Unproven Einstein theory of 'gravitational memory' may be real after all, new study hintsEinstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows how this theory of gravitational memory could finally be proven.

'Cosmic Horseshoe' may contain black hole the size of 36 billion suns — one of the largest ever detectedThe "Cosmic Horseshoe" is an Einstein ring, a system made up of a foreground galaxy whose mass is so great, it warps the light from a galaxy behind it. Now, astronomers know where it gets this mass from.
