Is there a name for a number with 1 billion zeros?

Just curious.

Googolplex?

Probably zillion

I just know that googleplex is the largest

Billtillion.

I remember Sagan's old theory that writing out a Googolplex would take more space than there is in the known universe, so if you're looking for a number with a billion zeroes or more, that's the one you want.

Really friggin' big.

A googol is equal to 1x10^100 (1 followed by 100 zeroes). A googolplex is equal to one followed by a googol of zeroes, that is, 10^10^100. A googolplex is equivalent to 1 followed by 10 billion quintillion quintillion quintillion quintillion quintillion zeroes.

A googolplex is therefore incomprehensibly larger than the number 1 followed by a billion zeroes. There is no official name for that sort of number.

Where'd you get the bolded part? Any link will do.

That's kinda hard to say. It's a huge number.

Willion?

@jhazzroucher: I figured it out myself.

Yes.

Giga as in gigabytes.

Opps, you meant with a billion zeros; I don't think there is a name for such a large number; I don't think our numbering vocabulary is equipped to go up to such a high number.

Batzillion

Pfft. Batzillion transcends infinity to the power of infinity an infinite amount of times.

Oh ya, forgot

Big

Or, for all intents and purposes available to us now, it might as well be infinity

So Googleplexian > infinity?
