What is black hole and how it is formed?
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.
What causes black holes to occur?
Some black holes form when a massive star collapses into itself. The most well-understood black holes are created when a massive star reaches the end of its life and implodes, collapsing in on itself. A black hole takes up zero space, but does have mass — originally, most of the mass that used to be a star.
Will Earth end up in a black hole?
There are no black holes close enough to Earth to affect us. If Earth gets within about 800,000 kilometres (3.7 light seconds) of this black hole it will get pulled apart. But that’s unlikely to happen and certainly not in your lifetime. V616 Monocerotis is about 3,300 light years away.৩০ জুলাই, ২০১৯
Is black hole a reality?
We have grown accustomed to the idea of black holes, but their existence took time to gain acceptance. Added to recent detections of gravitational waves from black hole mergers, the reality of black holes has become inescapable. The theory that an object might be dense enough to trap light is more than 200 years old.৬ অক্টোবর, ২০২০
What’s on the other side of a black hole?
The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.২৭ জানু, ২০১৪
Where is the nearest black hole?
Sagittarius A
Can you see a black hole with your eyes?
You can’t see them with the naked eye No matter how hard you stare, you won’t be able to spot a black hole all on your own! The reason black holes are so black is because they consume everything around them, including light! That’s what astronomers can use to identify a hole.
Why can’t we take a picture of a black hole?
So black holes aren’t the only things that can bend light beams, but they do elevate the art; instead of light being slightly deflected, it can completely change direction or even literally go into orbit.১৪ এপ্রিল, ২০১৯
Can things come out of a black hole?
The things that fall in through a black hole’s event horizon don’t come out again, not under any circumstances. There may be plenty of light that arises from black holes, but none of it can ever come from inside the event horizon.২১ ডিসেম্বর, ২০১৯
What happens to your body if you die in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.২৭ জুলাই, ২০১৪
