Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

‘I love the idea that this basic principle that Einstein told us about a long time ago is something you can see,’ CU Boulder astrophysicist says Scientists who study the cosmos have a favorite ...

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

Gravity causes galaxies to rotate. Astronomers can study the speed of stars at different distances from the galactic center to look for evidence for dark matter or other new physics. The majority 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 ...
