The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.

What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

Thomas Mulligan explains how the orbit of star S2 near a black hole provides proof for Einstein’s theory of relativity.

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

The Big Bang Theory, combined with Einstein’s theory of general relativity, has explained many of the universe’s biggest questions — from the cosmic microwave background to its large-scale structure ...

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

DUT Quantum Simulator interface: a decentralized scientific tool for testing cosmological hypotheses based on non-singular ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe. If true, it could explain the nature of dark matter and much more ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what ...

Albert Einstein 's theory of general relativity —which explains gravity as the product of the distortion of space and time—may not be universally applicable.
