New research has uncovered an unexpected flaw in Einstein’s theory of relativity — a gap that no one had the tools to detect ...

A single sewing needle is tiny enough to slip through fabric unnoticed, yet physics suggests that if it somehow struck Earth at light speed, the result would look less like a pinprick and more like a ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

ABSTRACT: In this paper, we explore a theoretical framework aimed at bridging general relativity and quantum mechanics by employing the Feynman path integral formalism. Starting from Einstein’s field ...

The special theory of relativity arose as a way of accounting for the facts of electromagnetism. We have here a somewhat curious history. In the eighteenth and early nineteenth centuries the theory of ...

For the first time, physicists have demonstrated a phenomenon known as the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp before our eyes. The new findings, ...
