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 ...

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 ...

Scientists from Vilnius University (VU) Faculty of Physics, along with members from Poland and other countries, discovered a rare planet using a space-time phenomenon first predicted by Albert ...

A trippy fringe theory suggests that time is the source of all physical matter, and space is merely a byproduct. According to Gunther Kletetschka, a geologist from the University of Alaska Fairbanks, ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

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 ...
