If you're talking about what I was talking about with the negative energy thing, you're completely wrong. Negative energy doesn't mean like +,- charges nor does it mean from matter or antimatter. Negative energy is just, well, wierd. It's the "debt" of energy. If a laser is going through a crystal, the waves make the energy at any point fluctuate, but the average remains the same. Thus to produce negative energy, you make the crystal amplify the fluctuations till at it's lowest, the amount of energy is negative, but it still has the same average so it deosn't violate any principles. Of course it's a little more complex than that, but that's one way of thinking about it/doing it.
Erm, a blackhole doesn't actually get rid of matter (well, it could turn it into energy, but that still isn't exactly destroying it), it just has infinate gravity so matter that reaches it is kept there. So, if a white hole is the exact opposite, it would have to create energy from nothing (which would violate the conservation of energy/matter) and have 0 mass. Hmmm, so why isn't empty space a white hole? Or would it be infinately negative mass? But then you said negative mass was like antimatter, and an infinate amount of antimatter still makes a blackhole. I wouldn't exactly always say that just because something in physics is true, its opposite is true.
PS Antimatter isn't just theoretical; it has been produced in laboritories.
