Trying to solve quantum gravity is frustrating. We have made tremendous progress in quantum theory, but it seems that every ...

Yet it is not regarded as absurd today. After exhaustive proofs of entanglement's authenticity in the real world, it is now the key resource in quantum information theory, allowing quantum ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

A time crystal more complex than any made before has been created in a quantum computer. Exploring the properties of this unusual quantum setup strengthens the case for quantum computers as machines ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...
