We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles, are the "enfant terrible" of modern physics. Until recently, they were ...

Let the battle begin, Newton Vs Einstein. The all out battle for space-time. Both Albert Einstein and Sir Issac Newton are regarded as the forefathers of physics, but both held different theories that ...

In 1905, Einstein's groundbreaking work showed that the speed of light in a vacuum is independent of the motion of all observers, and the laws of physics are the same for all so-called ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don't seem to work together. Physical phenomena rely on ...
