Hace 2 días · Another major theme of early universe cosmology is the methodological goal of finding dynamical explanations for striking features in the universe. Some examples of such a methodologyinclude the cosmic arrow of time, posits of a Past Hypothesis for the initial state of the universe, inflation, baryogenesis, and emergence of spacetime.
Hace 4 días · The discovery provides a significant update to the universe’s origin story as previously told using data from NASA’s Hubble Space Telescope. Studying distant galaxies with JWST gives Guo, Kuhn and other scientists an opportunity to solve a cosmic puzzle by determining the meaning of each clue.
Hace 5 días · It is puzzling how the black hole at its center could already weigh a billion solar masses when the universe was still in its infancy. The James Webb observations were designed to take a closer look at the feeding mechanism, but they found nothing out of the ordinary.
Hace 5 días · We present a type IIB 4D string model with stabilised moduli which is able to describe the history of the universe from inflation to quintessence. The underlying Calabi-Yau volume is controlled by two moduli which are stabilised by perturbative effects. The lighter of them drives Fibre Inflation at a large energy scale. The two associated axions are ultra-light since they are lifted only at ...

Hace 4 días · On the largest of cosmic scales, the Universe is expanding. But it isn’t all-or-nothing everywhere, as “collapse” is also part of the story. At the start of the hot Big Bang, the Universe ...
