This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...
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 ...
The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...
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 ...
In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics ...
