HELSINKI — Chinese commercial launch firm Orienspace is aiming for a late 2025 debut of its Gravity-2 rocket following a recent first-stage engine hot fire test. Orienspace announced July 8 that it ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

There are some things in life that just sort of happen. Desks get covered in dust and scraps of paper. Clothes get dirty and the laundry basket fills up. Weeds slowly creep across an untended ...

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 ...

The idea is still new and requires a lot of assumptions in its calculations to make it work. Over the years, experimental results have been mixed. When you purchase through links on our site, we may ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?
