There is no terror in the bang, only in the anticipation of it. Alfred Hitchcock
If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form. Stephen Hawking
This is the way the world ends, not with a bang, but a whimper. T. S. Eliot
Your body is like a piece of dynamite. You can tap it with a pencil all day, but you'll never make it explode. You hit it once with a hammer: Bang! Get serious. Do 40 hard minutes, not an hour and half of nonsense. It's so much more rewarding. Jason Statham
The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it. Stephen Hawking
