A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

HERE is a readable book, excellently translated, for which we have again to thank Mr. H. L. Brose. Though it is called an introduction to the theory of relativity and gravitation, it is more strictly ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

Teaching relativity to a dog may sound like a hopeless mental exercise, but physics professor Chad Orzel says it actually makes the job of teaching relativity to humans easier. "It makes the whole ...

Susskind and Friedman follow their collaboration on Quantum Mechanics by probing the mathematical nitty-gritty of field theory and Einstein’s theory of special relativity in the third installment of ...

Strangely, although we feel as if we sweep through time on the knife-edge between the fixed past and the open future, that edge—the present—appears nowhere in the existing laws of physics. In Albert ...
