Are black holes?
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole..
What happens if you go into a black hole?
If you jumped into the black hole feet first, the gravitational force on your toes would be much stronger than that pulling on your head. Each bit of your body would also be elongated in a slightly different direction. You would literally end up looking like a piece of spaghetti.
What would you see if you fell into a black hole?
That depends what you mean by “see the future”. It is true that if you watch the outside world as you are falling into a black hole then you will see time evolve faster there. … This is a consequence of general relativity, which explains that the gravity of a massive object causes time to slow down near that object.
What is inside a Blackhole?
A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
Where do things go in a black hole?
It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.
How dangerous are black holes?
Originally Answered: How dangerous are black holes? They are dangerous as much as any other massed body in space outside their event horizon. they are very very very dangerous inside their event horizon.
Will our Sun become a black hole?
Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In about 5 billion years, the Sun will start to run out of hydrogen in its core to fuse, and it will begin to collapse.
Is it dark inside a black hole?
2 Answers. The only light you would see, would be from the stars outside the black hole. Any light that is generated inside the event horizon would be refracted towards the singularity. You wouldn’t see the object in front of you since the light would not reach your eye.
Can a person survive in a black hole?
An observer who remains outside the black hole can’t see through it, but that’s not your problem. As far as you’re concerned there is no horizon. … In fact, in a big enough black hole, you could live out the rest of your life pretty normally before dying at the singularity.
Has anyone been in a Blackhole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.
Is dying in a black hole painful?
If you’re falling into a stellar black hole, you’ll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.
How long does a black hole last?
For example, a black hole of 1 solar mass takes 1067 years to evaporate (much longer than the current age of the Universe), while a black hole of only 1011 kg will evaporate within 3 billion years.
Can a black hole explode?
Eruptions from enormous black holes aren’t uncommon. The explosions are powered by the release of pent-up energy in encircling disks of hot gas. But the team notes that this newfound eruption is thousands of times more powerful than most.
