A black hole was a region of spacetime featuring a gravitational field so strong that not even light could escape.[1] They were the product of extremely massive stars collapsing into points dense enough to warp the fabric of spacetime.[1]
Stephen Hawking wrote about black holes in his book A Brief History of Time.[2]
