I found very interesting that if the black hole is not rotating, the object will be pulled directly to the center of the black hole (the singularity), where the object is “squeezed out of existence or zero volume". So then does this mean that the object stretches vertically because it’s pulled toward the singularity, but if there’s no force acting horizontally then, the object will become longer like a worm. Well, if the object gets longer and longer (extremely thin) as it gets closer to the singularity, doesn’t it disintegrate because of the extreme force on it? And what exactly happens at the singularity?
On the contrary rotating black holes are just impressive. Because the singularity in this kind of black hole is shaped like a ring, if you would pass through the center of the ring without touching it, then it’s possible you could emerge into another time and another place in this universe or into another universe (sounds like science fiction?). Anyways, what would be the probabilities to pass through the center without touching the ring? And how big is the ring??

so the black hole can be connected to the "other worlds" theory...because the black hole is the portal ....haha thats awesome..and it does sound kind of fictional...so im guessing your pretty far in the book too right?

You know how amazed i was when i came accross that! the idea that if you are able to dodge the singularity point of a black hole you would probably emerge from a white hole in possibly another universe! if u ask me thats crazy amazing! Personally i believe that dodging a singularity point would be quite possible and actually happen quite regularly, this is because of the fact that all the pressures around the object at the center of a black hole would be equal, kind of like the air pressure we experience here on earth, and that no matter how much force is on the object, a simple force rotating it sideways would move it equally just as if there was no force on it anyway, because the opposing forces cancel. I'm not sure if you understand what im saying, but what i mean is all you'd have to do is have enough horizontal velocity away from the center of the black hole, that the acceleration of the black hole wouldnt be able to pull you into the center faster than you reach the point of the black hole changing into a white hole, letting you pass the singularity point, sending you out the other side. Quite the journey id imagine .. almost makes you want to take up astrophysics

o so its not a portal to "the other worlds" jsut to another universe..aw thats not as fun

but ok has there been any real evidence that there really is a black hole? or has anyone ever seen one?

They have been found and are proven, but white holes on the other hand are theoretical. But i believe that they do exist, because as we know, what goes up must come down, just like in and out :D besides thigns that dodge the singularity point of a black hole gota come out somewhere

o ok so there real sweet....sooooo why dont they just send a big ol' camera into a black hole to see where it go?

I think the closest black hole to us is 1600 light years away ... so ya thats pretty self explanatory eh haha

yes “the closest black hole lies 1,600 light-years from Earth on the way to the center of the Milky Way in the direction of the constellation Sagittarius.” Since it would take 1600 years at the speed of light to get there and other 1600 years to get the information back to earth, it would be necessary to develop a super technologically advanced camera. Therefore, fiber optic cable would be just great since it carries much more data at incredible speed. However could fiber optic cable withstand prolonged radiation?
“The black hole, which is associated with a visible star called V 4641, is being called a micro-quasar because it exhibited for a few days in September the brilliant behavior associated with quasars. It sent out tremendous bursts of X-ray radiation and shot out jets of plasma at some 90 percent the speed of light”

i have a question. when we are looking up into the sky and see the stars. or when astronomers are looking at and studying black holes. all of which are VERY far away, is it possible that those things aren't there anymore. because the light we are seeing was emmited a long time ago, and by the time it reaches our earth is it possible that the objects aren't there anymore.

I think that, that might be a possibility.

I do think is possible that a star we can see from earth is not there anymore because we might still see the light it emitted, but the star might not be there. But regarding to black holes I don’t think so because light cannot escape a black hole. The gravitational field is so strong that the escape velocity (the minimum speed an object needs to have to move away indefinitely from the source of the field) exceeds the speed of light. That means they are not visible. So I wonder how astronomers detect black holes. I guess they rely on the large amounts of X-ray and ultraviolet radiation that they emit.

I don't think that there is any way to detect black holes yet. From what I have heard on TV and whatnot, the only way to possibly "see" a black hole is to witness it tearing apart a star or moving in front of one so that it blocks the light coming to earth. There are some really amazing pictures of entire stars being ripped apart and sucked into a black hole.

We cant see them but we know they are there. It is like looking for electrons.

i think that scientists measure and see black holes by emmiting a bunch of radiation and waiting to see if it comes back. Or maybe they can take a picture of space and where it is more black than usual they would assume it is a black hole... any other theories?

wow this is pretty contradicting lol...some of you say there are black holes..some say to far...some say dont exist? hmmmm

Black holes exist.. you can thank hubble for the pictures to prove it and the physicists that predicted and explained it. There behavior is the only gray area.. we can only assume.. but we know they are there. Quite the opposite from the quantum world eh.. maybe i just found the beginning of a theory of everything haha

I heard a theory that there is an enormous black hole at the center of our galaxy and that is why it appears to be "rotating". Also, what happens to all the mass sucked in by a black hole? Does it just dissappear or does the black hole get bigger?
If it were to get bigger wouldn't all the mass in the universe eventually be sucked in by black holes?

A black hole "shines" with Hawking radiation (thermal radiation thought to be emitted by black holes due to quantum effects) or (luminosity of the black hole). “The escaping member of a virtual particle pair carried away energy from the black hole, and the black hole loses mass as a result. Eventually the black hole loses all its energy, or equivalently mass, and evaporates”

The formula for calculating the lifetime of a black hole tells us that the lifetime of a black hole is proportional to the cube of its mass. That means a massive black hole takes proportionally much longer time to evaporate, and the process of evaporation accelerates as the black hole slowly loses its mass. So as the black hole loses its mass, its temperature increases. When a black hole gets very very small, its temperature may become so high that it may burn up and cause an explosion! Therefore black holes do not last forever so I don’t think all the mass in the universe will eventually be sucked in by black holes

But if there any numerous black holes and they all explode then wouldnt that leave our universe changed
some how.

i thought nothing could 'escape' a black hole

but it does make sense that they wouldn't live forever. if they did, then they would all gobble eachother up! the effects of the black holes blowing up or being created probably does not cause much to change on earth simply because the ones that are blowing up are really far away from us. its field of influence wouldn't be very strong say 100000 light years away from it. on the other hand, i was wathcing the discovery channel and apparently there are these ancient caves with pictographs that tell of a time that the sky lit up so bright that there was no night. scientists today believe that the light was caused by a star expanding out and collapsing on itself and then eventually for ming a black hole

If you sent a camera into a black hole, wouldn't it get 'swallowed up' or it dodges that point of singularity and emerges on the other side...so either way, we would have no way of retrieving it!

if black holes can "swallow" very large masses then where does this mass go. because accoriding to the law of conservation of energy "energy cannot be created nor destroyed, just transfered" so if a planet is sucked up by a black hole then just where does it go? another place in the universe? or if a star is ripped apart by a black hole what happens to all of the energy of the star?

oo! i just read this. what physicists and astronomers believe happens is that if the black hole isn't spinning and the planet or whatnot hits the point of singularity the matter will be compressed so much until it is zero volume. if the matter dodges the point of singularity the black hole creates a worm hole that will dump all the matter it swallows up into another time and place. and there are there are these things called quasars in space that they believe are the opposite as black holes. they are sources of unbelievable energy and light and have therefore been thought to be the other end of a black hole.

That is so scary. I would not want to get caught in that thing! What do you think it is like on the other end of the black hole?? I would not be a happy camper if I was spat out at another place and time. Do you think it would be possible to live in that new place and time? Or would you just die?
