When neutron stars merge, things get messy

What happens when the densest objects in the universe collide? A neutron star merger is a cosmic forge that creates heavy elements like gold and platinum, but it also unleashes "messy" gravitational waves and gamma-ray bursts that can sterilize nearby solar systems. We look at the violent physics of a kilonova.

Gravitational waves may prove black holes' quantum effect and resolve the dark matter problem

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by LIGO in 2015. These black holes have mass of a few tens of solar mass and, consequently, their Hawking radiation is negligible.

Revealing Gravity Waves

Severe weather — like thunderstorms, tornadoes, and hurricanes — can push air upward into a higher layer of the atmosphere and trigger gravity waves. Aboard the International Space Station (ISS), the Atmospheric Waves Experiment (AWE) instrument captures these waves by looking for variations in the brightness of Earth’s airglow (above). Recently, when Hurricane Helene hit the southeastern United States, AWE caught a series of gravity waves some 55 miles up, pushed by the storm (below). It’s incredible to see these long-ranging ripples spreading far beyond the heart of the storm. (Video credits: NASA Goddard and Utah State University)

“On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA’s Atmospheric Waves Experiment, or AWE, recorded enormous swells in the atmosphere that the hurricane produced roughly 55 miles above the ground. Such information helps us better understand how terrestrial weather can affect space weather, part of the research NASA does to understand how our space environment can disrupt satellites, communication signals, and other technology…”

If Gravitons Exist, this Experiment Might Find Them

There are four fundamental forces in the Universe; strong, weak, electromagnetic and gravity. Quantum theory explains three of the four through the interaction of particles but science has yet to discover a corresponding particle for gravity. Known as the ‘graviton’, the hypothetical gravity particle is thought to constitute gravitational waves but it hasn’t been detected … Continue reading "If Gravitons Exist, this Experiment Might Find Them"

More Evidence for the Gravitational Wave Background of the Universe

The gravitational wave background was first detected in 2016. It was announced following the release of the first data set from the European Pulsar Timing Array. A second set of data has just been released and, joined by the Indian Pulsar Timing Array, both studies confirm the existence of the background. The latest theory seems … Continue reading "More Evidence for the Gravitational Wave Background of the Universe"
