Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase in ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Gravity is everywhere. It’s the force that anchors the Earth in ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...
