How many germs are there in the whole world?

Answer 1

1 Googleplex.

or 1 x 10 to the power of 100

or 1 with a googlo of zero's

or a number with 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0000

zero's infront of it.

which the universe in itself is to small to write that many zero's on a piece of paper going from one end of the universe to the other.
