From: "I am only an egg." <JOHNSON@nuhub.acs.northeastern.edu> I'm not sure I believe in time travel and I don't believe in historical paradoxes because there aren't any as far as I can observe. However, I saw the _Philadelphia_Experiment_ on cable again the other day. Here's how I thought it might have worked. You need two *bubbles* of our space-time into hyperspace, or whatever, that overlap (whatever that means) in hyperspace. One of hem is at one *point* in space-time and one at another *point* in space-time. The overlap of the two extensions of our space-time forms a corridor *around* what we perceive as time. Real objects can pass through the corridor effectively from one *time* to another. The catch here is that you *need* two of these hyperspacial bubbles set up for the corridor to happen. Just one won't do it. Maybe there isn't enough energy in the universe for one bubble to make it. We haven't built the bubble on this end of things yet so no time travel has been observed. Now, I'm probably going to get well warmed by the real physicists out there for building a *theory* from a sci-fi story and for again bringing up what should be a dead issue by now, but would someone care the explain why this idea won't work. I know you have to believe in hyperspace for this but the supersymetrists do already. Chris Johnson Northeastern University
