On searches for antimatter in space… The observed domination of protons, neutrons and electrons over their antiparticles means that our universe has got the so called baryon quantum number. This is composed of baryon numbers of each of nucleons. It … Continue reading
How the decay of particles overtook that of antiparticles… It is observed that the number of baryons in the universe (protons and neutrons) exceeds the number of antibaryons at least ten thousand times. Such an asymmetry could arise in the … Continue reading
How lucky we are that in a changing world there is a stable proton… As we know, atomic nuclei of substance consist of nucleons — protons and neutrons. If the nucleons decay to other, lighter elementary particles, those will quickly … Continue reading
