‘Cosmic Glitch’ could explain why gravity acts differently across the Universe
Einstein’s theory of gravity may behave slightly differently across distances of billions of light-years, with gravity appearing about…
Cosmic plasma was supposed to rule out dark photons. Simulations say otherwise
A major limit on dark photon dark matter may be far weaker because early-universe plasma stops absorbing energy…
The Milky Way glows brightly in first-of-its-kind neutrino image
IceCube has produced the first neutrino image of the Milky Way, revealing high-energy particle activity concentrated along our…
New study challenges existing knowledge for why galaxies stop forming stars
Most galaxy collisions do not cause galaxies to stop making new stars. A galaxy’s central black hole and…
Mathematician Offers New Solution to a Fundamental Cosmic Paradox
A thermodynamic analysis of spacetime also points to an unexpected role for emergent dark energy and hints that…
Dark matter may be naturally tuned to a hidden fifth dimension
Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests…
Decades-Old Dark Matter Explanation Fails Its Most Direct Test Yet
A decades-old dark matter claim is facing a decisive new challenge. The result clears the way for future…
New study reveals how dark matter formed shortly after the Big Bang
Dark matter may not have needed a calm, cold start to help build the universe. For decades, that…
The universe isn’t as uniform as we thought
Modern cosmology rests on a simple assumption: if we look on large enough scales, matter should be distributed…
Astronomers discover faint dwarf galaxy that seems to exist without dark matter
A faint dwarf galaxy drifting 45 million light-years from Earth may have joined one of astronomy’s strangest clubs.…
