For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

1 / 6 | Each exact solution of the mathematical relations of general relativity (Q1) has a name. Name this person, who solved the relations for what space looks like around a spherical and ...

Mind = blown.

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 ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...
