If you filled out a bracket sheet for every possible outcome and stacked them up, it would reach the sun 6,115 times, or the sheets would cover the surface of the Earth 158,473 times - at a depth of nearly 50 feet. Also, even if you got all of yesterday's [March 15] games correct, your odds of picking the perfect bracket is 1 in 9.2 quintillion.
Quintillion?!? My question is "how?" and I answered my own question through Google. Long ago, My estimates inside thoughts: it could take millions to get perfect 65-team bracket..... and I am dead wrong.
I couldn't come up to think of killing myself to say infinite number like googolplex...
