There is no denying the awesome predictive power of Albert Einstein's 1915 theory of gravity, general relativity — yet, the ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a ...

Sheldon Glashow has strong opinions about string theory. Like how it has failed in its primary goal of incorporating gravity into the standard model of elementary particles. How its inability to ...

Early NASA concept for creating artificial gravity. Of course, there’s an obvious problem with this: every hour spent exercising in space is an hour that could be better spent doing research or ...

It is currently thought that understanding the quantum gravity is a last major frontier of physics where one aims to build a consistent theory involving two great new theories of the 20th century ...
