The **Googolplex **is not to be confused with the Googleplex (Google, Inc.’s Headquarters). Googolplex is the name of a number (just like π = 3.14…). A very large number…

1 Googolplex = 10^{10100}

This is how you would write out a googolplex. That is the highly

**compact**version. To get an idea of how BIG a googolplex is, here is the observable universe:

Now keep in mind that it has been estimated that there are approximately **10**^{82 }hydrogen atoms in the Observable Universe. This Article explains how that number is derived. Of course, this is a VERY rough approximation. However, it gives you an idea of how big a Googolplex is. So big that not even the H atoms in our observable universe come close.

We have already established that a Googolplex is a very “large” number. So what happens if you decide to count to one googolplex? Turns out you probably can’t. Not unless you are immortal… and have a lot of time to spare… and find a new universe to do it in because this one will be gone by then.

A person counting at two numbers a second, would take this long to reach these:

One million5 days, 18 hours, 53 minutes, 20 seconds One billion15 years, 308 days, 9 hours, 41 minutes, 50 seconds One googol1.584 x 10 ^{90}centuries!!!One googolplex5 x 10 ^{10^99}seconds. We can’t convert that into centuries or anything because our calculators can’t handle numbers that big (not to mention our brains).-The Procastinators Club, The Almighty Googolplex

Still can’t get your head around the enormity of the Googolplex? Worry not! It’s perfectly normal. Here is a song by Helen Arney that will put your mind at ease (or not).
