Cosmic Time 5 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?

the fact that people from the future are not warning us about future catastrophe's is because we never achieve time travel. or our time now is that insignificant, regardless of how "important" we think we are.

@madridisinSpain I don't know how you see Bieber, if you like him or not, but how is Kaku your Bieber?

[InvertedHorizon]

@Ayokalyb Or that we've all died out in the future.

there's alot of paradox' like, a man builds a time machine, goes 2 minutes into the past and walks behind himself getting ready to go 2 minutes into the past, and shoots himself in the back of the head. how does he shoot himself before he leaves?

[phobiazzzero]

@Ayokalyb maybe just because you can get back in time but only at the point of time travel device invention

09:44 Why is there sound and how can we see it from the outside?

I still liked the video though! :)

@Ayokalyb or because future humans knew of the danger of interrupting the space time continuum and thus decided not to interact with us.

[Timdenomad]

or maybe they have changed things and we were spared from many more catastrophes, but how would we know?

Time cannot be viewed in the past by peering into space. The universe is 13.7ba nothing can be viewed 13.7 billion light years away. There should be no galaxies found at that distance. Matter cannot travel faster than light. Eventually we will find that light does not exist until it's electromagnetic wave collapses. This action occurs in an instant. Distant objects are viewed in the present, not in the past. Evidence to this, see HawaiiEdu, "Tomotsugu finds galaxy 12.8 billion light years away."

@Ayokalyb Oh perhaps they have finally understood the concept of chaos...

[HimesInu]

@Ayokalyb Or that you can't change that which has already occurred.
