10^100 is termed a googol but 10^(10^100) is a googolplex.

That being said, I watched a vid recently on youtube where its said that "if the universe were a googolplex metres in 'width' then there would be more than one of 'you'".

Basically a way to show how large the googolplex as a number actually is.

To say that there would be more than one of 'you' is the implication that every space in the universe has reached its limit on the different possibilities on what can exist in it, in terms of different combinations of particles that can exist within a defined space (be it a 1mm^3 for example).

With all possibilities reached the universe would be left to repeat itself over and over using possibilities that have already been 'done' so to speak.


Its a bit of a mind f##k to say the least.

Its a mathematical concept for sure, and I'm not sure how it ties in with concept of infinity, but the definition of repeating persons with a large enough universe would have to be 'tightened' some what for me to be able to grasp it.

Just thought I'd add this little factoid in to this thread as an example of the other end of the scale .....

If you were to scale up a single hydrogen atom so that it was the size of the observable universe, a string loop* would only be the size of a tree.

  • string loops are the components of string theory.

It took me a while to visualize that, well not visualize but just get my head around the concept of the size and scale of things involved.


Source of factoid is a youtube vid:
