Theoretical Physics [OT thread]

"Kimball: I love it when engineers talk physics. It adds humor to my day..."

Hmm, us engineers love it when scientists try to talk about theoretical impossibilities. Nothing has yet proven to be impossible. Flying? Nope, done that. Speed of sound? Nope, done that too. Flat Earth? Heh, yeah right. The moon? Yep, been there. Weightless environments near the surface of the Earth? Thats old news. Some day we will be saying the same thing about going faster than c.
Some things I would never hope for, though, are time travel (throws all conservation laws out the window, while creating fantastic paradoxes), getting 'out' of a black hole (you have a spec of dust that was your space ship, try getting that out of infinite gravitational force), and creating matter/energy (how do you create something from absolute nothing?).
