Link to Throuh the wormhole: 2- The riddle of blackholes documentary
Documentary Description
They are the most powerful objects in the universe. Nothing, not even
light, can escape the gravitational pull of a black hole. Astronomers
now believe there are billions of them out in the cosmos, swallowing up
planets, even entire stars in violent feeding frenzies. New theoretical
research into the twisted reality of black holes suggests that
three-dimensional space could be an illusion. That reality actually
takes place on a two-dimensional hologram at the edge of the universe.
