Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

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 ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Physicists have traced three of the four forces of nature — the electromagnetic force and the strong and weak nuclear forces — to their origins in quantum particles. But the fourth fundamental force, ...

Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy. Ever since Albert Einstein’s general theory of relativity recast gravity as curves in ...

Quantum gravity is an attempt to reconcile two theories of physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Quantum gravity is an attempt ...

If the Sun were to spontaneously cease emitting light, we wouldn't know about it for about 8 minutes and 20 seconds. The light that's arriving here on Earth, right at this very moment, was emitted ...
