Have you ever stopped to ask yourself, "what is time?" We all understand its passage intuitively, experientially. But does time actually exist? Is it a force of nature? A tangible entity? I spoke with theoretical physicist and perhaps the world's premier expert on the science of time, Sean Carroll, to learn more.

Time is one of the most important aspects of our lives yet it goes largely unexamined throughout daily life. This film explores a fundamental question regarding time: why does it move in only one direction? We examine this question through an understanding of entropy, a basic concept in physics that many are not aware of. We hope that this film will help the audience increase their understanding of the concept of entropy while at the same time promoting an interest in deeper questions regarding the nature of time.

On May 30, 2012 the 5th annual World Science Festival opened with a showing of Icarus at the Edge of Time. Written by Brian Greene, adapted by David Henry Hwang, film by Al and Al, score composed by Philip Glass, conducted by Brad Lubman, and narrated by LeVar Burton.

After 7 billion years of travel, high and low energy photons arrive at NASA's Fermi spacecraft a mere 900ms apart, suggesting that space-time isn't the bubbly foam of quantum theory but seems closer to Einstein's smooth rubbery membrane.

In this excerpt from his lecture for The Floating University, Dr. Kaku explains that time machines do not violate Einstein's laws of physics, and that – difficult though it might be – future humans would be wise to build one and slip through a wormhole to one of the alternate dimensions proposed by string theory before the cooling universe extinguishes all known life.

It's obvious that time has a direction: you were younger a decade ago than you are today. But according to the laws of physics, there is no intrinsic difference between the past and the future. In our latest One-Minute Physics animation, guest narrator Sean Carroll, a physicist at the California Institute of Technology in Pasadena, explains why a better understanding of the big bang will help explain the arrow of time.
