Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative hypothesis, showing how gravity could exist without mass and produce many of the same effects we ascribe to dark matter.Continue ReadingCategory: Physics, ScienceTags: Astronomy, Dark Matter, Gravit

Quantum helium tornado in lab mimics black holes' warped spacetime
Posted by ArielTechGeek 231 days ago (https://newatlas.com)
As anyone who's ever seen a science fiction movie knows, whipping up a black hole in a laboratory doesn't seem like such a good idea.Continue ReadingCategory: Physics, ScienceTags: Space exploration, Black hole, Quantum Physics, Helium, University of Nottingham, King's College London, Newcastle University, Superfluid
Hunting spacetime fluctuations could unite Einstein and quantum physics
Posted by ArielTechGeek 338 days ago (https://newatlas.com)
A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and importantly, outlines a way to test it experimentally.Continue ReadingCategory: Physics, ScienceTags: Gravity, Quantum Gravity, Albert Einstein, University College London, relativity, Quantum, Quantu
LIGO squeezes light to surpass quantum limit measuring spacetime ripples
Posted by ArielTechGeek 380 days ago (https://newatlas.com)
Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of existence. Now the LIGO facility has pushed beyond this quantum limit by “squeezing” laser light, which will boost gravitational wave detections by about 60%.Continue ReadingCategory: Physics, ScienceTag
Galactic-scale detector picks up background distortions in spacetime
Posted by ArielTechGeek 493 days ago (https://newatlas.com)
The very fabric of spacetime is constantly warping, on unimaginably tiny scales, as ripples from past cataclysms wash over us. Astrophysicists have now detected a background sea of gravitational waves, using a galaxy-scale detector made up of dead stars.Continue ReadingCategory: Space, ScienceTags: Astronomy, Astrophysics, gravitational waves, Physics, Black hole, Supermassive black hole, LIGO, C
Mutual destruction: Binary stars, black holes, and ripples in space-time
Posted by ArielTechGeek 559 days ago (https://newatlas.com)
Researchers from University College London and the University of Potsdam, Germany have studied two most massive touching stars in a neighboring galaxy that will eventually turn into black holes and collide, sending ripples through space and time.Continue ReadingCategory: Space, ScienceTags: Stars, Multiple stars, Black hole, gravitational waves, University College London, University of Potsdam
