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
