'There is no conflict between quantum physics and gravity': Physicists sent 20,000 atoms into free fall to prove Einstein's 'happiest thought' (opens the original)
Read excerpt
For the first time, physicists have measured the tiny quantum shift an object acquires by falling through Earth's gravity — an effect of Einstein's relativity that was predicted almost a century ago but never observed. Researchers placed ultracold rubidium atoms into a superposition, a quantum state in which a single particle takes two paths at once. In this experiment, one path put the atom in free fall while the other kept it motionless. Recombining the atoms revealed an almost imperceptible d
Astronomers spot the closest, fastest star ever seen orbiting our galaxy's monster black hole (opens the original)
Read excerpt
Astronomers have discovered the closest, fastest star ever seen orbiting Sagittarius A* (Sgr A*), the 4.3 million-solar-mass black hole at the heart of our galaxy. The faint star, named S301, completes a lap every 8.7 years and skims past the black hole at roughly 55 million mph (90 million km/h) — about 8% the speed of light. Its orbit is so tight that, within about a decade, researchers should be able to measure its spin rate. The discovery was reported Aug. 19 in the journal Nature. The cente
'Smaller than the tiniest scale in nature': Physicists made a black hole out of light and used it to test Stephen Hawking's elusive radiation theory (opens the original)
Read excerpt
Physicists have coaxed a black hole's most famous glow out of a strand of optical fiber and, for the first time, watched that light react back on the simulated black hole that produced it. The result gives researchers a rare, hands-on look at Hawking radiation — the faint thermal emission that Stephen Hawking predicted should leak out of black holes — and offers a first clue about the tiny push that could, in principle, make a real black hole slowly evaporate, the research team said in a new
'A new way to study the edge of a black hole': Physicists just got the closest-ever look at a black hole's event horizon (opens the original)
Read excerpt
Physicists isolated the 'last sound' of an enormous black hole collision, providing an unprecedented glimpse of the region next to the event horizon.
'What we found was striking': Physicists detect new kind of signal from a black hole's 'point of no return' (opens the original)
Read excerpt
Scientists have found evidence that gravitational waves from a spectacular black hole collision carry signals from the very edge of the newly formed black hole. If confirmed by future observations, the discovery could provide an entirely new way to investigate what happens in the immediate vicinity of a black hole without ever observing it directly. In a new study, the researchers analyzed an exceptionally strong gravitational wave event known as GW250114. They identified a "direct wave," a subt
