We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether ...

k{g^{- 2}}\). Overall this equation is simpler than it looks as long as you ensure that: distance is given between centres units are all in metres and kilograms The force of gravity exists between ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.

His simple equation for universal gravitation, written in 1666 when he was 23, helped overthrow more than a thousand years of Aristotelian thinking (reinforced by Greek astronomer Claudius Ptolemy ...
