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.

This is inspired by properties of a measure of time—the Chern–Simons time—and the fact that in some theories it appears …
Webb19 sep. 2024 · The inflationary scenario [ 1, 2, 3, 4, 5] is the current paradigm of early universe cosmology. In addition to explaining the homogeneity, spatial flatness and large size of our universe, the accelerated expansion of space provided by inflation yields a mechanism to explain the origin of structure in the universe [ 6, 7 ]. WebbInflation is generally thought of as an inordinate rise in the general level of prices. Four theories are commonly used to explain inflation. The first and oldest, the quantity theory, promoted in the 18th century by David Hume, assumes that prices will rise as the supply of money increases.
WebbEternal in ation [1] refers to the near de Sitter (dS) regime deep into the phase of in ation in which the quantum uctuations in the energy density of the in aton are large. In the usual account of eternal in ation the quantum di usion dynamics of the uctuations is modeled as stochastic e ects around a classical slow roll background. Eternal inflation is a hypothetical inflationary universe model, which is itself an outgrowth or extension of the Big Bang theory. According to eternal inflation, the inflationary phase of the universe's expansion lasts forever throughout most of the universe.
