[QUOTE="chilibean, post: 141247, member: 2220"] The theory of relativity has no place in a fantasy setting with magic. For those that wish to think up devastating weapons from bizarre combos of D&D magic and real physics, make a gate that unattended objects can pass through freely, but not gravity. Then simply open it to the center of a blackhole or a neutron star. The infintely small black hole would simply pass through the gate and consume the entire world and surrounding solar system. The neutron star would create an explosion of almost incalculable power (depends on the size and duration of the gate). Suppose that you time/space warp exactly 1 second into the past to a distance 1 light second away rotated 180 degrees around. The light bouncing off of you would exactly reach "yourself" at the moment you warped. Then, it would warp back with you, and travel to hit yourself again. And again. And again. So the same photon traveled the same distance an infinite number of times. An outside observer would thus see a beam of infinite photos (& thus infinite power) suddenly appear between 2 points 186 thousand miles apart. Since infinite energy has infinite mass and thus infinite gravity, the entire universe collapses onto the beam destroying the universe. :rolleyes: Sounds like something Raistlin would do ...
