What we call laws of physics were made somewhere around the very beginnings of the big bang I'm told and that our universe could very well be just one of an infinite number of universes with an infinite number of different laws of physics and an infinite number with the same laws, and an infinite number where all of us are having this same discussion and saying exactly the same thing(parallel universes).
Smaller size infinities within bigger infinities, infinities up the yin yang/wazoo.
Or maybe this universe is just a high tech quantum computer simulation in the room of some pimply face adolescent kid who in turn is in a computer simulation and as Buzz Lightyear would say this goes on "to infinity and beyond."
