Cosmology

A new analysis from Queen Mary University of London proposes that the universe's physical constants occupy a narrow range allowing liquids to flow properly inside living cells.

New analysis of gravitational wave data indicates that the universe's heaviest black holes arise from multiple collisions inside dense star clusters instead of single stellar collapses.

Astronomers have discovered that the Milky Way resides within a vast, flat sheet of matter dominated by dark matter, surrounded by enormous empty voids. This structure explains why most nearby galaxies are moving away from our Local Group rather than being drawn in by gravity. The finding, based on advanced simulations, resolves a longstanding puzzle in cosmology.

Researchers from the University of Illinois Urbana-Champaign and the University of Chicago have developed a novel approach to calculate the Hubble constant using gravitational waves from black hole collisions. This technique, known as the stochastic siren method, analyzes the background hum of faint mergers to potentially resolve the Hubble tension. The findings, accepted for publication in Physical Review Letters, offer improved precision with current data.
