What are you babbling about here? The Big Bang took place at midnight? Or actually a second before then? Ooookay... I've seen a ton of shows on the Big Bang and so forth, and never seen the kind of cartoon presentation you assert.
Try paying more attention next time.
Find someone who READS ENGLISH to read it to you next time.
The QUESTION IS, WHAT OR WHO TRIGGERED, SET OFF, DETONATED, TRIPPED (I'm running out of ways to try to get you to understand this) that BIG BANG??????
