The researchers found the result by studying a tiny, jiggling membrane. Their experiment could lay the groundwork for further tests of the laws of thermodynamics at the tiniest scales.
From the forces that keep athletes twirling and sliding, to the weird laws governing the world of the very small, to the far-out concepts of time travel and alternate universes, physics covers a lot of interesting territory. Here, Live Science keeps you abreast of all the fascinating physics discoveries.Physics
The micron-sized drum apparatus used by the two teams has applications from probing for quantum gravity to building the first quantum computers.
A rare type of plutonium has been found in the crust below the deep sea, offering new clues as to how heavy metals form in star explosions and mergers.
Imaginary numbers have real meaning in the world of quantum mechanics, where they carry information about physical states.
Physicists have long been unable to describe what happened just after the Big Bang when a teensy blip ballooned into the universe, a process called inflation. We may know why.
Space junk is a growing problem. Scientists want to fight it with lasers that can de-twinkle the stars.
A never-before-seen particle known as the odderon has revealed itself in the hot guts of two particle colliders, confirming a 48-year-old theory.
The first-ever images of a magnetic field around a black hole may explain the jet of matter and energy emanating from the center of galaxy M87.
The weird behaviour of the beauty quark has led physicists to believe it could be a window to a completely new physics.
Back in 2017, a point of strange light flashed through the solar system. Three years later, a new team of scientists claims to have figured out what it was.
A supermassive black hole is racing across the universe at 110,000 mph (177,000 km/h), and the astronomers who spotted it don't know why.
The hypothetical Planet Nine may not be a planet but rather a small black hole that might be detectable from the theoretical radiation emitted from its edge, so-called Hawking radiation.
The most remote particle detector on Earth has detected the most energetic antimatter neutrino ever, confirming a 51-year-old prediction.
