What's the highest number?

Answer 1

There is no highest number. You can always add another 1 or 0 to any figure and it will be always higher then the one before.

However, mathematics have come up with a symbol for a "never ending" number. which is the 8 turned horizontally.

Answer 2

Of course, because our number system is infinite, there is not a number that is the 'biggest', since you can always add 1. However, there is a Googolplex. It is 10^10^100, or a 1 followed by one googol of zeros. One googol is greater than the number of elementary particles in the known universe, which has been variously estimated from 1072 up to 1087. Since a googolplex is one followed by a googol zeroes, it would not be possible to write down or store a googolplex in decimal notation, even if all the matter in the known universe were converted into paper and ink or disk drives.

Thinking of this another way, consider printing the digits of a googolplex in unreadable, 1-point font. TeX 1pt font is .3514598mm per digit, which means it would take about 3.5\times10^{96} meters to write in one point font. The known universe is estimated at 7.4\times10^{26} meters in diameter, which means the distance to write the digits would be about 4.7\times10^{69} times the diameter of the known universe. The time it would take to write such a number also renders the task implausible: if a person can write two digits per second, it would take around 1.1\times10^{82} times the age of the universe to write down a googolplex.

Please go to http://en.wikipedia.org/wiki/Googolplex to learn more about it. It's uber interesting!!!

Answer 3

There is no highest number. Any number you think might be the highest, can have 1 added to it.

Answer 4

Well, it certainly is NOT infinity. As you have certainly seen equations with invinity + x and infinity +12 and so on So you know that there is indeed a larger number than infinity .

What you are asking has no defenite numberical value because the limits of the number system extend out beyond infinity.

Answer 5

There is no highest number - Any number you can imagine, I can always add 1 to it and make it a little bit bigger...

This concept is reflected in math with 'infinity' (the symbol looks like an 8 on it's side)...This means basically 'forever large'.

For instance, 1/X - As x gets smaller and smaller, 1/x gets bigger and bigger (1/.1 = 10, 1/.01 = 100, 1/.0000001 = 1,000,000, and so on) - As X gets closer to zero, 1/x gets really, really, really huge - so huge that 1/0, in higher math, is often treated as Infinity.

Make sense?

Answer 6

There really is no highest number. While infinity represents extremely large numbers, it really isnt a number. Infinity represents the idea that numbers keep increasing without end. No matter what number you choose, there is always a larger one.

Answer 7

inifinity
In mathematics, "infinity" is often used in contexts where it is treated as if it were a number (i.e., it counts or measures things : "an infinite number of terms") but it is clearly a very different type of "number" than the integers or reals. Infinity is relevant to, or the subject matter of, limits, aleph numbers, classes in set theory, Dedekind-infinite sets, large cardinals, Russell's paradox, hyperreal numbers, projective geometry, extended real numbers and the absolute Infinite.
