Imagine a time when it all began
In the dying days of the war
A weapon that would settle the score
Whoever found it first
Would be sure to do their worst
They always had before
Imagine a man where it all began
A scientist pacing the floor
In each nation, always eager to explore
To build the best big stick
To turn the winning trick
But this was something more
The big bang took and shook the world
Shot down the rising sun
The end was begun and it hit everyone
When the chain reaction was done
The big shots tried to hold it back
Fools tried to wish it away
The hopeful depend on a world without end
Whatever the hopeless may say
Imagine a place where it all began
Gathered from across the land
To work in the secrecy of the desert sand
All of the brightest boys
To play with the biggest toys
More than they bargained for
The big bang took and shook the world
Shot down the rising sun
The hopeful depend on a world without end
Whatever the hopeless may say
Imagine a man when it all began
The pilot of "Enola gay"
Flying out of the shockwave on that 
August day
All the powers that be
And the course of history
Would be changed forevermore
The big bang took and shook the world
Shot down the rising sun
The end was begun and it hit everyone
When the chain reaction was done
The big shots tried to hold it back
Fools tried to wish it away
The hopeful depend on a world without end
Whatever the hopeless may say
The big bang took and shook the world
Shot down the rising sun
The hopeful depend on a world without end
Whatever the hopeless may say
