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.

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing group of physicists is treating it as a possible glitch report from the fabric ...

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...

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 ...

Cocoons of debris around dying stars could shake ripples in spacetime unlike any astronomers have ever seen. “This is a potential source of gravitational waves that has never been investigated before, ...

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, ...

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 ...

Gravitational wave signals that seem to emanate from black hole collisions may actually come from the clashes of odd, exotic stars – which have been theorised but may or may not exist. If they do, ...

Supercomputer simulations identify stellar rotation as the mechanism driving chemical mixing in red giants, explaining long-observed surface composition changes during stellar evolution.

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 ...
