It's me, anemone.

I saw this problem quite some time ago, and I don't remember where...but it says "Can a googol $10^{100}$ be written as $n^2-m^2$, where $n$ and $m$ are positive integers?"

Since I don't know where I should start to think about how to answer it, I thought there would be no harm in asking about it here because

**MHB**knows it all!

Thanks in advance for any input that anyone is going to give me.
