In August 2014 a rocket launched the fifth and sixth satellites of the Galileo global navigation system, the European Union's $11-billion answer to the U.S.'s GPS. But celebration turned to ...

In 2015, the general theory of relativity will be 100 years old. In November 2015, Albert Einstein gave weekly lectures to the Prussian Academy of Sciences in which he set out the fundamental field ...

When the first-ever image of a black hole was released in April 2019, it marked a powerful confirmation of Albert Einstein’s theory of gravity, or general relativity. The theory not only describes the ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...
