A newly developed solution to the equations at the heart of Albert Einstein's most revolutionary theory suggests hypothetical stars called "nestars" could be made from stacked gravitational stars, or ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of a wobbly grid representing space-time, in front of a vast field of stars. Theoretical physicists have proposed ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity. But a new study goes one step ahead; it not only links the two theories but ...

New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...

Einstein’s theory of relativity reshaped our understanding of time space and gravity But deep inside its equations lies a mystery the one Einstein never predicted a hole that could change how physics ...

More than a century later, scientists are still proving Albert Einstein right. The famed physicist’s revolutionary general ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. It's difficult to appreciate how revolutionary of a transformation it ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...
