Anonymous users2024-02-07To put it simply, the long river of time began when the universe was great. The concept of time has been there and has meaning since the beginning of the big **, so time is applicable to any place in the universe, and black holes are part of the universe and have their formation process, so there is naturally a concept of time.
As for space, it's hard to say, but there should be a concept of space in a black hole, but we can't imagine it. On our earth, there is a three-dimensional space of length, width and height, and according to Einstein's relative ethics, it is a four-dimensional space composed of three-dimensional space and one-dimensional time. But the universe is mysterious, and there are five dimensions (4 dimensions of space + 1 dimension of time) and six dimensions or even multi-dimensional spaces in the scientific ** universe!
It's just that people who exist in the three-dimensional world can't imagine the appearance of four-dimensional or even multi-dimensional space for the time being, for example, if an ant exists in the two-dimensional space world, he can't see the three-dimensional space of human beings!

Anonymous users2024-02-06Theoretically, yes, in practice there will never be such a situation, even if you run into a black hole, but it seems to us that time goes forward as always, it does not go backwards, it does not disappear, even if the universe is destroyed, time does not disappear, they say that time has a beginning, that is relative, and it has meaning relative to the beginning of time from that point. Check out Stephen Hawking's time brief, it might help you.

Anonymous users2024-02-04Obviously, as you said, time is only a relative concept, a concept that people have agreed to commonly call, just like the latitude and longitude threads, is there really such a thread?

Anonymous users2024-02-02A black hole sucks a person into it and dies.
If your friend sees you fall into a black hole, first your friend will see you turn red, from light to dark, and then you will fade away, and you will be sucked into the black hole.
At first you don't feel uncomfortable, you just feel scared because it's pitch black, you can't see your hands, you feel very heavy, and then you feel weakness and pain in your limbs because your limbs are being pulled by a huge gravitational pull. The limbs are detached and broken because you are torn and stretched by the black hole.
The horror of black holes.
Suppose a black hole is stellar, and as you get closer to the horizon of the black hole, the gravitational pull on you becomes stronger and stronger, and you will fall at an accelerated rate. During this process, the person who falls towards the black hole will not see anything within the event horizon, but the celestial bodies and light above his head will be distorted and constantly spin overhead.
However, the person will not be able to see what he sees when he passes through the horizon, and he will be pulled to pieces when he enters the horizon. Because when the observer is close enough to the event horizon, the tidal effect of the black hole on him is extremely strong.

Anonymous users2024-02-01According to the general theory of relativity, when an object is sucked into a black hole, it experiences a gravitational time delay effect, which means that its time lapse slows down. Specifically, when an object is sucked into a noisy black hole, the speed of time passing slows down to near standstill.
When an object enters a black hole, it is subjected to a gravitational pull so strong that the velocity also disappears. Therefore, no matter what object hits the skin and enters the black hole, its time will slow down. This effect is known as the gravitational time delay effect, and it is very noticeable in phenomena near black holes.
According to the general theory of relativity, when an object is sucked into a black hole, its time lapse slows down, and this also applies to the inside of a black hole. In a black hole, the gravitational pull is infinite, so time also stops. In a black hole, there is no freedom in space, only being pulled by its gravity and moving towards the center of the black hole, but the inside of the black hole is free in the time dimension.
It should be noted that this is only a ** of general relativity, and there are many factors to consider in practice, such as the mass of the black hole, the speed of rotation, the radius of the event horizon, and so on. Therefore, we can't say with complete certainty that the time of entering the black hole will stop.
No, although observations suggest that black holes are a very common phenomenon in the universe, scientists do not yet know exactly what the inside of black holes looks like.
A black hole is a special type of star that forms after the death of a large star. After the nuclear energy of the big star is exhausted, it cannot resist its huge gravitational pull, and can only collapse indefinitely, forming a cosmic singularity with infinite density. The gravitational pull of a black hole is so strong that even light cannot escape from it. >>>More
Will the process of seeing everything around a person in a strong gravitational field become very fast? >>>More
Of course, there is a singularity in a black hole. It is precisely because of the influence of the Schwarzschild singularity that the black hole has a huge gravitational pull that no other celestial body has so far been able to match. As we all know, black holes are arguably the most mysterious and threatening celestial objects discovered in the observable universe so far. >>>More
As far as our sun is concerned, it may become a black hole after death, depending on its mass, a black hole is the final stage of stellar evolution, the star will shrink after its own fuel thermonuclear reaction is exhausted, the massive one may carry out a supernova explosion to reduce its mass to slow down its contraction into a white dwarf star or neutron star, if the mass is superlarge, it will further collapse from the neutron star into a black hole, a black hole is a celestial body with a large mass and ultra-small volume, it is not a "hole" in the literal sense, it is a celestial body, Because its gravitational pull is so great that light cannot escape within its Schwarzschild radius, it appears from a telescope as a "black hole" with a radius of Schwarzschild radius", the black hole will evolve again and eventually become a singularity, which is where the universe was born To add that in fact, black holes are generally not easily observed by telescopes, and it is found that it depends on the trajectory of nearby celestial bodies.
