whats at the other end of the black hole?????

Most of them have no other end, just a really havy star at the middle which hurts like heck to smack into :-). But for the few wormholes out there, some are indeed interdimensional, but trael trhough them is perilous, and we don;t know about the laws of physics on the other side. Some, though, are intradimesnional, with holes in the same place but at different times. Viola, time travel! But people could be in other universes, but odds are they won;t be the same.

Its a remain of a exploded star. After explosion, under it own gravitational force, it compacts so much that after certain point its escape velocity crosses the speed of light. So even light cannot escape from it. Thats why its called Black Hole.\nCheck out this URL and get to know more of this interesting thing of this Universe.\nhttp://en.wikipedia.org/wiki/Black_hole

Good, very good!!\nJaxon is very right.\n\nAdd few things:\n\n1. Black holes are the least understood entities and by nature human beings perfer to know about unknown.\n\n2. Neutron stars and black holes are closely related, they differ in amount of gravitational pull.However neutrn stars are visible and so are being reffered as a paddestal to understand black holes.\n\n3. As jaxon pointed out black hole may indicate end of univers: be clear, end of universe in terms of time not boundries or limits.\n\n4. Generally Black holes are present in the centre of glaxies so they help in understanding the creation of glaxies.\n\n5. As referred by jaxson about light: Be clear that the gravitational pull of black holes is so great that light can not escape out of a black hole.\n\n6. The postulate in the theory of relativity regarding deflection of light path under the influence of greavity is is witness near Neutron stars and black holes.

Recently, scientists are creating theories that saying there are more universes beyond our own. Until we learn to harnass the power of warpholes, black holes, etc. or send things traveling at the speed of light without damaging it, we may never know where space ends.

The spiral arms and the "halo" in the center, which is thought to be massive amounts of stars and light trapped in an extremly large black hole.\n\nAlso, there is evidence in super nova explosions that show the propable formations of large black holes and, eventually, galaxies.

A black hole is a singularity in spacetime. In other words, its a place where the stress energy caused by a gravitating mass is so large that spacetime curves to a single point.\n\nIt is not possible to know what happens on the other side of a black hole because all of the laws of physics are discontinuous at its boundary. Thats not to say that they change inside the black hole, its just to say that there is no experiment that can be done or observation made outside the black hole that can ever tell you what is going on inside it.\n\nFalling into a black hole is odd. As the gravitational field increases, time relative to places with a lower gravitational field runs slower. At the event horizon of the black hole (just before you fell in) the escape velocity is the speed of light, and so it would be akin to travelling at the speed of light (which is impossible). Time for you would extend infinitely, even those outside would see you fall in.

I found this interesting article about an ancient black hole scientists have located near our solar system.  They determined the exact route and speed at which this monster has been traveling.\n\nConducting a bit of astronomical archaeology, researchers have dug up 43-year-old photographic evidence of an ancient black hole and used the information to learn that the object has been wandering at high speed on an odd, looping path through the Milky Way Galaxy for 7 billion years.\n\nThe study, discussed in the Sept. 13 issue of the journal Nature, represents the first measure of a black hole's movement through space, said researchers involved in the work.\n\nThe object's travels take it above and below the main plane of the galaxy, where the Sun and most other stars reside and orbit around the galactic center in relatively orderly fashion. The wayward black hole zooms along at 90 miles per second (145 kilometers per second) relative to the Earth, currently carving an arc up and over our solar system.\n\nIn pinning down the vagabond's trajectory and piecing together a picture of its past, researchers say they are adding pages to at least one chapter in the book that explains how the galaxy formed. \n\nThe object is estimated to have been around more than 2 billion years before our Sun was born, a time when the Milky Way was a toddler of a galaxy.\n\n"We believe that hundreds of thousands of very massive stars formed early in the history of our Galaxy, but this is the first black hole remnant of one of those huge primeval stars that we've found," said lead researcher Felix Mirabel, an astrophysicist at the Institute for Astronomy and Space Physics of Argentina and the French Atomic Energy Commission.\n\nAccording to what I read, I would have to assume that the rate and speed at which a black hole travels has much to do with its' size.\n\nI would recommend you finish reading the article.  It is very interesting. Thanks for your question.

