Best of Last Week – Two mysterious bursts from space, new developments with batteries and fingertip reader for the blind
Einstein's gravity theory passes toughest test yet: Bizarre binary star system pushes study of relativity to new limits
(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive ...
Pair of noted physicists contemplate future of cosmology after detection of primordial gravitational waves
Researchers propose a new way to detect the elusive graviton
(Phys.org) —Among the four fundamental forces of nature, only gravity has not had a basic unit, or quanta, detected. Physicists expect that gravitational force is transmitted by an elementary particle called a graviton, ...
Quantum measurement precision approaches Heisenberg limit
Blogger claims BICEP2 team acknowledging possible error in discovery of evidence of gravitational waves
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Could Exotic Matter Provide an Infinite Source of Energy?
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.
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 ...
Gravitational waves help understand black hole weight gain
Supermassive black holes: every large galaxy's got one. But here's a real conundrum: how did they grow so big?
Planets can form in the galactic center
(Phys.org)—At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. Stars crowd each other as they whiz through space like cars on a rush-hour freeway. ...
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 ...
'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.
