Текст песни How Will We Know?

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,Flaming Lips - How Will We Know? - http://ru.motolyrics.com/flaming-lips/how-will-we-know-lyrics.html
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?
