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

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

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Mind = blown.

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

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 ...

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 ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

Michelson's interference experiment / by H.A. Lorentz -- Electromagnetic phenomena in a system moving with any velocity less than that of light / by H.A. Lorentz -- On the electrodynamics of moving ...
