The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

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 ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn't just expanding, but the expansion rate that we infer for distant galaxies is accelerating: their recession ...

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, ...
