Touching Black Hole?

Question

For time being, lets consider that the laws of Physics dont imply on us, and hence lets assume that the balck hole is absolutely infective on us. Now if we reach towards the black hole, get inside its horizon and try to touch it physically, then how will it feel? Will it be something solid? What will be its temperature? Further, lets assume that we have landed on the black hole's surface, and now would like to see its colour with a super vision capability - What could be its color - any other possibilities apart from black?

Answer 1

Suspending the effects on us and our spacecraft for arguments sake, and assuming black holes have a surface rather than a point singularity inside the event horizon, I think the following would be true:

1.) The surface would feel like a perfect fluid with zero viscosity. The recent experiments as the RHIC (Relativistic Heavy Ion Collider) have created what evidence points to being miniature black holes and that they had the properties of a perfect fluid.

2.) Again, science speculates that the surface temperature of a black hole would be as close to absolute zero as possible. Reason being, to my understanding, that with such large gravitational forces, even heat cannot escape because heat transfer happens via convection (slower than light), conduction (slower than light) or radiation (same as light) - thus if light can't get out, neither can heat. Also, heat is a measure of average kinetic energy of the particles in a system. With gravity like that, how is a particle supposed to wiggle in the first place?

However, as you move from the event horizon toward the singularity, the space between the two gets progressively hotter as the in falling matter and energy is squeezed.

3.) I think the color would be black - again, the escape velocity for light is higher than light can travel so it wouldn't be able to escape and reach your eye. The complete absence of light is as dark as dark can get. Looking up would be interesting though - you would see the stars and other stuff, but you would have all sorts of distortions and ghost images from the gravitational lensing. The image would probably look like a tunnel that narrows to a point at the actual surface.

Come on people - its a thought experiment. The asker specifically wanted us to suspend the effects of physics on the hypothetical observer for the sake of discussion.

Answer 2

Good that you're curious about black holes, so that you want to understand what it's like to be in the vicinity and "inside" the Schwarzchild radius of the black hole. It's not silly to inquire about the "conditions" in such extreme places, even though your physical body will already be long shredded into atoms before you even got close to the event horizon, which is the Schwarzchild radius, of a real black hole. The event horizon is not a physical boundary, but simply a "point of no return", marking the radius where even light cannot escape from it. Things will fall "through the event horizon" unimpeded. Because light rays are so warped in the vicinity, the visual appearances will be bizarre. If you are spiralling towards the event horizon, it will look like the black hole is an infinite, flat wall, while all the stars of the universe will be visible on the other side. Because the black hole is very likely to be spinning, matter and processes in the vicinity of the black hole will have a complex structure, composed of a spinning disk feeding matter into the black hole, only to have much of it ejected straight outwards from the poles of the spinning black hole in vast plumes. Every color of the electromagnetic spectrum can be expected in this wild and extremely furious show, and temperatures can be expected to be in the billions of degrees. This is all before you even pass through the event horizon! Once you enter, then you've truly passed through the Looking Glass, and the very dimensions of time and space will seem to have reversed roles, where time has become space with static locations, and space has become time which flows, so that as one hurtles towards the final singularity, it would be like waiting for the end of the universe.

Answer 3

OK, I'll explain why others refuse to answer your question;:
1. If the law of physics doesn't imply on us, we wouldn't feel or see anything from the black hole, since heat transfer or light propagation doesn't work for use (i.e. we wouldn't feel anything)
2. If you don't understand the above statement, I'll need to change your question into: "What if we become an imaginary metaparticle, something that cannot be touched, cannot be destroyed, is capable of moving through the space freely, unaffected by gravities, but it can feel heat difference, capable of recording motion, and interpreting them, capable of feeling the solidness of something. And we go to the black hole?"

I think it would be extremely cold at the horizon, and extremely hot in the black hole's core. And the black hole's horizon would be neither solid nor liquid. What we'll see in the horizon is pure true black (no electromagnetic wave at all), but when we're standing in the core, it'll be a mixture of every electromagnetic wave at all frequency bands at a very high magnitude.

Answer 4

That is a very interesting question actually. Since the laws of physics do not apply after you fall through the black hole's event horizon, I will use my imagination and my little science background.

There are no possibilities other than black; there is nothing escaping a black hole, not light or other electromagnetic radiation; in order for infrared goggles to work or other such equipment there must be something released from the black hole. Black holes suck material in them.

As for how it would feel, I have absolutely no idea. I do not even know that much about black holes to be able to speculate correctly.

Answer 5

If 2 black holes are attracted to a minimum of one yet another they're going to the two get into direct collision, they're going to spiraling inward till they finally merge. The merger, in spite of everything, particularly of coming mutually appropriate, would be with forces so intense that one black holes is kicked away, particularly of imploding, at an incredible velocity, by no skill to return.The incident would inject gasoline and airborne dirt and dirt into its surrounding which will blaze with a comfortable X-ray flare that would final hundreds of years. A computer virus hollow has by no skill been stumbled on, not even interior the colliding black hollow. Mergers between black holes are uncommon events, yet whilst it does take place, the afterglow will lasts long sufficient for us to have the skill to discover them conveniently. The researchers estimate that there must be as many as one hundred of those events happening interior 5 billion easy-years of the Earth.

Answer 6

how would it feel if it would be possible to touch? it would be hot, from all the compression that is going on. remember, once you enter the horizon, you can't leave it. people nearby would not see past the horizon, it will look like your hand is sitting still on top of the horizon, because light stops there.

the surface? the color is not black. the reason they are called black holes are because they are not seen in the blackness of space. also, if you were inside, you could not see anyway. light will not be able to bounce off anything and then travel to your eyes. light will be sucked to the center of the hole, as well.

Answer 7

I agree with Paulie...this is really just a dumb question (with all due respect). You can't ignore the laws of physics when describing what you would experinece in touching a black hole. For all the "exceptions" you state, I could say that it looks and feels like warm soft black velvet. Prove me wrong.

Your question has no answer.

Answer 8

while entering Event horizon you will not make any difference only the person standing out side the event horizon will notice that you are doing all things slower & slower & for out side person it will look every thing redder. after you enter the event horizon out side person will not be able to see you

For person who has entered event horizon as long as he does not hit singularity he will feel everthing as normal as rest of unverse ( provideed you have extra ordianary power to bear gravity & temperture) & smaller black holes have higher temperture & vice verse so temperture dependes on size of the black hole

when you hit singularity of black hole you will become part of it. From singularity no matter has any escape, nither your senses have

So with all your supernatural power fly around singularity but never touch it. in case if you come out black hole you will come out in some other part of universe & some time in the past

Answer 9

Uh....

I'm not sure you can consider the phyiscs of something without considering the physics of something.

Black Hole Thermodynamics are pretty complicated, a pretty difficult and controversial topic in physics. I don't think there are any easy answers.

Answer 10

How can anyone say you are stupid for asking this question when no-1 knows what exists there.Who even knows that our theories apply to anything out there, i assume we try to make them apply.I think its funny when people who understand physics and astronomy seem to feel so confident in what they say.Lets be honest its mind boggling and the opinion of the housewife in berkshire whos washing her pots is probrably as gd as stephen hawkings when it comes to black holes and the universe.
