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: ...

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

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

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 ...

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 ...

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

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst ...
