For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Astronomers have identified the birth of a magnetar, a hyper-magnetized neutron star, by detecting a subtle warping of space-time predicted by Einstein’s general relativity. The discovery came from ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the ...

It was 1905, and Albert Einstein had just turned theoretical physics on its head by publishing a paper on what later became known as special relativity. This showed that space and time could not be ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Astronomers have detected strange "wobbles" in the light curve of a super bright supernova, hinting that a magnetar was born ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...
