The Fourth Dimension?
The nature of Time

Brian Greene is a professor of physics and mathematics at Columbia University. He is one of my favorite smart people because he knows how to present science in a way that is very easy to understand. Below is a documentary on Time hosted by Brian Greene. It is one of my favorites.

We all think of “time” as such a simple concept. Past, present, and future. A flow in one direction only. Things may not be so simple.

Some of the greatest minds in human history have pondered the nature of Time. Is Time really just an illusion, or is Time a real thing?

The idea that time may not be the same for everyone, has huge implications. The idea that all times exist at once may seem crazy, but it very well could be the case.
