Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...
