Albert Einstein’s name has become shorthand for genius in theoretical physics. We tend to picture him scribbling equations ...

When two massive black holes slammed into each other earlier this year, astronomers were able to observe it in the clearest ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions ...

Einstein's equations have held up remarkably well for over a century. But they leave tantalizing gaps in our knowledge. A spectrogram shows the rising frequency of gravitational waves emitted by a ...

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 ...

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 ...

Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation of how the universe ticks. But there are some holes ...

More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in ...

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 ...

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 ...

While Einstein’s theories and work continue to shape reality as we know it, one anonymous enthusiast was recently able to walk away with a bit of the famous physicist in the form of pages of notes ...

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 ...
