Good idea. I support it.

Antimatter does not have a negative mass. that is impossible...
Antimatter means the protons (anti-protons) are negative and the electrons (positrons) are positive. The gravitational properties are unknown as there is too little in existence to tell. Logic would say that if in a vacuum, it would follow all other matter... down. (if not in a vacuum, then it would explode when in contact with matter)

(its mainly the subatomic charges. e.g. in beta decay, sometimes the beta decay is positve, and instead of a proton and an electron forming from a neutron, a anti-proton and a positron forms.)

Yeah..... I am neutral right now. (+0). Btw, @iliketurtles get a turtle account picture!

It would be a nice effect, but unrealistic.

Beta radiation is actually considered to have a negative mass, although so is an electron, which is the same as beta radiation. If you remember what you were thinking of, feel free to tell us.

Matter can have negative energy it's just I would have to be below 0K

Which is theoretically impossible, but if theoretically possible, you would be correct
