For the first time ever, physicists see particles form through quantum tunneling: ScienceAlert
Chemistry takes effort. Whether by raising the temperature, increasing the odds of matching atoms colliding in a hot collision, or increasing the pressure and squeezing them together, building molecules usually requires a certain cost in energy.

Physicists Rewrite a Quantum Rule That Clashes With Our Universe
Ajarring divide cleaves modern physics. On one side lies quantum theory, which portrays subatomic particles as probabilistic waves. On the other lies general relativity, Einstein’s theory that space and time can bend, causing gravity. For 90 years, physicists have sought a reconciliation, a more fundamental description of reality that encompasses both quantum mechanics and gravity. But the quest has run up against thorny paradoxes.

Physicists Say Aliens May Be Using Black Holes as Quantum Computers
If life is common in our Universe, and we have every reason to suspect it is, why do we not see evidence of it everywhere? This is the essence of the Fermi Paradox, a question that has plagued astronomers and cosmologists almost since the birth of modern...

'Negative mass' created at Washington State University
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards. The phenomenon is rarely created in laboratory conditions and can be used to explore some of the more challenging concepts of the cosmos, said Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington.

Why More Physicists Are Starting to Think Space and Time Are ‘Illusions’
A concept called “quantum entanglement” suggests the fabric of the universe is more interconnected than we think. And it also suggests we have the wrong idea about reality.

Physicists have used entanglement to 'stretch' the uncertainty principle, improving quantum measurements
Examining microscopic quantum objects is exceedingly tricky, because their properties are connected to each other. But there could be a new method to measure them as accurately as possible.

A Powerful Recoil Effect Magnified NASA’s Asteroid Deflection Experiment
Scientists continue to pore over the results of NASA’s stunningly successful DART test to deflect a harmless asteroid. As the latest findings suggest, the recoil created by the blast of debris spewing out from Dimorphos after impact was significant, further boosting the spacecraft’s influence on the asteroid.

Breakthrough wormhole simulation may unite quantum physics and general relativity
Scientists have devised a quantum experiment that allows them to study the dynamics of wormholes, theoretical spacetime entities that first emerged from Albert Einstein's 1915 theory of gravity, or general relativity.

High-Temperature Superconductivity Understood at Last
For decades, a family of crystals has stumped physicists with its baffling ability to superconduct — that is, carry an electric current without any resistance — at far warmer temperatures than other materials. Now, an experiment years in the making has directly visualized superconductivity on the atomic scale in one of these crystals, finally revealing the cause of the phenomenon to nearly everyone’s satisfaction. Electrons appear to nudge each other into a frictionless flow in a manner first suggested by a venerable theory nearly as old as the mystery itself.

Does Quantum Entanglement Allow for Faster-Than-Light Communication?
Quantum entanglement allows particles to affect one another faster than the speed of light. So does this mean we could one day build a device to exploit this and enable superluminal communication? A popular trope in sci-fi for sure, but today let's look at the science.

Ignition confirmed in a nuclear fusion experiment for the first time
We have ignition. An analysis has confirmed that an experiment conducted in 2021 created a fusion reaction energetic enough to be self-sustaining, which brings it one step closer to being useful as a source of energy.
