A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged.

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire ...

Astronomers have identified the closest ever Einstein ring, a rare phenomenon where light from a further-off galaxy is bent by the gravity of a galaxy closer to Earth. The ring was previously ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges.

Albert Einstein, in 1905, presented the revolutionary idea of light quanta of energy which equals ħw, where ħ is reduced Planck's constant.

Einstein's theory of general relativity predicts gravitational memory, where space-time retains imprints from passing gravitational waves. Researchers are exploring if the cosmic microwave ...
