Cosmic Voids: Where Dark Energy Dominates and Drives Universe Expansion

Cosmic voids, the vast empty regions between galaxies and cosmic structures, appear devoid of matter, radiation, dark matter, and other components. However, they are not truly empty.

New Method Uses Gravitational Waves to Improve Measurements of the Universe’s Expansion

Astronomers have long known that the universe is expanding, but the exact rate of expansion, measured by the Hubble constant, remains a mystery. Multiple methods used to calculate this constant have…

Dark energy survey scientists release analysis of all six years of survey data

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the universe's expansion history that are twice as tight as past analyses.

Universe's expansion 'is now slowing, not speeding up'

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkab...

Could Earth Be Inside a Vast Cosmic Bubble? New Study Suggests So

Scientists suggest Earth and the Milky Way may reside in a vast cosmic void, potentially resolving discrepancies in measuring the universe’s expansion rate. 🌌 #CosmicVoid #HubbleTension #UniverseEx…
