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 ...

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 ...

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 ...

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 ...

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.

HOUSTON—Blue Origin’s 29th New Shepard suborbital launch on Feb. 4 successfully provided 30 technology payloads with brief exposure to simulated lunar gravity conditions, a first for the company’s ...
