A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

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 ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe – general relativity and quantum mechanics – function perfectly well on their own, 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 ...