The mathematics of black holes shows that they might be able to transport you to another region of space or possibly another universe. However, the mathematics also shows that the connection only lasts for a fraction of a second at a time, and that the link to other universes depends on a specific set of conditions which scientists do not believe to exist. Even if it were likely, however, the strong gravity field of the black hole tears apart any material falling into the hole so it would not come out the other end of the Black Hole looking anything like how it went in, so in other words you would  have to really want to make this discovery because you’re going to die trying.

A singularity in which normal laws of physics break down.  It is a supposedly infinitely dense point in space.  There is no other side, although what happens within the even horizon is the most interesting part of the black hole, that is between the edge and the singularity.

Yes........more or less. A Black hole is a small view of what the universe as a whole will be like billions of years from now.

something like what we call a "black hole"

first of all, what u consider as dark matter is wrong. dark matter is not some hi-fi stuff which is highly radioactive or has some special properties. its just ordinary matter which cant be seen. secondly to ur question.. the outer limit of a black hole is called schwarzchild radius. when any matter approaches this limit, it cant escape whatsoever. ok, now our matter is in the black hole. first of all, 50% of the mass of the material gets converted into x-rays and other high energy radiation. of the remaining half, some part is used up in the fusion process, while the remaning part is used up in the expansion of the black hole. \nand because black hole is just an ordinary star with extraordinary high density, there is no such thing as a whilte hole. if u meant to say something like blackhole made up of antimatter which attracts matter and mutually anhilates, then may be ur question (2) makes sense.

Black Holes are strongly suspected to be responsible for a few powerful X-ray stars, and also to be at the center of most Galaxies - including ours.\n\nBut, while these are all much to far away for us to get to now - probably ever. You can see what the trip would be like with the Virtual Trips to Black Holes and Neutron Stars web page:\nhttp://antwrp.gsfc.nasa.gov/htmltest/rjn_bht.html\nand with the animations on the Falling into a Black Hole page:\nhttp://casa.colorado.edu/~ajsh/schw.shtml

What lies at the exact center of black holes is not known. Relativity equations point to the center of a black hole being what's called a "singularity," but that would be a point of zero volume containing infinite mass. Obviously impossible. As things now stand, our laws of physics simply do not apply to what the center of a black hole might be.

When all matter, including light and time, is sucked into a black hole, an infinitely dense singularity occurs. With all this heavy-duty cosmic attraction going on, something has to give, right? Enter white holes. \n\nPut simply, the idea here is "what goes into a black hole must somehow come out." If a black hole tears the space-time fabric of "our universe" creating a wormhole, a white hole would be the entry point into the "other universe." Essentially, a white hole would be the mathematical exist that emits matter n light just opposite to black hole

The center of our galaxy is obscured by dust and celestial bodies in visible light.\n   Longer wave lengths , infrared and radio waves give an unfocused view of the center.\n   The cosensus is that a massive black hole inhabits the center.\n   Astronomers have reasoned the existance of the black hole by the unusual movement of stars in that area.\n   Thier reasoning is quite persuasive but several points belie this reasoning.\n   The stars orbit the black hole in highly elliptical orbits slingshoting out at incredible speed.\n   A star is a sturdy entity in its place but would be very fragile and vulnerable racing past  a black hole.[Remember, some years ago,the comet that crashed into Jupiter,it landed in pieces because of the tidal forces on its last trajectory, broke it up]\n   These stars that seem to race past a black hole would shed most,if not all their mass and would not complete the orbit.\n   Then what is at the center of our galaxy? This may take some inovation,but it is not a black hole because black holes are nonviable entities.\n  They would be anamolies among celestial bodies.No upper limit to their size.\n   The surface would trap light at "C".THe quantum effect would allow a small percentage of photons to spiral outward.producing a slight glow in white light.\n   Anything that penetrated the event horizon would have to exceed "C"[Time dilation notwithstanding]\n   This would leave the other end of the quantum effect with slower than "C"photons,that could not spiral out could not spiral in and could not maintain orbit!\n   So what the heck is at the center of our galaxy??\n   The answer may depend on the question;What the heck happens to a neutron star if black holes do not exist??!!

The black hole does not emit x-rays. It is matter falling towards the black hole that gets accelerated to high speeds and releases x-rays.
