Absence of gravitational-wave signal extends limit on knowable universe
Imagine an instrument that can measure motions a billion times smaller than an atom that last a millionth of a second. Fermilab's Holometer is currently the only machine with the ability to take these very ...
New insights found in black hole collisions
New research provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger black hole.
Theorist suggests a way to test gravitational Casimir attraction
Planck: Gravitational waves remain elusive
Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial ...
Tabletop experiment could detect gravitational waves
(Phys.org)—A coin-sized detector might observe gravitational waves before the giant Laser Interferometer Gravitational-Wave Observatory (LIGO), according to two Australian physicists.
Not much force: Researchers detect smallest force ever measured
What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. Using ...
Black hole trio holds promise for gravity wave hunt
The discovery of three closely orbiting supermassive black holes in a galaxy more than four billion light years away could help astronomers in the search for gravitational waves: the 'ripples in spacetime' ...
Big Bang breakthrough team allows they may be wrong
American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong.
New research shows that gravitational fields around black holes might eddy and swirl
Fasten your seatbelts – gravity is about to get bumpy. Of course, if you're flying in the vicinity of a black hole, a bit of extra bumpiness is the least of your worries. But it's still surprising. The ...
