An article published in the journal “Science” describes the most precise verification of Albert Einstein’s general theory of relativity outside the Milky Way. A team of researchers led by Thomas Collett of the Institute of Cosmology and Gravitation at the British University of Portsmouth used data collected by the Hubble Space Telescope and ESO’s VLT to observe a gravitational lensing effect, one of the relativistic predictions, created by the galaxy ESO325-G004. The two instruments provided separate data that, compared, confirmed the correctness of the theory.
