stephen hawking has said that balck holes indeed behave like black bodies, emitting some radiation, usually gamma and x rays. \nAlso, when matter falling into the black hole causes the black hole to spin. This creates a magnetic field like that of Earth's, emitting the high energy particles in the form of jets through the north and south poles of the rotating blackhole.\n\nSo, some kind of info might be released from a black hole, thats if the spaceship can detect these signs.

Most people *don't* believe galaxies are black holes.  A black hole is a region of space from which nothing can escape, even light.  \n\nSince you can't see a black hole (that light that isn't escaping), one has to rely on indirect evidence.  \n\n If you've found a large mass concentrated in a small volume, and if the mass is dark, then it's a good guess that there's a black hole there.  \n\nIt'll be quite some time before we can get "hard evidence" of a black hole.  We don't even have "hard evidence" that those are stars; it's just indirect evidence.

The reason we thought there was an object waiting out there tugging at Neptune was because we had bad data on the mass of the planet, when the Voyager 2 spacecraft reached Neptune we found out that our estimate was off by half a percent, putting the new value into our calculations (along with a bunch of other new values the Voyagers discovered) and running them resulting in a perfect match of the observations.\n\nSo to put things simply, there is nothing strange going on with Neptune's orbit and no reason to assume that there is a large body pulling on it.\n\nAlso note that Jupiter is not a star and not even close to being one so we can't claim to be a binary because of that.  It might be possible that there is a Brown Dwarf out there but we should have detected it with IR instruments by now given how close it would have to be.  A black hole might exist and if it isn't sucking in material would be almost completely invisible (and there really isn't much for one to suck in nor would we be in any danger), a neutron star or white dwarf I would expect us to be able to see if it were out there and if it formed in recent times we wouldn't exactly be here to ask about it.

The scientific consensus is that quasars are powered by accretion of material onto supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies. No other mechanism appears able to explain the vast energy output and rapid variability. So, we probably get Quasars when matter and energy are sucked into a black hole. What do you mean by "other side of a quasar."\n\n*edit*\nI think I understand what you are trying to say. A quasar (contraction of QUASi-stellAR radio source) is an astronomical source of electromagnetic energy, including light. So, the matter that get's in probably gets converted to energy.

Most of it does...\n\nBut what escapes has the correct direction and enough energy to overcome the Gravity well.\n\n\nThat would be Perpendicular and extremely high energy X-Rays...\n\nOther Radient energies can be emitted by objects entering the Black Hole rather than the Black hole itself.

I suppose it depends on what you mean by the 'other side'. \n\nDo you mean directly behind the sun, from our vantage point in space on earth? \n\nWell, there is the abstract answer, then there is the scientific one.\n\nThe 'bizarro-world' answer is that no one knows what is on the other side of the sun, because no one has been there, if we are talking about the side of the sun that is obscure to us. \n\nThere could be anything back there.\n\nBut, there probably is not anything lying close to the sun, if that is what you meant. The sun's surface is 6000 degrees centigrade. And the solar corona, the outer atmosphere of the sun, is one million degrees. Hence, nothing that we know of could survive in those conditions.\n\nUnless you meant the other side of the sun, in terms of the same distance away from it as is the earth. \n\nProbably, from a scientific standpoint, there is just empty space behind the sun. Space is very empty, and vast beyond human understanding.

A black hole, by definition, doesn't emit light; photons can enter the event horizon of a black hole, but cannot emerge from it. If you can't see a black hole, then how do you know it's there?? In order to detect a black hole, you have to be devious and use indirect methods. \nThe method of detecting dark objects by noting their gravitational effect on luminous objects is a very old one. \n\nThe planet Neptune was first discovered from its gravitational effect on the planet Uranus. \nThe white dwarf Sirius B was first discovered from its gravitational effect on the star Sirius A. \nA black hole can be discovered from its gravitational effect on luminous matter (stars and/or hot gas).\n\nIf a black hole exists in a close binary system, it can be detected indirectly. Gas ripped from the companion star will spiral in toward the black hole. As it does so, it is heated up (by tidal heating, and by friction as it rubs against neighboring gas). The hot gas emits X-rays as it undergoes its death spiral to the event horizon. (Once it's inside the event horizon, we don't see the gas any more, but it's highly visible as long as it's outside.) If you are hunting for black holes, it's good to start by looking for binary star systems which are also strong X-ray sources. \n\nAbout a dozen other black hole candidates, with masses up to 10 solar masses or so, have been found in binary star systems within our galaxy. (We don't expect too many black hole stellar remnants, given the scarcity of the extremely massive stars which are their precursors.) \nAn interesting recent development in astronomy is that supermassive black holes (that is, black holes more than a million times the mass of the Sun) are found at the centers of many galaxies. Our own galaxy, for instance, has a black hole with mass 2.6 million Msun at its center, 8000 parsecs away from us. Our own galactic black hole is actually fairly wimpy. The Andromeda Galaxy, 700,000 parsecs away, has a black hole with a mass of 30 million Msun. \n\nHow do you go about hunting such supermassive black holes? As usual, you go about it indirectly, by looking at the orbital motion of gas and stars near the centers of galaxies. For instance, the observation of stars near the center of our own galaxy has revealed that they are orbiting a massive object with M = 2.6 million Msun. The closest star to this massive object comes within 17 light-hours (120 A.U.) of its center. The only plausible way to cram 2.6 million solar masses of stuff into a sphere 120 A.U. in radius is to make it all into a single big black hole. (For instance, if you tried to make a cluster of a million neutron stars 120 A.U. in radius, the collisions between neutron stars would make them all merge into a single big black hole within a few hundred thousand years.)

