Big Post: Big Numbers

For some things, 100 is a big number. For this, my One Hundreth Post, I'd like to share another very large number I came across the other day. It's one hundred million billion billion billion billion billion. It looks like this:
1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
(or so I've been told...he said it was a 10 with 53 zeros after it)
