The first test of strong gravity was the Laser Interferometer Gravitational-Wave Observatory's (LIGO) observation of gravitational radiation from two colliding and merging black holes. Moreover, the centre of the black hole has time and space curved up to the extent that law of physics break down. This computer corresponds to an image, as it would have been taken from a giant telescope with the diameter of the entire telescope network - the Event Horizon Telescope. This black hole is seven billion times the mass of the sun. The observatories, located in Hawaii, Arizona, Chile, Mexico, Spain and Antarctica, individually captured the black hole's radio signals over four nights in April 2017, when the weather was optimal in all six regions. Black holes are thought to be the "driving engines" of galaxies, "affecting the largest scales of the universe", she added.
"Here it is", Sheperd Doeleman, a Harvard astronomer and project director of the EHT, said as he revealed the image at the Washington briefing. "The black hole is the Dark Souls dark sign", @GenePark tweeted, referencing the notoriously hard video game. Allow us to explain; a black hole that has a mass of 4.1 million suns will only be about 15 million miles wide.
An worldwide consortium of scientists is expected to release the first ever photos of a black hole. But at a distance of 55 million light-years away, it is only about 42 microarcseconds big (~0.0000000116th of a degree), which for context is how big an orange on the moon would appear to someone on Earth.
Black holes are invisible, but scientists know they are present because of the effect they have on other things in a galaxy. M87's black hole seems to have a far brighter crescent-like shape on the bottom left.
The existence of black holes, first proposed by Albert Einstein in his 1916 general theory of relativity, has been known for decades. And it is one of the heaviest black holes that we think exist.
