For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

The theory of general relativity upended the world of physics and even its author resisted accepting a bizarre phenomenon the ...

Einstein's fascination with light, considered quirky at the time, would lead him down the path to a brand new theory of physics. Living half a century before Einstein, a Scotsman, James Clerk Maxwell, ...

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 ...

Although Einstein’s Theory of Relativity is typically associated with really large and really heavy things like planets in ...

For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum mechanics, which govern the smallest particles, fit with the laws of ...

A peer-reviewed paper published in The European Physical Journal C presents a modification to Einstein’s general relativity that eliminates the singularities associated with the Big Bang and Big ...

For years, astronomers have wondered why real-life versions of Tatooine are so rare. With thousands of confirmed exoplanets and countless binary star systems in our galaxy, planets orbiting two suns ...
