In this Big Think interview, theoretical physicist Sean Carroll discusses the concept of time and the mysteries surrounding its properties. He notes that while we use the word "time" frequently in everyday language, the real puzzles arise when we consider the properties of time, such as the past, present, and future, and the fact that we can affect the future but not the past.
Carroll also discusses the concept of entropy, which is a measure of how disorganized or random a system is, and the second law...

The Physics and Philosophy of Time - with Carlo Rovelli
From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.

Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in th...

The Science of Time Explained by Brian Greene
Theoretical physicist, mathematician, and string theorist Brian Greene explains the science of time. As a general definition, time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. Brian Greene simplifies the concept of time so we can have a better understanding of it.
In general relativity, the physical nature of time is addressed with respect to events in spacetime. For example: The collision of two particles, the explosion of a supernova, or the arrival of a rocket ship.
Brian Greene also explains if its possible to time travel. One of the most frequent questions people wonder when thinking about time is whether its physically possible to go back in time. But a central problem wit...

Do photons experience time?
In relativity theory, fast moving clocks tick more slowly than slow moving ones. The effect increases as one approaches the speed of light. But what happens at the speed of light? Do photons experience time? In this video, Fermilab’s Dr. Don Lincoln lays out what we know about this interesting question.

The earliest time measurements were observations of cycles of the natural world, using patterns of changes from day to night and season to season to build calendars. More precise time-keeping eventually came along to put time in more convenient boxes. But what exactly are we measuring? Andrew Zimmerman Jones contemplates whether time is something that physically exists or is just in our heads.

It's said that the clock is always ticking, but there's a chance that it isn't. The theory of "presentism" states that the current moment is the only thing that's real, while "eternalism" is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don't tell us who wins the big game next year.

Carroll also discusses the concept of entropy, which is a measure of how disorganized or random a system is, and the second law of thermodynamics, which states that there is a natural tendency for things in the universe to go from a state of low entropy to high entropy. He explains that the arrow of time, or the perceived difference between the past and the future, arises due to the influence of the Big Bang and the fact that the universe began in a state of low entropy.
Carroll also touches on the possibility of time travel and the concept of the multiverse.

About Sean Carroll:
Dr. Sean Carroll is Homewood Professor of Natural Philosophy — in effect, a joint appointment between physics and philosophy — at Johns Hopkins University in Baltimore, and fractal faculty at the Santa Fe Institute. Most of his career has been spent doing research on cosmology, field theory, and gravitation, looking at topics such as dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. These days, his focus has shifted to more foundational questions, both in quantum mechanics (origin of probability, emergence of space and time) and statistical mechanics (entropy and the arrow of time, emergence and causation, dynamics of complexity), bringing a more philosophical dimension to his work.

Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.
Carlo Rovelli is a theoretical physicist who has made significant contributions to the physics of space and time. He has worked in Italy and the US, and is currently directing the quantum gravity research group of the Centre de physique théorique in Marseille, France. His books 'Seven Brief Lessons on Physics' and 'Reality Is Not What It Seems' are international bestsellers translated into forty-one languages.

Theoretical physicist, mathematician, and string theorist Brian Greene explains the science of time.

Brian Greene simplifies the concept of time so we can have a better understanding of it.
In general relativity, the physical nature of time is addressed with respect to events in spacetime. For example: The collision of two particles, the explosion of a supernova, or the arrival of a rocket ship.
Brian Greene also explains if its possible to time travel. One of the most frequent questions people wonder when thinking about time is whether its physically possible to go back in time. But a central problem with time travel to the past is the violation of causality.
As for going back in time, it is in direct violation of causality. Giving rise to the possibility of a temporal paradox. Some interpretations of time travel resolve this by accepting the possibility of travel between branch points, parallel realities, or universes.

In relativity theory, fast moving clocks tick more slowly than slow moving ones. The effect increases as one approaches the speed of light. But what happens at the speed of light? Do photons experience time? In this video, Fermilab’s Dr. Don Lincoln lays out what we know about this interesting question.

The earliest time measurements were observations of cycles of the natural world, using patterns of changes from day to night and season to season to build calendars. More precise time-keeping eventually came along to put time in more convenient boxes. But what exactly are we measuring? Andrew Zimmerman Jones contemplates whether time is something that physically exists or is just in our heads.

It's said that the clock is always ticking, but there's a chance that it isn't. The theory of "presentism" states that the current moment is the only thing that's real, while "eternalism" is the belief that all existence in time is equally real. Find out if the future is really out there and predictable—just don't tell us who wins the big game next year.
This video is episode two from the series "Mysteries of Modern Physics: Time", Presented by Sean Carroll
