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...

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 un...

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...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself constant, which will surely result in ultimate heat death. But a recent survey of primordial sound waves frozen into the way galaxies are sprinkled through the universe reveals that this fate is now in question.

The fundamentals of space-time: Part 1 - Andrew Pontzen and Tom Whyntie
View full lesson: http://ed.ted.com/lessons/the-fundamentals-of-space-time-part-1-andrew-pontzen-and-tom-whyntie
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.

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.

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?

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.

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself constant, which will surely result in ultimate heat death. But a recent survey of primordial sound waves frozen into the way galaxies are sprinkled through the universe reveals that this fate is now in question.

What is the deepest level of reality? In this Quanta explainer, Vijay Balasubramanian, a physicist at the University of Pennsylvania, takes us on a journey through space-time to investigate what it’s made of, why it’s failing us, and where physics can go next.

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.
Lesson by Andrew Pontzen and Tom Whyntie, animation by Giant Animation Studios.

What are the consequences of playing with the SPACE-TIME CONTINUUM? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down the space-time continuum in real life and in pop culture.
Find out about Einstein's special theory of relativity and our four dimensions. Neil and Chuck make lunch plans as they navigate space and time. What critiques does Neil have of The Terminator and Back to the Future? What are some unintended complications of time travel? Discover the concept of worldliness, getting unstuck from time in Slaughterhouse 5, and how time travel is just a changing of dimensions.
About the prints that flank Neil in this video:
"Black Swan” & "White Swan" limited edition serigraph prints by Coast Salish artist Jane Kwatleematt Marston. For more information about this artist and her work, visit Inuit Gallery of Vancouver. https://inuit.com/