In that picture you are viewing the very bright hot disc of matter spiralling around the black hole. It's called an accretion disc. The black hole is actually at the centre of each disc and is invisible. The accretion discs are far enough from the black hole's influence for the light from them to be able to escape.\n\nYou can't see the black holes; you can see the influence they have on the gas around them.\n\nA previous answer claimed that it was a false-colour picture. While this may be true, bear in mind that some electromagnetic radiation MUST have been intercepted by the telescope or there would be no picture at all.\nThe above picture was probably taken in the x-ray spectrum, since the very hot accretion discs are visible.

Good question - there are so many places a black hole can take you. For one, to your death. A black hole is a "gravitic" (is there such a word even?) pull in space that attracts everything including light. It is said that the force from within the black hole is so strong, that if a person were to enter a black hole - they would be ripped apart or quashed to death. Something like that. I'm not really sure, coz' I've never been into a black hole... =p\n\nThe other idea is, a black hole is actually sort of a teleporter or waypoint from one part of the universe to the other. It's like walking through a door only to find yourself on the other side of the world. If that's true, then the black holes are just shortcuts for us to access any part of the universe in a split second. Unfortunately, no one dares or wants to gamble their life by jumping into a black hole (which also by the way, the nearest could be a couple of light years away). Besides, if you entered a black hole and found a cooler planet on the other side - would you want to come back? I think not.\n\nSo it boils down to this - do you think that you can jump through a black hole to appear on the other side of the universe? Find a new world? Or do you think you'll be torn to pieces? The choice is yours. For now, there isn't a definite answer. But think the Bermuda Triangle and you've got your answer... =p

you should see the nova on blackholes, it was on last week\n\napprently only to much can actually get to the center at a time, and most matter/energy gets bounced around within the event horizon, never to escape, but not actually getting all the way in\n\nand anyway blackhole emit particles of hawking radiation and would eventually expell there mass and kinda evaporate away\n\nand if one black hole had the whole universe in it, sounds prime for  big bang to me

Travel close to the speed of light or get really close to the event horizon of a black hole.\n(Well, you DID ask it in the physics forum!)\n\nIf you just want to relax, why not spend some time on Yahoo! Answers!!!!! It's fun.\n\n\n:)

Interesting.  Since muons, even at near-light speed, are likely to decay before hitting Earth-local detectors, it seems difficult to believe that any have been detected.  At least I've seen no articles on muon radiation from black holes in the major science publications.\n\nAlso, if you were indeed a walking black hole, the circumference of your event horizon would probably be comparable to the size of a proton or maybe smaller.  In which case, you wouldn't really be walking or typing or reading this answer.  <sigh>.\n\nAnd we even shouldn't go anywhere near considering the effects of stellar-equivalent energy flux around your navel.  Does the term "massively extra crispy" begin to communicate the state of your body not to mention your surrounding area for miles?  Thought so.

There is no boundary as such because there is "nothing" beyond the edge; but the Universe in not infinite.  Difficult to get your head around I know especially as "nothing" in this case does not mean nothing as you understand it now.  If I go on you might blow a fuse so I will stop there.\n\n[re: above - "The Milky Way" is the name of our Galaxy not our Solar system]

If the Andromeda Galaxy is 2.5 million light years away and it's the only galaxy on Earth to be seen by the naked eye, it leaves us to wonder how far it really is.\n\nPersonally, I googled it. I couldn't find a thing relating to the blank nothingness further than the universe.\nI only looked a little bit, but there are very few educational guesses on the Internet.\n\nMaybe you should try. Googling that is. Maybe it's you who'll find the right words to search it in.  \nThe words stumped me so the was probably my problem.\n\nGood luck on finding the answer!\n-Marissa

i'm not sure at all(I don't think anybody is), but i think that there might have been other big bangs. Maybe the universes are linked by black holes?

A very good question but one that we don't know the answer to yet.  It is a hypothetical situation that could create a wormhole or perhaps the center of a blackhole is where this kind of phenomenon occurs.  The bottom line is that there is no hard evidence of this but it seems possible according to mathematical models.
