Jamika Gregorio: I believe the conservation of matter can be split up into several other conservations such as the conservation of baryon and lepton numbers. As these are negative for antiparticles, conservation is still achieved, I hope this makes sense. But overall, matter is conserved as technically there was zero to start with as half of the matter involved was "negative matter".
Shena Etulain: ever since the realization that matter and energy are convertiblespecifically E = m c^2we have had to say thatthe sum total of matter and energy as connected by E = m c^2 is constant.the laws of conservation of energy and mass have mergedIf someone gives you a good response, please consider giving a best answer.This is the only reward we get....Show more
Davina David: Actually not so. Both the conservations, momentum and energy, apply. Don't forget that mass, as in matter and anti matter, is nothing more than stored energy according to e = mc^2.So, as the two part! icles are the same mass, m, we have a total energy E = 2e = 2mc^2 for the two. And, ta da, when they couple and annihilate into a photon we have E = 2e = 2mc^2 = hF = E where E = hF is the energy of the photon with frequency F.You can find F = 2e/h = 2*.511E6/4.13E-15 = 2.4746E+20 cps for the resulting photon when an electron and positron couple, each with e = .511E6 eV of rest mass energy. Gamma ray frequency is roughly 1E23 cps; so the resulting photon would be a tad less than gamma ray energy....Show more
