Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Solar eclipses are a rare and brief opportunity for scientists to gather data on everything from the physics of the sun to ...

Albert Einstein’s general theory of relativity predicts that a rotating mass like the Earth pulls the fabric of space and ...

More than a century later, scientists are still proving Albert Einstein right. The famed physicist’s revolutionary general ...

In the early 1900s, Albert Einstein proposed the theory of general relativity, which challenged everything scientists believed they understood about the universe at the time. Over the years, ...

An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of ...

Use left and right arrow keys to seek audio. Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this ...

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 ...

One day, a mind-bending device called the gravity telescope might bring us visceral pictures of exoplanets far beyond our solar system. Monisha Ravisetti was a science writer at CNET. She covered ...

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 ...
