What happens to light (photons) after they enter a black hole?

Question

Do they pile up into a single point (singularity)? If it continues to move, does its velocity decrease or even increase? Do light particles get destoyed there? If yes, then into what? Or do they behave just as they do in normal situations? How would light 'appear' to 'someone' present inside the black hole (let us assume so), should 'he' happen to be in line with light's motion? Would he be able to feel its presence? Basically, what I actually want to ask is, what goes on inside a black hole -- its thermodynamics, entopy & other properties?

Answer 1

When light enters the black hole, the same thing happens when in the case of light entering into a deep ocean. The black hole like ocean has different levels of layers. When they enter the 1st layer, they refract and their velocity decrease. The further they get into a black hole, their velocity decreases and at a point their velocity is 0. When the velocity is 0, the intensity or contrast of the light is faded and so it gradually vanishes. If some 1 was in the black hole, he would have seen the light provided he is not at (or beyond) the point where the speed(velocity) is 0 and he is not in the line with the ray of light becoz the black hole is so thick, dark and dense that 1 teaspoon weighs 100 billion tonnes and obviously when these situations occurs [not at the point...etc etc], he won't be even able to feel its presence. The density there is estimated 2 b 1,00,00,000 atmospheres or even more. He would b crushed like a waste paper. Some scientists consider it to be an extraordinary "light" absorber which has a presence like a thick black veil in the space....

Answer 2

Obviously one cannot "see" a black hole, but one can see what is happening on its event horizon. This marks the radius inside of which light can no longer escape, but it is not the black hole itself.

We would be able to observe the outside for clues but inside we can only theorize. We can be sure that matter and energy do not behave normally there. Gravity would be so intense that other forces, electromagnetism, the strong and weak atomic forces, would be overwhelmed. Atoms would likely be broken down into individual quarks, flowing and colliding, held together by sheer proximity owing to the pressure of gravity. Photons might maintain their "speed" but would likely not be travelling in a straight line. It would be more like a vibration than a vector.

It's meaningless to describe what an observer inside the black hole observes because an observer is impossible. Matter simply doesn't behave in a way we could "observe". As the mass of a black hole increases, the event horizon might expand but we don't have a clear idea of the limits of things. Some things DO escape from black holes, "geysering" from the poles. How it all balances out will take a lot more study.

Answer 3

Actually, you don't "enter" a black hole, you cross its event horizon. From the point of view of the observer, there's nothing special. In fact, for all we can sense things directly, our entire world is already inside the event horizon of a ginormous BH.

If you were falling towards a large black hole, there is no indication of the crossover point, any more than there is when you cross an equator or a pole. On your trip inwards towards the event horizon, everything behind you speeds up a bit, and light is blue-shifted. By the same token, everything farther in than you appears slow and red-shifted (just as you do to the folks back home watching).

When you cross the event horizon, your observer status changes so far as the rest of us are concerned (but not so far as you are concerned), and we outside simply can't make any pronouncements on any information you do or don't have.

Answer 4

Black hole is the last stage of a star. It has a very strong Field of gravity that it do not allow light to pass trough itself. But on recent pictures of space scientist had found a black hole which is surrounded by stars even with a distance less than 5 km. So we can't say anything perfectly about black hole

Answer 5

I don't think we really have any idea what actually goes on inside a black hole, because we don't have direct observations of what happens inside such an object.

The only way we know that a black hole exists is from radiation around the black hole, as well as the effect it has on nearby bodies. Otherwise we don't know too much about this phenomenon.

Answer 6

Black hole is a concept.... ( Just as we think that there exists Heaven and Hell). The gravitational pull is so high inside that even photon which are very light is pulled in. ( Hence, you see a black hole visually).

The particulate nature of light is when you have it moving. the moment light stops is does not exist. Tell me what happens when sun light falls on your face. it is the same way

Answer 7

no one knows what goes inside a black hole but if you are so curious let me tell you:-
singularity is nothing but the point from which the world, our galaxy,our universe,our mega universe(list can be endless) originated if we something with the speed of light travels through such a huge gravitational object the light changes it`s direction and goes nowhere i.e. singularity but inside a black hole (as you had assumed), if a man can enter his speed will be faster than light (e=mc2 concept) as the mass of the man is greater than the mass of light but no one has gone through black hole, i mean if you travel by the speed of light then also it will take you millions of year`s to reach to the black hole (according to enstin`s concept the you can live for more than hundred years!!! but that is not enough) and if you manage to reach near its magnetic field (you will not notice it as it will be totally dark) you will get sucked inside it and you will end.

Answer 8

They continue to exist until they reach the singularity, then they don't know for sure what happens. Same as everything else in the hole.

Answer 9

It piles up to the singularity. Its all assumptions and based on theories and theoretical analyses.

To find out in real what happens go to a black hole and find out.

Answer 10

No one knows what happens in a black hole
