If we produced it in large quantities we'd blow our world out of existance. I don't think we can be trusted with such godly power yet. Antimatter bombs would make nuclear bombs look like m80s.
Really? That's interesting, I've never heard that before. Why would splitting (or fusing?) an anti-nucleus (?) cause such a massive reaction? Are large enough anti-particles even known? I thought the only one we've created is antihydrogen?
