Heh heh, another science freak in our midst. Monkey likes. As to the concept of multiple infinities, there is actual notation to show the level of infinity (yeah, there is math for that). I'd have to dig out one of my books or Wiki it.
The computer simulation question goes way back to philosophers wondering if we are just the product of someone's dream. Fascinating idea on how would you prove that we are not in a definitive reality? Remember the end of Men in Black with the universes in marbles within other universes? Run with that, and then we come up with- what is reality?
Saw a show the other day about the Bermuda Triangle. They tried to sink a sailboat but blowing bubbles up at it from below (the methane explosion theory), but basically nothing happened. They got it to sink once they loaded it with 5000 pounds of bricks. Then they worked on planes- could lightning ignite a fuel tank. Oh, hell yeah! I think the show is called "Curiosity," though I could be wrong
I can't wait for the hard science shows to start up again.
