Why Stephen Hawking’s Black Hole Puzzle Keeps Puzzling
...who died today at 76, was something of a betting man, regularly entering into friendly wagers with his colleagues over key questions in theoretical physics. “I sensed when Stephen and...
He Seeks Mystery Magnetic Fields With His Quantum Compass
...It’s not an accident. There are several special things about diamonds that make them great for quantum physics. Humans love diamonds because diamonds are transparent and sparkly, which is related...
How Big Can the Quantum World Be? Physicists Probe the Limits.
...as motionless as the laws of physics permit. Two teams of researchers, in Austria and Switzerland, have independently succeeded in freezing such minuscule nanoparticles, just 100 to 140 nanometers across,...
Closed Loophole Confirms the Unreality of the Quantum World
...for anti-realism at the level of the quantum. But in May, Rafael Chaves and colleagues at the International Institute of Physics in Natal, Brazil, found a loophole. They showed that...
How a Biofilm’s Strange Shape Emerges From Cellular Geometry
...this emergence that attracted the biophysicist Peter Yunker to the microbial structures. Trained in soft matter physics — the study of materials that can be structurally altered — he is...
Quantum Leaps, Long Assumed to Be Instantaneous, Take Time
...an internal matter of physics, as one of its relation to philosophy and human knowledge in general.” In other words, there’s a lot riding on the reality (or not) of...
Physicists Peer Inside a Fireball of Quantum Matter
...information,” said Tetyana Galatyuk, one of the 200 members of the HADES collaboration. The experiment, reported this week in Nature Physics, is the first to measure the temperature of quark...
The New Thermodynamic Understanding of Clocks
Studies of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself. In 2013, a masters student in physics named...
How Quantum Physicists ‘Flipped Time’ (and How They Didn’t)
...computers, and Zeilinger’s work on the phenomenon won him a share of the 2022 Nobel Prize in Physics. For the flippable nature of quantum time, Franke-Arnold said, “it’s very early...
