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
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
The early cosmos was everywhere white hot
But then as time passed
The radiation expanded and cooled
Then little pockets of gas began to grow
Steadily brightening, we call them the galaxies
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
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 eavesdropping
On the birth pangs of the cosmos
