From CSIRO: "Eleven year cosmic search leads to black hole rethink"

Commonwealth Scientific and Industrial Research Organisation

One hundred years since [Albert] Einstein proposed gravitational waves as part of his general theory of relativity, an 11-year search performed with CSIRO’s Parkes telescope has shown that an expected background of waves is missing, casting doubt on our understanding of galaxies and black holes. 670 more words
