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

The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the supernova known as SN 2024afav settled into something stranger. Its brightness ...

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 ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

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 ...

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

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...
