Webb24 juli 2024 · Inflation itself is quite flashy: a short moment, in our part of the universe anyway, where space-time rapidly expands. Reheating, by contrast, is “just” the aftermath of inflation, when the universe is very cold and it needs to literally reheat and fill with the particles that form the structures we observe today, about 14 billion years later. WebbEternal inflation begets a multiverse One of the more startling predictions of a variety of inflationary models is the existence of domains outside our observable horizon, where the fundamental constants of nature, and perhaps the effective laws of physics more generally, vary (Guth 1981; Guth and Weinberg 1983; Steinhardt 1983; Vilenkin 1983;
