[00:00.59][Magnus Magnusson]I'd like to start,if I may,with Professor Hawking [00:04.49]How did the universe start?With a big bang? [00:07.97][Stephen Hawking]We observe that distant galaxies are moving away from us [00:12.82]They must have been closer together in the past [00:17.45]It was the beginning of the universe [00:19.78]And of time itself [00:23.07]Anything that happened before the big bang [00:25.41]Could not affect what happened after [00:28.02][Richard Dawkins]The poetry of the expanding universe [00:30.60]The poetry of the complexity of life [00:33.13]We're not normally equipped to understand [00:35.75]And science gives it [00:38.39]Science is opening your eyes [00:40.62]To the wonderfulness of what's there [00:43.34]Science is opening your eyes [00:45.68]To the poetry of the expanding universe [00:52.26]We come to you, Carl Sagon.Could you help me [00:53.66]by putting in layman's terms [00:55.99]What was involved with the big bang [00:58.52]The early cosmos was everywhere white hot [01:02.91]But then as time passed [01:05.31]The radiation expanded and cooled [01:08.55]Then ,little pockets of gas began to grow [01:13.62]Steadily brightening, we call them the galaxies [01:18.02]It was the beginning of the universe [01:20.20]And of time itself [01:23.66]Anything that happened before the big bang [01:26.10]Could not affect what happened after [01:28.79]The poetry of the expanding universe [01:31.33]The poetry of the complexity of life [01:33.77]We're not normally equipped to understand [01:36.38]And science gives it [01:38.81][Tara Shears]In the big bang we had equal amounts of matter and anti-matter [01:43.62]And as soon as they met each other [01:46.22]They annihilated together [01:48.58]And this battle played out [01:50.56]Whilst the universe expanded [01:53.12]In its first minute of existence [01:56.49]They annihilated together [01:58.54]And this battle played out [02:00.53]Whilst the universe expanded [02:03.34]In its first minute of existence [02:09.17][Neil Tyson]It's not all that hard to detect the big bang [02:11.66]All you need to do is change the channel [02:14.34]Until you come between two stations [02:16.73]All you need to do is change the channel [02:19.07]About one percent of the snow and noise [02:21.72]Comes from the big bang itself [02:24.09]We're all eavesdropping [02:26.48]On the birth pangs of the cosmos [02:28.68]It was the beginning of the universe [02:30.88]And of time itself [02:32.96]And this battle played out [02:34.28]Science is opening your eyes [02:36.45]To the poetry of the expanding universe [02:39.70]And this battle played out [02:40.93]Whilst the universe expanded [02:43.58]In its first minute of existence [02:46.76]It was the beginning of the universe [02:48.58]And of time itself
