Question

What is the largest number known?

Answer 1

Infinity, symbolizing an unending number.  If you want a real number, then take 9.9999 to the power of 10 the power fo 10 to the power of 10, as many times as possible in the universe.  There are more mathematical an d sympler ways to list large numbers, such as through probability, like 1000P1000 is a very large number, and 10 to the power of a googol.  A googol is 1 followed by 100 zeros, so imagine a number with a googol zeros.  Then imagine 10 to the power of a googol googol, and so on.

Answer 2

I dunno...but I am pretty sure that no man can count to it in one lifetime. I'm pretty sure it is equal to all the grains of sand on every beach in the entire world. Go ahead....start counting.

Answer 3

The simple answer is that there is no largest number; because whatever number you think of, you can always double it.  Numbers do tend towards a limit, referred to as infinity; but infinity itself is not a number.  Strange things happen, as you approach infinity (for example, the chance of an exceedingly unlikely event ocurring becomes certain).

However, there are numbers that go beyond the concept of infinity.  For example, infinity is usually taken to be the limit of counting numbers (1, 2,3 ... etc).  It can be shown that all fractions can be accommodated on the number line (ie, they can be counted).  It has been proven however, that even an infinite number is not sufficient to account for all the decimals (or another way of putting it, no matter how close fractions are to one-another, there will always be a space between them for an infinite number of decimals).

Thus, to account for all the decimals, we need a number 'higher' than infinity.  Even then, it can be shown that such  'transfinite' numbers cannot account for the number of points on a curve, and yet another 'higher' level of infinity is needed.

This sounds a bit complicated, but if you googled 'George Cantor', you would find some sites that explain his 'discontinuity' theory quite well.

Answer 4

A-a-a-a lot.

Answer 5

You're joking right?

Answer 6

There is no largest number.  It can go on into infinity.  We might run out of names to call it, but usually, for very large numbers, we use scientific notation, eg:  

160 billion would be 1.6 x 10^9th power.
