In 1919, a total solar eclipse gave the only chance to test Einstein’s groundbreaking General Relativity theory. This video ...

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

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

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

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while ...

Cern researchers are testing traps capable of moving antimatter, which explodes into energy as soon as it comes into contact with regular matter ...

Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be ...

Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.

Researchers at the Indian Institute of Technology Bombay have proposed a new test to measure the “quantumness” of gravity after finding that conventional “quantum entanglement-based” tests may be ...

A new study explains how some supernovae are particularly dazzling—the glow from a magnetic, spinning ball of neutrons called a magnetar. An assist from Einstein is what settled the case ...
