University of Ottawa researchers tested a 'tired light' model with changing physical constants against galaxy rotation, cosmic expansion and early-element formation.
Istanbul Technical University physicists say a teleparallel f(T) model produces a sign change about 9.5 billion years ago with no extra free parameters, matching the hints in DESI data.
The first test image shows stars as blurry rings, exactly as expected. Sharp pictures are still months away, and science operations are set for 2027.
For the first time the radio telescope detected the cosmic hydrogen signal using only its own data. That opens a cheaper, faster route to testing what dark energy really is.
In Physics of the Dark Universe, Shin'ichi Nojiri and Sergei Odintsov find that objects with negative mass can arise consistently in a universe filled with negative-pressure fluid or extra scalar fields, and could bend light the wrong way.
UC San Diego physicists built a way to separate detector errors from a real rotation of the cosmic microwave background's polarization. Applied to Planck data, it recovers a twist of 0.37 degrees, which could point to new physics.
The DESI Legacy Imaging Surveys released their 11th data set on Monday, covering roughly three-quarters of the sky. More than 160 scientists and four telescopes built it, and anyone can open it in a browser.
The Nancy Grace Roman Space Telescope lifted off on a Falcon Heavy at 7:26 a.m. on August 30. Its 300-megapixel infrared camera surveys the sky about 1,000 times faster than Hubble.
Yonsei University researchers say the June rebuttal to their work contains a methodological flaw that flattens the very effect it was measuring. Their corrected supernova results now line up with DESI.
A Leiden University team's 'Quantum Memory Matrix' theory suggests spacetime stores an imprint of every interaction, a single framework its authors say could also resolve the black-hole information paradox.
Theoretical study suggests massive stellar collapse might trigger birth of tiny cosmos driven by dark energy, forming exotic objects called gravastars.
Revolutionary gravastar theory suggests massive stellar collapse triggers miniature universe creation, challenging conventional black hole formation.
Researchers found that a controversial 2025 study made key mistakes when analyzing supernova data, confirming cosmic acceleration remains strong.
Scientists propose that massive stellar collapse might trigger the birth of a tiny cosmos inside the dying star.
Transfer learning dramatically reduces simulation costs for cosmological research, yet scientists warn the technique could overlook truly novel phenomena.
Accelerated timeline brings infrared observatory ahead of original May 2027 deadline to explore dark energy, dark matter, and exoplanets.
The Dark Energy Spectroscopic Instrument collaboration completed the largest high-resolution cosmic map ever created, ahead of schedule despite wildfire disruptions.
Scientists completed the largest high-resolution 3D map of the universe ever created, gathering unprecedented data that hints dark energy may behave in unexpected ways.
The observatory, scheduled for launch as early as fall 2026, carries a field of view 100 times wider than Hubble's to hunt dark matter, dark energy, and distant worlds.
New Year 2 data from 7.8 million galaxies shows dark energy may be evolving over time, adding to a growing tension with the prevailing Lambda-CDM model.
A Nobel laureate-led team at STScI measured the universe's expansion rate at 73.50 ± 0.81 km/s/Mpc using a new unified statistical framework, confirming beyond doubt that the 'Hubble tension' between early- and late-universe measurements cannot be explained away.
An unprecedented superluminous supernova, split into multiple images by a foreground galaxy, may help resolve the Hubble Tension
