Less than half a second after the first direct evidence of gravitational waves was recorded on 14 September 2015, a very short, faint signal was registered by NASA’s Fermi Telescope from the same region in space.
High-energy light particles called gamma rays were caught emanating from a black hole merger in the area, and the discovery will not only help physicists pinpoint the exact source of the gravitational wave – if confirmed, it has huge implications for our understanding of the fundamental physics that govern our Universe.
“This event – which in itself is a big deal, seeing as no one had ever spotted a binary black hole merger before – was so massive that it significantly warped the fabric of space time, creating ripples that spread out across the Universe… finally reaching us last year.”
