**10 ^{100}**, an extremely compact method, to easily represent the largest numbers (and also the smallest numbers). With the smallest of effort, you can also present it in the full format: a “one” followed by one hundred “zeros”.

What's bigger than a googolplex? Even though a googolplex is immense, Graham's number and Skewes' number are much larger. Named after mathematicians Ronald Graham and Stanley Skewes, both numbers are so large that they can't be represented in the observable universe.

(This might sound familiar, as Google was named after this number, though they got the spelling wrong.) Graham's number is also bigger than a googolplex, which Milton initially defined as a 1, followed by writing zeroes until you get tired, but is now commonly accepted to be 10^{googol}=10^{(}^{10}^{100}).

Googol: A googol is most easily expressed as 10^{100}. That means it is a one followed by one hundred zeros. The number was referenced by Edward Kasner in his 1940 book, Mathematics and the Imagination, according to Live Science. Kasner credits his nine-year-old nephew for giving the value its name.

If infinity plus one is infinity, the only number that could be just before infinity is also infinity!

There is no biggest, last number … except infinity. Except infinity isn't a number. But some infinities are literally bigger than others.

Written out in ordinary decimal notation, it is 1 followed by 10^{100} zeroes; that is, a 1 followed by a googol of zeroes.

These numbers are quintillion, sextillion, septillion, octillion, nonillion, and decillion.

Google is the word that is more common to us now, and so it is sometimes mistakenly used as a noun to refer to the number 10^{100}. That number is a googol, so named by Milton Sirotta, the nephew of the American mathematician Edward Kasner, who was working with large numbers like 10^{100}.

TREE(3) is a colossus, a number so large that it dwarfs some of its gargantuan cousins like a googol (ten to the one hundred), or a googolplex (ten to the googol), or even the dreaded Graham's number (too big to write). TREE(3) emerges, quite spectacularly, from a mathematical game known as the Games of Trees.

A googolplex is a 1 followed by a googol of zeros.

It's impossible to write out, but in scientific notation it looks like 1 x 10^{10}^{^}^{100}.

INFINITY IS THE BIGGEST NUMBER FOLLOWED BY OMEGA (even though they are not real numbers) thats the answer to your question.

Googolplex may well designate the largest number named with a single word, but of course that doesn't make it the biggest number. In a last-ditch effort to hold onto the hope that there is indeed such a thing as the largest number… Child: Infinity! Nothing is larger than infinity!

A unit of quantity equal to 10^{66} (1 followed by 66 zeros).

Zillion sounds like an actual number because of its similarity to billion, million, and trillion, and it is modeled on these real numerical values. However, like its cousin jillion, zillion is an informal way to talk about a number that's enormous but indefinite.

noun, plural cen·til·lions, (as after a numeral) cen·til·lion. a cardinal number represented in the U.S. by 1 followed by 303 zeros, and in Great Britain by 1 followed by 600 zeros. amounting to one centillion in number.

Mathematically, if we see infinity is the unimaginable end of the number line. As no number is imagined beyond it(no real number is larger than infinity). The symbol (∞) sets the limit or unboundedness in calculus.

Googol is 10 to the 100th power, which is 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000. Googolplex isn't just that number but has that many zeros in it. It simply has no other nameable name.

No, gazillion is not a specific number. It is an informal term that refers to a large quantity of something. Examples: 'Mary has a gazillion stamps in her collection.

Visualized this way, you'll see it's possible to keep up this one-to-one correspondence between our sets forever, which means infinity and infinity plus one are actually equal.

There is more than one 'infinity'—in fact, there are infinitely-many infinities, each one larger than before!

Multiplying infinity by infinity will result in infinity.
