Mind = blown.

This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

What exactly is … everything? What is space-time? At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...
