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.

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 ...

A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

Rosie is a freelance writer living in London. She has covered everything from ancient Egyptian temples to exciting medical breakthroughs, but she particularly enjoys writing about wildlife, ...

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 ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

Space-based gravitational wave detection hinges on the precise free-fall of test masses within an interferometric framework. These free-falling cubes, typically composed of gold‐platinum alloys, are ...

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...

When two sufficiently massive objects collide — such as when two black holes merge — the forces can actually bend space-time, creating ripples called gravitational waves. These gravitational waves can ...

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 ...

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 ...
