A video clip that caught my attention

Googol and Googolplex - Numberphile



This video talks about Googol and Googolplex, and what if the Universe was a googolplex across.
I have learnt that:
  • A googol is 10^100, which is 1, followed by a hundred zeroes.
  • A googolplex is 10^10^100, which is 1, followed by a googol of zeroes
  • If the universe was a googolplex across, you would be able to see repetitions of yourself, since all the different arrangement of particles is 10^10^70, and that a googolplex is bigger than that, we are definitely able to see repetitions of ourselves if we travel far enough.
