Re: Backwards Time-travel

Suppose that someday we do find out how to travel back into the future. That would imply that we are currently being visited by ourselves from the future and affecting our future path. The key to discovering how that travel works, we must recognize any outside force guiding us now. Is that really intuition? Or our own voices echoing back upon us? And if so, where was (the future) I when I agreed to that reverse mortgage?

I just blew my own mind. I knew I'd say that.

The statement the "we could all be geniuses" gave me a chill! (I don't necessarily disagree with your point, just the idea of where it could/would lead).

Of course we can't all be geniuses. Especially through engineering. Remember Huxleys Brave New World and the engineering to make SOME of us geniuses, some of us of regular intelligence and some of us drooling morons suitable for only the most menial of labor. Way too plausible for me.

Pass the Soma, please.

: From Bill Brysons *a short history of nearly everything. Page 219 "The outer core (of Earth) is in many ways even less well understood, though everyone is in agreement that it is fluid and that it is the seat of magnetism. The theory was put forward by E.C. Bullard of Cambridge University in 1949 that this fluid part of the Earth's core revolves in a way that makes it, in effect, an electrical motor, creating the Earths magnetic field. The assumption is that the convecting fluids in the Earth act somehow like the currents in wires. Exactly what happens isn't known, but it is felt pretty certain that is is connected with the core spinning and with its being liquid. Bodies that don't have a liquid core - the Moon and Mars, for instance - don't have magnetism." Great book that is slowly turning me into more and more of a geek, page by page. I highly recommend reading it. Under good lighting, without breaking the spine.
