"This now tells how precise the Creator’s aim must have been, namely to an accuracy of one part in 10 to the 10123rd power.
Do you know the odds of you existing and sitting there reading this? The universe would need to have come into existence (use Penrose’s figure for that), then you would have to come into existence (and there is an infinite number of ways that you wouldn’t be here as opposed to being here, but let’s drop the odds an infinite amount and use Penrose’s figure again).
Let’s call the Penrose number P. That means for you to be reading this requires the odds of a minimum of P x P.
So either:
You are reading this and the figure is meaningless or…
The chances of the universe existing is less than the chance of you reading this (by a factor of P) and as you are reading this the universe must have come to exist or…
You are not actually there, in which case I’m wasting my time writing this (which I actually think I am even if you are).
You do not seem to understand odds. If something has already happened, then the odds of it having happened are exactly 1.
