Science & Mathematics - 4 January 2007

I guess the question that I am asking is what if anything was before the universe. I can't get my head around there was NOTHING but then SOMETHING went bang.

We live in Michigan and we haven't seen but about 4 inches of snow all winter. For the first Christmas in 16 years we didn't have any snow. Did anyone on here happen to see snow for Christmas? Is it snowing where you are now? It has been in the high 40's since the end of November. I am not complaining just asking.

I've been out of school 15 years but I'm going back. I have to take a statistics course to get into grad school. I've heard it's pretty tough with lots of formulas to remember. Any suggestions to what I need to know which may make this class a little less difficult?

SC has always baffled me. It seemed sort of impossible. But has it been truly documented that it has happened, or are all these cases of SC fake, meaning that SC is a myth? Please, help out a confused person.

What if humans existed like frequencies on a radio? Their could be multiple existences going on right now, but you only know of the ones on your frequency. What if you were standing right next to someone right now, but you would never know because they are on a different frequency? This is an actualy theory, does anyone have any comments or explanations?
