What is the world's biggest number?

Answer 1

There is no biggest number.

For every number there is a bigger number. Take any number, call it r. Then r+1 is bigger than r. So there can be no biggest number, since you can always add one to any number.

Infinity is bigger than all the natural numbers (numbers like 1,2,3. . . ) and all the real numbers (numbers like 1.23456436435. . . . , 1/2, 145.9879845. . . ), but there are numbers that are bigger than infinity. Imagine you had infinity objects. Then count all the possible groupings of those objects, (for example, the third object by itself could be one grouping, and the first, third and fourth together could be another grouping). The number of possible groupings of the infinity objects is bigger than the number of objects.
