does negative mass exists?
actionintegral said:An antiparticle would have a negative rest mass
superweirdo said:but we aren't sure that antiparticle exists either. As far as I know, the only reason we even believe in antiparticles is b/c of them, we laws make sense b/c when you exclude them from theory, our physics seems flawed, still a lot of physicist don't believe in it though coz we don't have a brute evidence for it.
We are sure they exist. CERN even has an antimatter factory. :!)superweirdo said:but we aren't sure that antiparticle exists either.

actionintegral said:According to the feynman's theory of positrons, the proper time for an antiparticle the reverse of the proper time for matter. The proper mass would be reversed as well. All invariant quantities would be reversed for
antiparticles.
actionintegral said:Hi Norman,
Sorry to appear obtuse, but once I learned that antiparticles were reversed in time, I jumped to the conclusion that all invariant quantities were reversed for antiparticles. Please follow me to the QM forum where I
re-posed my question.
superweirdo said:I didnt even know that antiproton exist, I guess I shouldn't argue you guys about these things, so far, I am only aware of 3 anti things, antimatter, antiparticle, and anti proton. Are there anymore?
superweirdo said:What you said completely made sense to me selfadjoint but the analogy you gave didn't sound right to me, rather I'd like to use the analogy that every equation has an inverse but for the equation that don't, here though, their inverse is the same equation.(this isn't mathematically correct but seems more logical to me)
btw, I also heard something about antiparticles that they have inverse time and space(guessing this one) too which didn't make sense to me, could you guys explain this to me?
Being meaningless, that's a question that can not be answered.superweirdo said:so you don't believe that it have has inverse time and maybe space?
superweirdo said:I am not sure if I follow your metaphor Gokul.

Sure. Seeactionintegral said:There is an old paper by Bondi about negative mass. Since I only have negative money, can someone send it to me?
Rade said:A recent paper that "suggests" possibility of negative mass--someone needs to verify the math:
