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

NASA supercomputer simulations reveal X-ray and gamma-ray signals emitted in the final milliseconds before neutron star mergers, providing insights for future observatories and gravitational-wave ...

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 ...

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, ...

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 ...

New models explain how small black holes in the early universe beat the clock and grew into massive objects within millions ...

Astronomers have created the first model for how debris around exploding stars could emit gravitational waves powerful enough to be detected by instruments on Earth. When you purchase through links on ...

We are all bobbing in a sea of ripples in space-time, called gravitational waves, reverberating through the fabric of the universe, scientists announced on Wednesday. Those ripples are probably the ...

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 ...
