Using software that incorporates all of the field theory equations developed by Einstein as part of his general theory of relativity, research teams from Europe and the United States have started ...

A UA professor is challenging Albert Einstein’s theory of general relativity and questioning whether it holds up in all areas of space. Andrei Lebed, a physics professor at the UA, has proposed an ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Warp drive has moved a little farther out of science fiction and a little deeper into physics. A new round of theoretical ...
