Satellites glimpse ultra-powerful "black-hole" whirlpools in Atlantic - The whirlpools - never witnessed before - would suck down ships, debris and even living creatures. Satellites have shown two mysterious 'black-hole' whirlpools in the South Atlantic Ocean - ultra-powerful "vortexes" (vortices) which suck water down into the depths
Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world's ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away.
Scientists have discovered the first binary system ever known to consist of a black hole and a ‘spinning’ star – or more accurately, a Be-type star. Although predicted by theory, none had previously been found.
If you were to take a step into a small black hole, your body would most closely resemble toothpaste being extruded out of the tube. Tidal forces are so strong at a black hole's threshold (called the "event horizon") that they would stretch your body into a string of atoms as you fell into the abyss. But if you fell into a somewhat larger black hole with less extreme tides, you could maintain your internal structure. Einstein's theory of time dilation suggests that if you looked forward…
