Imaginary Numbers

Colin is showing a lot of interest in numbers. He adds numbers for fun.

Recently, we mentioned that the largest number actually named by scientists is a googolplex. He was quite fascinated by this, and quickly grasped that it cannot be the largest number that exists, because you can always add one to any number. That's my guy.

He has been trying ever since to wrap his head around the number, which is, of course, asking a lot of a four-year-old's brain, since the number only exists in order to illustrate the difference between an unimaginably large number and infinity.

But, in the end, he decided that since there has to be numbers larger than a googolplex, it is up to him to name them. So far, my favorites are "a bagel" and "a million trillion billion car dinosaur."

I wonder if 10 to the power of bagel is a bagelplex?
