Einstein’s strangest optical illusion has been captured—thanks to lasers, a cube, and a bit of artistic inspiration.

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

A bold new quantum theory of gravity may finally bridge the long-standing rift between Einstein’s general relativity and quantum field theory. This potential "Theory of Everything" could answer some o ...

A Growing Mystery The discovery of the Universe’s accelerating expansion in 1998 left scientists scratching their heads, ...

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

A prediction of the gravitational waves produced by interacting black holes achieves high precision and demonstrates the link between general relativity ... must use Einstein’s equations to ...

You scrambled up a Rubik's cube, and now you want to put it back in order. What sequence of moves should you make?

A long-elusive "theory of everything" may finally be within reach as Finnish researchers unveil a new quantum theory of ...

Einstein spent the next 10 years trying to include acceleration into the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion ...
