Black holes are some of the most mysterious objects in the universe, but they aren't always silent. When two black holes are close enough to each other, they spiral toward one another, eventually ...

Researchers discover rotating spiral brain waves that travel across cortical networks, acting as a space-and-time clock for ...

Astronomers have revisited data from a dramatic collision of neutron stars to help resolve the infamous ‘Hubble tension’.

Scientists studied ripples in space-time, called gravitational waves, after two black holes collided. Read more at ...

The interaction of light with objects and media moving at relativistic and superluminal speeds enables unconventional phenomena such as Fresnel drag, Hawking radiation, and light amplification.

Metasurfaces have attracted increasing attention due to their powerful capabilities in manipulating electromagnetic (EM) waves. However, most of the existing designs are restricted to independent ...

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

Asymmetric collapse: Simulations of core-collapse supernovae indicate that existing gravitational-wave detectors such as LIGO could spot telltale signs of cosmic distortions known as gravitational ...
