Below we have 10 mind-blowing facts about black holes -









1) You can’t dir ectly see a black hole -

Because of it's immense gravitational force- no light can escape from it . It is impossible for us to feel the hole directly through our instruments, regardless of the type of electromagnetic radiation you use (light, X-rays, whatever.) The key is to look at the effects of the black hole on the neighbouring environment, stresses NASA. Let's say a star is too close to the black hole, for example. The black hole shoots naturally on the star and rips it into shreds. When the matter of the star begins to move towards the black hole, it becomes faster, gets hotter and glows brightly in the X-rays.





2) Look out! Our Milky Way has a black hole -

A subsequent natural question is given how dangerous a black hole is, is the Earth in imminent danger of being swallowed? The answer is no, astronomers say, although there is probably a huge supermassive black hole lurking in the middle of our galaxy. Fortunately, we are far from this monster, we are about two thirds of the way out of the center, compared to the rest of our galaxy, but we can certainly observe its effects from afar. For example: the European Space Agency says it is 4 million times more massive than our sun, and is surrounded by surprisingly hot gas.





3) Dying stars create black holes-

Let's say you have a star that is about 20 times more massive than the sun. Our sun will put an end to its life quietly; When its nuclear fuel burns, it will slowly fade into a white dwarf. This is not the case for much more massive stars. When these monsters run out of fuel, gravity will overwhelm the natural pressure of the star maintains to keep its shape stable. When the pressure of nuclear reactions collapses, Gravity submerges violently and collapses the nucleus and other layers are thrown into space. It's called a supernova. The remaining nucleus collapses into a singularity - a spot with infinite density and almost no volume. It is another name for a black hole.





4) Black holes come in a range of sizes-

There are at least three types of black holes, says Nasa, ranging from squeaks relative to those dominating a center of the galaxy. The primal black holes are the smallest, and range from the size of an atom to the mass of a mountain. Stellar black holes, the most common type, are up to 20 times more massive than our own sun and are probably sprinkled in the dozens in the Milky Way. And then there are the gigantic in the centers of galaxies, called "supermassive black holes". They are each more than 1 million times more massive than the sun. How these monsters formed is still being examined.





5)Weird time stuff happens around black holes.

This is best illustrated by one person (call him A) falling into a black hole while another person (call them B) watches. From B’s perspective, A's clock appears to be ticking slower and slower . This is in accordance with Einstein’s theory of general relativity, which (in short) says that time is affected by how fast we go, when you’re at extreme speeds close to light. The black hole warps time and space so much that A’s time appears to be running slower. From B’s perspective, however, his clock is running normally and Lucky’s is running fast.
