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 all the baryons except protons broke apart in the universe As there are no baryons lighter than a proton, its baryon charge would disappear if it decayed. For this reason, the proton lifetime is immeasurably greater than that of … 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
