16:33 Phys.org Information energy accounts for dark energy, resolves Hubble tension, avoids the 'big chill,' and is falsifiable

Stellar heated gas and dust has an entropy, or information content, with an equivalent energy of 1070 joules, directly comparable to the mc2 equivalent energy of the universe baryon mass. In a study published in Entropy, Professor Paul Gough at the University of Sussex shows that this information energy can account for the dark energy causing the accelerating universe expansion.

A trio of astrophysicists, two from Princeton, the other from New York University, has calculated estimations on how soon the universe could collapse if theories regarding dark energy as having quintessence are correct. In their paper published in Proceedings of the National Academy of Sciences, Cosmin Andrei, Anna Ijjas, and Paul Steinhardt suggest it could be as soon as 100 million years from now.

18:51 Phys.org Dark energy: Neutron stars will tell us if it's only an illusion

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, using Einstein's theory. But what if dark energy was just an illusion and general relativity itself had to be modified? A new SISSA study, published in Physical Review Letters, offers a new approach to answer this question. Thanks to huge computational and mathematical effort, scientists produced the first simulation ever of merging binary neutron stars in theories beyond general relativity that reproduce a dark-energy like behavior on cosmological scales. This allows the comparison of Einstein's theory and modified versions of it, and, with sufficiently accurate data, may solve the dark energy mystery.

The Dark Energy Spectroscopic Instrument (DESI) has capped off the first seven months of its survey run by smashing through all previous records for three-dimensional galaxy surveys, creating the largest and most detailed map of the universe ever. Yet it's only about 10% of the way through its five-year mission. Once completed, that phenomenally detailed 3D map will yield a better understanding of dark energy, and thereby give physicists and astronomers a better understanding of the past—and future—of the universe. Meanwhile, the impressive technical performance and literally cosmic achievements of the survey thus far are helping scientists reveal the secrets of the most powerful sources of light in the universe.

A spectacular portrait of the galaxy Centaurus A has been captured by astronomers using the Dark Energy Camera mounted on the Víctor M.

This galaxy's peculiar appearance—cloaked in dark tendrils of dust—stems from a past interaction with another galaxy, and its size and proximity to Earth make it one of the best-studied giant galaxies in the night sky.
