Majorana fermion: Physicists observe elusive particle that is its own antiparticle
Princeton University scientists have observed an exotic particle that behaves simultaneously like matter and antimatter, a feat of math and engineering that could yield powerful computers based on quantum ...
Every black hole contains a new universe: A physicist presents a solution to present-day cosmic mysteries
Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored ...
UCF physicist says Hollywood movies hurt students' understanding of science
Movies such as Spiderman 2 and Speed generate excitement among audiences with their cool special effects. But they also defy the laws of physics, contributing to students’ ignorance about science.
Negative Refraction of Visible Light Demonstrated; Could Lead to Cloaking Devices
For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water or glass. The phenomenon ...
Time to overhaul Newton's theory of gravitation? Galaxy cluster models cast doubt on dark matter
For almost 75 years, astronomers have believed that the Universe has a large amount of unseen or ‘dark’ matter, thought to make up about five-sixths of the matter in the cosmos. With the conventional theory of gravitation, ...
Do classical laws arise from quantum laws?
V-shaped solar cells could lead to better efficiency
Rapid-fire: Electrical circuit may bring Sandia Z to fusion sooner
An electrical circuit that should carry enough power to produce the long-sought goal of controlled high-yield nuclear fusion and, equally important, do it every 10 seconds, has undergone extensive preliminary ...
The New New Math of String Theory
At the beginning of the last century, Albert Einstein posited a now famous theory that forever linked geometry and fundamental physics. According to general relativity, spacetime is curved, and that curvature ...
Maybe it wasn't the Higgs particle after all
Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.
Gravity may have saved the universe after the Big Bang, say researchers
(Phys.org) —New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang.
Hubble Telescope Finds Ring of Dark Matter
US astronomers on Tuesday presented the most solid proof yet of the existence of dark matter, a mysterious substance believed to make up more than a quarter of the universe.
Particle X in rare decay could belong to a new physics model
Physicists reveal water's secrets
It's essential to all life, and numerous research papers are published about it every year. Yet there are still secrets to reveal about water, that seemingly simple compound we know as H2O.
