An Oxford Physicist Discovered Particles Doing the Impossible. It Could Finally Solve the Quantum Gravity Mystery.

3+ week, 1+ day ago   (147+ words) And lead to an understanding of how gravity and quantum mechanics can play together in the same universe. But is that really what happens? However, Hawking’s logic suggests that as evaporation continues beyond this point, still further entanglement must be…...

A College Student Accidentally Broke the Laws of Thermodynamics

1+ week, 3+ day ago   (323+ words) A magnetized mix of oil, water, and nickel particles created a never-before-seen state. As Homer Simpson once famously phrased, “in this house we obey the laws of thermodynamics,” but a completely unexpected discovery by a student at the University of…...

Spacetime May Be Just One Layer of the Universe—Embedded in a Deeper Reality We Don’t Understand

3+ week, 2+ day ago   (1725+ words) This means there could be much more to the universe than we ever expected. To remedy this, Mehta developed a framework that replaced what he regards as the mathematical “duct tape” of the earlier treatment with a mathematically rigorous description…...

Scientists Reversed a Law of Physics by Scrambling Cause and Effect

5+ day, 2+ hour ago   (326+ words) Indefinite causal order let physicists reverse a rule of nature, then confirm it with a split light beam. Explorations like this aim to bring quantum and classical physics closer to a unified theory of gravity. For instance, while ICO explains…...

Something Weird Happened That We Can’t Really Explain With Existing Physics

3+ week, 6+ day ago   (221+ words) Why did this particle mysteriously disintegrate? Scientists have proposed a new kind of subatomic particle to explain another particle’s mysterious disintegration. The kaon, a special case of meson particle, is made of one quark and one antiquark. All are part…...

Scientists Grew a Brain Cortex in a Lab for the First Time Ever

3+ week, 5+ day ago   (162+ words) This new organoid will provide valuable insight into how the brain—both mouse and human—develop in the body. The research gives scientists a good idea of which current brain organoids are good candidates for further study—and which aren’t....

There’s a Vast Network Beneath Your Feet—And It Could Be Conscious, Some Theories Claim

4+ week, 1+ day ago   (1714+ words) It’s so large that it could stretch from the sun to Pluto an unfathomable number of times. These AM fungi are essential for plants across the world, as they play a major role in their sustenance. For instance, mycorrhizal fungi…...

Scientists Just Made a Game-Changing Discovery: Diamonds Can Produce Electricity

1+ week, 3+ day ago   (295+ words) Scientists long thought this pricey piece of carbon held no piezoelectric properties, but a new study says that isn’t the case. And while that’s true for bulk diamonds, a team of researchers from the University of Hong Kong wondered if…...

Physicists Have Been Chasing a Mysterious Particle for 50 Years—and They May Have Just Found It

2+ week, 5+ day ago   (172+ words) X(2370) has long been a leading candidate for a “glueball”—a hypothetical particle made almost entirely of gluons. “The radiative decay of the J/ψ meson is a gluon-rich process and is therefore regarded as an ideal place for searching…...

Scientists Just Built a Fridge 180 Times Colder than Deep Space—It Could Unlock the Quantum Era

1+ week, 4+ day ago   (369+ words) • Quantum computers require extremely cold temperatures to maintain coherence, but creating a refrigerator big enough to scale with all the hardware and wiring isn’t easy. • IBM announced earlier this month the creation of a modular system that relies on dilution…...
