In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Professor Lawrence Krauss, department head of physics at Case Western Reserve University, will give a talk at the University of Massachusetts tomorrow. The lecture is called “Einstein’s Biggest ...

Yeah, yeah, Albert Einstein. Smart guy. This being summer, you see his face on T-shirts, sticking out his tongue, as if to say, “Ask the guy wearing this if he can explain fractions.” Props to ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

In a 1923 book called “The Principle of Relativity,” Albert Einstein seemed to call out to better-equipped scientists of the future to establish the truth of his mind-bending theoretical work. “Apart ...

The research that leads to a Nobel Prize in physics can sometimes be a little obscure. In 1990, for example, three scientists got the nod “for their pioneering investigations concerning deep inelastic ...
