The researchers said they spent two years analyzing astronomical data from more than 70,000 galaxies located at distances of up to 3.5 billion light years from Earth. They said they concluded Einstein's theory describing the interplay between gravity, space and time holds true even at vast distances, as it does in more local regions of space.
The scientists, led by Professor James Gunn, said their findings mark the first robust test of the theory at distances that go beyond the solar system.
The study that included Princeton researchers Reinabelle Reyes and Rachel Mandelbaum, Professor Uros Seljak of the University of California-Berkeley, and University of Zurich (Switzerland) researchers Tobias Baldauf, Lucas Lombriser and Robert Smith appears in the March 11 edition of the journal Nature.
