Question

Explain the concept of Graham's number.

Answer 1

This number is so astronomically large that it is beyond human comprehension.

Let's start with the number 3.

Now, lets do 3^3.

That is 27.

Now, lets do 3^27

Thats 7.12 trillion

Now, lets do 3 ^ 7.12 trillion

Thats 3*3*3*3*3......7.12 trillion times

There is not a single supercomputer in the entire world that can do that calculation in a resonable amount of time.

Lets call that last calculation, 3*3*3*3*3......7.12 trillion times, G1

So we know that G1 is an enormous number.

Now we do 3^G1

And we call that G2.

Next we do 3^G2

And we call that G3.

We repeat this process of enormous, exponential growth until we reach G64

And G64 is Graham's number.
