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

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

A new experiment will test the notion that gravity, one of the fundamental forces in the physical world, relies upon quantum physics to work. If so, it would further indicate the centrality of quantum ...

Early on in science classes all over the world, students drop diverse things to learn how gravity works and how outside forces might affect the rate of fall. But the science of falling goes well ...

Gravity, despite its pervasive influence, is the weakest fundamental force, easily overcome even by simple actions like lifting a pencil. While achieving and maintaining orbit requires significant ...

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 ...

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale. A group of researchers at the University of Waterloo and the ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

When Albert Einstein introduced his theory of general relativity in 1915, it changed the way we viewed the universe. His ...
