What If? 22 Crazy Hypothetical Questions (and their Answers)

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…

Simulation of gravitational lensing as a galaxy passes behind a black hole

Black holes are supposedly moving heavy mass eliminating matter. If all matter gets stuck to the horizon, why doesn't all light get stuck on the horizon making a black hole white. Electromagnetic black holes can be observed and tested.Electromagnetic

Black Holes Get Even Weirder with New Stephen Hawking Theory

A computer simulation of what would happen to a gas cloud (the orange-yellow wisp) as it approached a black hole. In short: The cloud would be stretched and squashed like a strand of spaghetti. Credit: ESO/S. Gillessen/MPE/Marc Schartmann

Black Holes Have Simple Feeding Habits

Black Holes Have Simple Feeding Habits At the center of spiral galaxy M81 is a supermassive black hole about 70 million times more massive than our sun.


An artist%u2019s impression of a supermassive black hole at the centre surrounded by matter flowing onto the black hole in what is termed an accretion disk. Also shown is an outflowing jet of energetic particles, believed to be powered by the black hole's spin.


Hawking radiation glimpsed in artificial black hole | Black holes earned their moniker because it seemed nothing escapes – not even light. Then in 1974 Hawking showed that, according to quantum theory, black holes should emit radiation after all... a consequence of the uncertainty principle... Physicists have been toying with laboratory experiments that imitate the physics of an event horizon, where escape from a black hole is impossible because the velocity required exceeds the speed of…


Black holes are some of the strangest and most mysterious objects in the universe. Billions of them may exist in the Milky Way alone. But what, exactly, is a black hole?
