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 ...

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 ...

Scientists have finally seen the backside of a black hole and in doing so, they've proved that a 1915 theory posited by Albert Einstein was correct. Einstein's 1915 Theory of General Relativity ...

Astronomers have found what is currently the fastest known star in the Milky Way, a faint star racing through the extreme ...

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 ...

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 ...
