-relativistic classical mechanics, the use of Euclidean space instead of spacetime is appropriate, because time is treated as universal with a constant rate of passage that is independent of the state of motion of an observer. In relativistic contexts, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow the passage of time for an object as seen by an observer outside the field.

Let’s talk about the best evidence we have that the theories of quantum physics truly represent the underlying workings of reality.
You can signup for your trial to The Great Courses Plus at: http://ow.ly/bugR30hIvbu
Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the physicists are definitely on the right track. We know this because the predictions of quantum field theory stand up to experimental test time and time again.

In this episode we dive deeper into the relationship between space and time and explore how we can geometrically map the causality of the universe and increase our understanding of how time and distance relate to one another.

Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time dilation. But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation of time dilation and Einstein’s theory of relativity and also explain how time slows down in a moving vehicle!

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space Time as he discusses Newton and Einstein's dispute over inertial frames of reference. Is Einstein's theory inconsistent? Is gravity even a force??? Check out the episode to find out!

You’ve probably known OF E=mc² since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc² explained to you properly? Mass equalling energy is mostly true, but E=mc² actually describes a much more interesting, and frankly mind-blowing aspect of reality that likely wasn’t covered in your high school physics class. Join Gabe on this week’s episode of PBS Space Time he discusses THE TRUE MEANING OF E=mc²

How do we study nothing? An empty jar still contains something: molecules of air and a bath of infrared light from its warm environment. But what if we suck out every last molecule of air, chill the jar to absolute zero, and shield it from all external radiation? The jar would contain only empty space, but it turns out that empty space is far from nothing.

Of all the unlikely ends of the universe, the Big Rip has to be the most spectacular. Galaxies ripped to shreds, dogs and cat first living together, then tragically separated by the infinitely accelerating expansion of space on subatomic scales. Good thing it's not going to happen. Or is it?

Directing by Andrew Kornhaber
The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is, for the most part, nicely described with a constant density of dark energy – the same amount of this stuff in every block of space. Which means if you increase the volume you increase the overall amount of dark energy – hence accelerating expansion. Mathematically we describe a constant energy density with the cosmological constant in the equations of Einstein’s general theory of relativity. But what if dark energy is NOT constant? What if the energy density in each patch of space increases over time? In that case, the acceleration itself could be … accelerating. That would be bad.
