Physicists who disproved ‘5th force’ win $3 million ‘Breakthrough’ prize

Posted by in categories: cosmology, physics

Three physicists won a $3 million Breakthrough prize for proving there is no fifth force (that we know of). And it all started with a series of table-top experiments using cheap equipment.

Eric Adelberger, Jens Gundlach and Blayne Heckel together lead the “Eöt-Wash Group,” which is devoted to precise tests of physical laws. They take their name from the early-1900s physicist Loránd Eötvös and the University of Washington, where they work. These Eöt-Wash researchers got their start in the mid-1980s, using a device known as a “torsion balance” to disprove claims of an undiscovered fifth force in physics. Since then, they’ve used more elaborate versions of the same device to test the true strength of gravity, detect the tug of dark matter in the Milky Way and search for theoretical physical effects like extra dimensions and “axion wind.”

Researchers Find the Origin and Maximum Mass of Massive Black Holes Observed by Gravitational Wave Detectors

Posted by in categories: cosmology, physics

Through simulations of a dying star, a team of theoretical physics researchers have found the evolutionary origin and the maximum mass of black holes which are discovered by the detection of gravitational waves as shown in Figure 1.

The exciting detection of gravitational waves with LIGO (laser interferometer gravitational-wave observatory) and VIRGO (Virgo interferometric gravitational-wave antenna) have shown the presence of merging black holes in close binary systems.

Monumental Collision of “Impossible” Black Holes Detected for the First Time

Posted by in categories: cosmology, physics

The most massive black hole collision ever detected has been directly observed by the LIGO and VIRGO Scientific Collaboration, which includes scientists from The Australian National University (ANU).

The short gravitational wave signal, GW190521, captured by the LIGO and Virgo gravitational wave observatories in the United States and Europe on May 21 last year, came from two highly spinning, mammoth black holes weighing in at a massive 85 times and 66 times the mass of the Sun, respectively.

But that is not the only reason this system is very special. The larger of the two black holes is considered “impossible.” Astronomers predict that stars between 65 – 130 times the mass of the Sun undergo a process called pair instability, resulting in the star being blown apart, leaving nothing behind.

Unexpected Electrical Current Discovered That Could Stabilize Fusion Reactions – Bringing the Fusion Energy That Drives the Sun to Earth

Posted by in categories: nuclear energy, physics, space

Electric current is everywhere, from powering homes to controlling the plasma that fuels fusion reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before. The novel findings could give researchers greater ability to bring the fusion energy that drives the sun and stars to Earth.

“It’s very important to understand which processes produce electrical currents in plasma and which phenomena could interfere with them,” said Ian Ochs, graduate student in Princeton Universitys Program in Plasma Physics and lead author of a paper selected as a featured article in Physics of Plasmas. “They are the primary tool we use to control plasma in magnetic fusion research.”
