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 ...

Physical equations enable us to predict the future, but singularities imply a lack of predictability; theory just breaks down ...

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 ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the ...

B lack holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a t ...

This "latent" mass exceeds the observable mass of the universe by a factor of 40. We also show that in general relativity, GR, there are no fundamental laws of conservation of energy -momentum and ...
