Cosmic Time 2 of 6

PLAYLIST: http://www.youtube.com/watch?v=yjE5LHfqEQI&feature=PlayList&p=4E0DF0A...

In this four-part series, string theory pioneer Michio Kaku goes on an extraordinary exploration of the world in search of time.
He discovers our sense of time passing and the clocks that drive our bodies. He reveals the forces of time that make and destroy us in a lifetime. He journeys to some of the Earth's most spectacular geological sites to look for clues to the extraordinary depths of time at a planetary level. Finally, he takes us on a cosmic journey in search of the beginning (and the end) of time itself.

Part 4: Cosmic Time
We've always structured our lives based on an unchanging past and a predictable and ordered future. But atomic and cosmic discoveries have changed all that. What is time itself? And will it ever end?

Time is pretty weird. In my Calculus lecture, it flows forward and then backwards... Therefore a 50 min. lecture feels like a 3 hour lecture instead.

i always thought the speed of ur movement has nothing to do with time, but seriously what do i know. seems like regardless of how fast something is moving it still exists and is just moving more quickly across matter than something else. why does the speed at which space is covered must have some relation to the time it was covered in? (im familiar with space time idea) just dont see how it slows the time,?

Time is relative only to being alive, conscious or self aware. Time would not exist if there were no consciousness to perceive it.

@gerbengeeraerts Thats simply how we measure time......time its self is a mystery....i guess it's a term for aging or growing younger or moving through space......it is confusing.......we're not yet evolved enough to fully grasp it.......

@goldensleeves You can....If you were perfectly still and the universe was moving at the speed of light your perception of it would differ to those going along with it.....this though would imply that you can be separate or even outside the universe which is (by our current understanding) impossible because your a part of it....also its much easier to use something people can relate to like a train.....the train isn't important though...
