Thomas Edison’s 146-question employment test was so difficult that the inventor’s own son—as well as Albert ...

Einstein rings of light are produced when two galaxies are almost perfectly aligned, with one behind the other from a fixed perspective. They are one of the best examples we have of gravitational ...

"For me, with a lifelong interest in gravitational lensing, that was amazing." Named after Albert Einstein, one of the greatest scientists to have ever lived, his theory of relativity states that ...

Professor Thomas Collett, from the University of Portsmouth’s Institute of Cosmology and Gravitation, said such rings can help scientists test Albert Einstein’s general theory of relativity. He said: ...

Gravity distorted the light from this more distant galaxy, thus the name honoring Albert Einstein. The process is known as gravitational lensing. This photo provided by the European Space Agency ...
