The world's lowest noise laser: Researchers outsmart quantum physics
Researchers at the Max Planck Institute for Gravitational Physics and Leibniz University of Hanover have produced a laser beam of especially high quality. In doing so, they have achieved a new world record ...
A Matter of Fact: NASA Finds Direct Proof of Dark Matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct ...
Scientists find a practical test for string theory
(Phys.org) —Scientists at Towson University in Towson, Maryland, have identified a practical, yet overlooked, test of string theory based on the motions of planets, moons and asteroids, reminiscent of Galileo's ...
World's Largest Quantum Bell Test Spans Three Swiss Towns
Fusion scientist revives magnetic mirror machine with cool new idea
An end in sight in the long search for gravity waves
Our unfolding understanding of the universe is marked by epic searches and we are now on the brink of discovering something that has escaped detection for many years.
Physicists find way to 'see' extra dimensions
Peering backward in time to an instant after the big bang, physicists at the University of Wisconsin-Madison have devised an approach that may help unlock the hidden shapes of alternate dimensions of the universe.
Physicists Seek Answers to Quantum Correlations
First demonstration of a working invisibility cloak
A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working "invisibility cloak." The cloak deflects microwave beams so they flow around a "hidden" object inside ...
Michigan laser beam believed to set record for intensity
If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a ...
Princeton physicists connect string theory with established physics
String theory, simultaneously one of the most promising and controversial ideas in modern physics, may be more capable of helping probe the inner workings of subatomic particles than was previously thought, according to a ...
Scientists present method for entangling macroscopic objects
Was Einstein right? Scientists provide first public peek at Gravity Probe B results
For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct. Saturday, at the American Physical ...
Big Bang's Afterglow Fails an Intergalactic Shadow Test
The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a "Big Bang."
