Thanks, I got the new Discover magazine right next to me. "the New Rules of Time Travel"
note to self....buy it
from what i remember from old discover mags is either
1) find 2 gravity waves (created at the big bang) moving in the opposite direction and loop de loop them
2) find a black hole connected to another black hole thru a worm hole and travel thru without getting smooched by gravity
3) traval at the speed of light or close to it for a while
