More of a problem: the edge of the observable universe is simply the edge beyond which light hasn't yet reached us. If the universe is flat and infinite (as it currently appears to be) then in a universe with an infinite speed of light there would be no edge to the observable universe. We would see everything, and the whole night sky would shine like the sun. This would seem to be a hindrance. edit: On the other hand if the universe just wraps around, then... actually I'm not sure what happens, but I guess every ray of light emitted from a star gets absorbed by something, which would still make the Earth (if planets could even exist) far too hot.
