[01:12.590]The questions I would like to talk about are:
[01:18.490]one, where did we come from?
[01:22.900]How did the universe come into being?
[01:27.010]Are we alone in the universe?
[01:30.060]Is there alien life out there?
[01:33.050]What is the future of the human race?
[01:36.570]Up until the 1920s,
[01:39.220]everyone thought the universe was essentially static and unchanging in time.
[01:45.090]Then it was discovered that the universe was expanding.
[01:49.750]Distant galaxies were moving away from us.
[01:54.620]This meant they must have been closer together in the past.
[01:59.250]If we extrapolate back,
[02:01.390]we find we must have all been on top of each other about 15 billion years ago.
[02:08.660]This was the Big Bang, the beginning of the universe.
[04:16.090]good bye our galaxy
[04:47.910]But was there anything before the Big Bang?
[04:51.970]If not, what created the universe?
[04:55.770]Why did the universe emerge from the Big Bang the way it did?
[05:01.570]We used to think that the theory of the universe could be divided into two parts.
[05:07.840]First, there were the laws given its state over all of space at one time.
