Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after ...

The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...

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 ...

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 ...

A star known as S0-2 (the blue and green object in this artist’s rendering) made its closest approach to the supermassive black hole at the center of the Milky Way in 2018. (Nicole Fuller / National ...

Einstein’s theory of general relativity underpins our whole understanding of the large-scale universe. It also has limitations, and researchers have tested it time and time again over the last 100 ...

A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

There are few scientific concepts that are as famous as Albert Einstein's theory of general relativity, but even the iconic theory isn't set in stone. Einstein's theory of general relativity states ...
