Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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. This theory tries to ...

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

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

Most physicists doubt that time exists. On this page 40 years ago, we published scientific ‘proof’ of time being illusory. We pointed out that none of the equations of physics, from Newton’s laws to ...

The fundamental laws of physics insist that no patterns can permanently survive nature’s steady course towards disorder – or can they? A new proof offers a peculiar counterexample to the once-settled ...
