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