Gravity may not be a fundamental force of nature, but a byproduct of the universe streamlining information like a cosmic computer. Reading time 3 minutes We have long taken it for granted that gravity ...

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, fluid motion and observed data, hundreds of these models agree that more carbon ...

Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists ...

As Earthlings, most of us don’t spend a lot of extra time thinking about the gravity on our home planet. Instead, we go about our days only occasionally dropping things or tripping over furniture but ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose discovery will finally ...

Gravitons, the particle of quantum gravity, may be impossible to detect. To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity.

Rather than viewing gravity as the source of pathologies, the researchers treat it as the medicine. Their positivity-bound analysis argues that, within the assumptions of their EFT and bounds, the way ...

A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself, but with ...
