Actually, no, the only site I visited on this speculation for neg-matter was the Wiki-site, and that was only after the conception of such a kind of
Oh, I didn't mean to say that neg-matter was made of tachyons, but that tachyons could be part of what we term "neg-matter".
Now, I remember hearing things from other people on the subject of tachyons, such as that - going faster than light - they may also travel backwards
through time, rather than forwards. If the tachyon can be seen as a fundamental particle of neg-matter (in the same regards as electrons), then in
essence neg-matter could be travelling backwards in time as well.
I don't want to dip into reverse time-travel though, as it means something's happening in the future to affect the past. If time itself were
reversed, then that's fine, but from our perspective you can't change the past, and so such a concept is mind-bending in order to comprehend or
In any case, I'm glad to hear that neg-matter is something that other people have thought of.
Oh, and Doc, you're not entirely right, but not entirely wrong
. Neg-matter is, yes, still affected by gravity. If neg-matter doesn't travel
faster than light, then a piece of neg-matter in an elevator, so long as the neg-matter is less "massive" than the mass beneath it, would still sit
at the bottom of the elevator.
However, as the neg-matter has a "neg-mass" approaching that of the mass beneath it, then it would start doing really funny things. First, even
before we really notice anything different, the neg-matter would be lighter than it should be, even if the substance itself were very dense (funnily
enough, the denser the neg-matter would be, the LIGHTER it would become! I just thought of that - how odd). Then, as it truelly approaches it, the
neg-matter would start to fly. This wouldn't be because it is repelling the regular matter (which it is - just not to a high enough degree yet), but
because it's become lighter than the air around it. Even if it floats to the top of the elevator, it still wouldn't affect the elevator itself.
However, that would change once the neg-mass exceeds the reg-mass. It would start pushing away, and would start carrying the elevator along with
Now, an important thing to consider here is that Gravity ISN'T a push or a pull. It's a space-time warp. We fall because, in our paper-sheet
conception, the paper slopes inwards, and then gravity draws it down. Really, even though it slopes inwards, it's the path that the object is taking
that is changed, it's not actually being pulled down. The same with the neg-mass, which has a slope that would bulge out from the paper. It's not
pushing things away from it, it's just changing the path that something is taking and the path leads away from it.
Summarization: The rules of general relativity, and the consequences of exotic types of matter, are really wierd.
Summary of the Summary: The universe is wierd.
