For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the ...

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe ...

Relativistic third-harmonics of a laser in a magnetized plasma channel is studied. Due to relativistic self-focusing in plasma, a high-intensity laser pulse pushes the plasma electrons radially ...

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black ...

Scientists have developed the longest and most complex simulation to date of a binary neutron star collision that results in ...

Could Mysterious Black Hole Burps Rewrite Physics?

A researcher throws cold water on a recent effort that purported to eliminate black holes' greatest and most enduring mystery ...

The monster black hole lurking at the center of galaxy M87 is an absolute beast. It is one of the largest in our vicinity and ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.
