Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

To construct a warp drive, we'd need 10 times more negative energy than all of the positive energy in the universe. When you purchase through links on our site, we may earn an affiliate commission.

If you believe the Mathematical Universe Hypothesis then yes. And so are you. Quantum phenomena have no subjective qualities and have questionable physicality. They seem to be completely describable ...

"The appearance of such structures sheds new light on the sorts of mathematical objects that nature is built from." Scientists have made the most accurate predictions yet of the elusive space-time ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She calculated that collisions involving three different types of subatomic ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

JONATHAN OPPENHEIM likes the occasional flutter, but the object of his interest is a little more rarefied than horse racing or the one-armed bandit. A quantum physicist at University College London, ...

A common theme in science-fiction media, time travel is captivating. It’s defined by the late philosopher David Lewis in his essay “The Paradoxes of Time Travel” as “[involving] a discrepancy between ...
