The evidence for dark matter is everywhere and the evidence for dark matter is nothing. Galaxies rotate in ways that make no sense unless something invisible is adding mass.

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.

The death of a massive, rapidly spinning star can shake the universe. And the resulting ripples—known as gravitational waves—could be felt by instruments on Earth, according to new research published ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the ...

Every few hours, without warning, certain galactic centers light up in soft X-rays and then go dark again — a rhythmic pulse from deep inside a distant galaxy with no obvious trigger. Since the first ...

Rochester Institute of Technology scientists have developed new simulations of black holes with widely varying masses merging that could help power the next generation of gravitational wave detectors.

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

It now takes just a fraction of a minute to detect neutron star mergers, thanks to advancements in a machine-learning-driven approach to astronomy. Reading time 3 minutes A team of researchers just ...

Time variations of (black) zonal and (red) meridional winds along trajectories of LODEWAVE 3. Solid lines represent LODEWAVE data, while dashed lines represent PANSY radar data at an altitude of 18.5 ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward the Big Bang, and the equations run into a singularity, a point where ...

Warp drives are staples of science fiction, and in principle could propel spaceships faster than the speed of light. Unfortunately, there are many problems with constructing them in practice, such as ...
