I understand the creation of the world from the Big Bang on up, but what caused the Big Bang to happen in the first place?

Best answer goes to the one with a rational explanation without denying the Big Bang, unless they have scientific evidence, or without resorting to mythological forces to explain what they don't understand.

I know that this is a REALLY weird question, but it is raining real hard right now where I live. I was just wondering how many raindrops people receive when it rains. Like, how many drops does a person get every second or minute, or however it goes. And please, no smart remarks or answers because you WILL get reported!!

find the limit as t approaches 0 of this function: sin^2(3t)/(t^2).
In words, the function is sine squared times 3t divided by t squared. Any help with trig limits and derivatives is also helpful.
