Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

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 ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually spectacular simulations ever run on a supercomputer. By folding general ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black hole singularity paradox. By modifying Einstein's theory of general ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...
