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 ...

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 ...

Albert Einstein’s general theory of relativity predicts that a rotating mass like the Earth pulls the fabric of space and ...

The interior of black holes remains a conundrum for science. In 1916, German physicist Karl Schwarzschild outlined a solution to Albert Einstein's equations of general relativity, in which the center ...

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

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 ...

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 ...

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 ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...
