BLACK-HOLES were theorized by Albert Einstein in 1915. Term blackhole was COINED by J.A. Wheeler in 1960. A black hole is a place in space where gravity pulls so much that even light can not escape. The gravity is so strong because the MATTER has been squeezed into a tiny space.This can happen when a star is dying. Scientists think the smallest black holes formed when the universe began.Stellar black holes are MADE when the center of a very big star falls in upon itself, or collapse.Scientist at Event Horizon Telescope Project have released the first-ever image of Black Hole.The black hole is located in the center of Galaxy Messeir 87, in the constellation Virgo.
