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.
