5 shocking facts that you did not know about black holes

Recently, Stephen Hawking, the genius of modern physics, declared: perhaps black holes - the door in an alternate universe. It turns out, they do not matter disappears and travels to another world! Black holes are still poorly understood, but thanks to Einstein's relativity theory, scientists were able to predict and calculate their appearance, size and other physical properties. The most interesting that the latest space research confirm these calculations. Website chose the most interesting facts about black holes.





1. A black hole consists of "nothing" It is known that a black hole is formed after some star fully use up their nuclear fuel (which it maintains its enormous temperature of up to 100, 000 ° C) and "collapses". This is the "collapse" captures the time and space, distorting them, inside a black hole is not a matter only twisted - like a crumpled piece of paper - time and space. To better understand this, imagine an ant that lives on a trampoline if on a trampoline put a stone, it will sag, but the ant is too small to see. But with the help of physics it can measure the trampoline - his universe - and guess what it is curved. Time is simply bent under the laws that led Einstein. And the very same star swallow hole.

2. Near the black hole stareyutPredpolozhim people do not, there is a way to bring a man to the black hole and make sure that the ship is not sucked in. Being near the black hole, the astronauts grow old only for a few hours, and the world will take years. And all because the time near a black hole is flowing very slowly, barely moving.

3. A black hole can destroy the solar sistemuV the vicinity of the solar system there is no black hole. Otherwise, this has led to the impression nightmare! Near the black hole is a very strong gravity, which necessarily would affect Earth's orbit. Our planet, or much nearer to the Sun, which used it all burned alive, or flew away from the universal source of heat and cold. And it can, and left the solar system, or become a prisoner of the black hole. Scripts are many, but one thing is clear: during the year (though, most likely, a couple of months) of mankind would be killed.

4. The black hole can disperse objects to speed svetaEsli you suddenly want to fly to another galaxy at nearly the speed, will help double black hole - a pair of black holes orbiting each other. One need only turn to spin in orbit of these black holes - like a circus performer goes on a bicycle in a circle, balancing to keep his balance. Flight from one hole to another, the ship will be gaining more speed. And when it becomes almost the speed of light, it will just go circling orbit and go to its target - the planet or star in a neighboring galaxy.

5. Why is a black hole is called "black" Although the black hole does not contain matter, it has a surface - the "event horizon." It's kind of stopper, through which nothing can leak out - no radio, not even a particle of light, moving at overspeed. Hence the word "black" in the title. However, Hawking's recent statement that the substance does not sink into the hole, but remains at the event horizon, casts doubt on the idea that black holes can not be selected.
