Theorist suggests a way to test gravitational Casimir attraction
Researchers conduct first direct measurement of gravity's curvature
NuSTAR sees rare blurring of black hole light
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the ...
Researchers figure out how oddly shaped sandstone landform structures come about
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 ...
With neutrons, scientists can now look for dark energy in the lab
It does not always take a huge accelerator to do particle physics: First results from a low energy, table top alterative takes validity of Newtonian gravity down by five orders of magnitude and narrows the ...
Gravity measurements confirm subsurface ocean on Enceladus
In 2005, NASA's Cassini spacecraft sent pictures back to Earth depicting an icy Saturnian moon spewing water vapor and ice from fractures, known as "tiger stripes," in its frozen surface. It was big news ...
Researchers propose method for measuring gravitational impact on antimatter
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
A brighter method to determine surface gravity of distant stars
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Did Andromeda crash into the Milky Way 10 billion years ago?
(Phys.org) —For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbour, the Andromeda Galaxy, in about 3 billion years' time and that this will be ...
Researchers suggest gas cloud could reveal black holes near center of Milky Way galaxy
Team solves the origin of the Moon's 'mascons' mystery
A mystery of the moon that imperiled astronauts and spacecraft on lunar missions has been solved by a Purdue University-led team of scientists as part of NASA's GRAIL mission.
