> As pi is infinite, it also stores any imaginable information.

Whether that is true is related to the normalness [1] of the number pi, but this property has not been proven. See also: [2].

That was a fun read. Ive always thought about this when people say 'THE UNIVERSE IS INFINITE SO WE ARE EATING DINNER AT HELMS DEEP SOMEWHERE'.

Naw man, physics still apply, you dont get gandalf just because you went a few million light years toward Andromedia

There is a great Numberphile video loosely related to this (no magic though)

"Googol and Googolplex - Numberphile" - https://www.youtube.com/watch?v=8GEebx72-qs

The difference is that Pi is apparently normal, up to all extensive existing evidence. The Universe is not normal. Anyway, Physics doesn't preclude Helms Deep.
I think normalness is a stronger property than "possesses all sequences of the alphabet of its digits", since it means that + "all subsequences are equally likely"
