Black holes are formed due to the gravitational collapse of matter – ordinary matter, consisting of the particles and excitations of the Standard Model that we know and love. These include electrons, photons, neutrinos, quarks, mesons etc, and their respective anti-particles. General Relativity tells us that the properties of (macroscopic) black holes are universal, in… Continue reading Elementary particles and quantum geometry
