For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein's general relativity. One explains the tiny world of particles; the other describes ...

In 1905, a 26-year-old patent clerk named Albert Einstein looked at the universe and discovered that time was not what we thought it was. It was not linear. For centuries, everyone assumed the same ...

Sophia Varughese has two passions: astrophysics and music. Her senior thesis is a scholarly look at black holes and ...

Science says time travel is possible, but probably not in the way you're thinking. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Is time travel ...

The theory of thermodynamic relativity describes velocity (kinematics) and entropy (thermodynamics) under a common physical framework, also leading to an anisotropic adaptation of Einstein’s special ...

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 ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...
