[Magnus Magnusson] I'd like to start, if I may, with Professor Hawking How did the universe start? With a 'Big Bang'? [Stephen Hawking] We observe that distant galaxies are moving away from us They must have been closer together in the past It was the beginning of the universe And of time itself Anything that happened before the big bang Could not affect what happened after [Richard Dawkins] The poetry of the expanding universe The poetry of the complexity of life We're not normally equipped to understand And science gives it to us Science is opening your eyes To the wonderfulness of what's there Science is opening your eyes To the poetry of the expanding universe [Magnus Magnusson] We come to you, Carl Sagan Could you help me by putting in Layman's term What was involved with this 'Big Bang'? [Carl Sagan] The early cosmos was everywhere white hot But then as time pa**ed The radiation expanded and cooled Then little pockets of gas began to grow Steadily brightening, we call them 'galaxies' [Stephen Hawking] It was the beginning of the universe And of time itself Anything that happened before the Big Bang Could not affect what happened after [Richard Dawkins] The poetry of the expanding Universe The poetry of the complexity of life We're not normally equipped to understand But science gives it to us [Tara Shears] In the Big Bang we had equal amounts of matter and anti-matter And as soon as they met each other, They annihilated together And this battle played out Whilst the universe expanded In its first minute of existence [Neil DeGra**e Tyson] It's not all that hard to detect the big bang All you need to do is change the channel Until you come between two stations About one percent of the snow and noise Comes from the big bang itself We're all eavesdroppers On the birth pangs of the cosmos [Stephen Hawking] It was the beginning of the universe, and of time itself [Tara Shears] And this battle played out [Richard Dawkins] Science is opening your eyes The poetry of the expanding Universe [Tara Shears] And this battle played out Whilst the universe expanded In its first minute of existence [Stephen Hawking] It was the beginning of the universe And of time itself
