The Moment Is Structured That Way

From Kurt Vonnegut’s Slaughterhouse-Five:

‘How-how does the Universe end?’ said Billy.

‘We blow it up, experimenting with new fuels for our flying
saucers. A Tralfamadorian test pilot presses a starter button, and the
whole Universe disappears.’ So it goes.

“If You know this,” said Billy, ‘isn’t there some way you can
prevent it? Can’t you keep the pilot from pressing the button?’

“He has always pressed it, and he always will. We always let him
and we always will let him. The moment is structured that way.’

“Alan Boyle reports on litigation over the Large Hadron Collider, and claims that it will bring about the end of the world universe.”
