Good to know: no time travel.

But that deals with quantum phys-- ooh, shiny objects.

Think about it this way, though. We know that the Flux Capacitor works in one universe, and doesn't cross through them. We see this demonstrated when Doc writes that letter for Marty and Marty gets it hundreds of years later or whatever. Either the person achieves their task in this universe and falls into a paradox, or they find a way to open a wormhole to another universe where they complete their task, but they don't get the satisfaction of people in their home universe knowing what they did. Also, going from universe to universe damages the integrity of the space/time continuum, if I recall correctly.

Also, I don't think you'd want to create a NEW universe. That might be kind of hard. Now, you COULD access a parallel universe, which would be a much more viable and achievable option. In that case, I'll let you use my garage (I'm convinced there's a quantum hole somewhere, my mom hit her rear view mirror on the edge of the door, some plastic flew off and then the chip disappeared and the mirror was fine).
