How Will We Know? (Futuristic Crashendos)

How will we know

If this rush of noise we're hearin'

is the world's biggest hammer

comin' down on our heads crushing our lives,

and everything that we've said,

crushing the existence of any small effects we've had

or is it just some super-sonic flux invented in the future

blowin' up so hard you can hear it before it happens

... how will we know?
