I’ve been reading Edward Teller’s autobiography.

In a footnote (p. 247), Teller mentions that “the electron in a hydrogen atom will eventually jump to a proton if it is close enough”.

Teller and Francis Owen Rice calculated how long it would take, if the proton is 1 centimeter away.

Their answer was 10100,000,000.

A long time. A “big number”.


That’s the same as 10108, which is more than a googol (10100), but much less than a googolplex (1010100).


What’s that? You want to know what units?

You mean is the 10100,000,000 in Planck times (5.4 x 10-44 seconds), or seconds, or years, or time periods since the Big Bang?

Doesn’t matter. (Think about it.)

That’s how big a number it is.
