In All The Questions About The Universe and Blackholes What Are The Answers Helping Mankind With?
813276
Realistically? The search for knowledge has led to, or had a significant contribution to, the development of microwaves, radar, radio, superconductivity, computers, refridgeration, digital cameras, the internet and much more. When the theories that underpin most of these inventions were first discovered and tested, many people asked the same question - how does this help me? And then 20 years later some clever engineer invents a little box that heats up food. So give it time - almost every invention know to man once started as someone saying "I wonder how this works?"

its a MATHIMATICAL prediction that warmholes (or "shortcuts" in spacetime... so you fly into black hole and boom you're in another part of the universe or another universe all together) exists\n\nUnfortunatly this prediction bares no physical merrit as neither the black hole is capable of "letting things fall through" nor is a "whitehole" capable of existing for more then one instance (aside the fact that it cannot form, period)\n\nThe mathematical model is beautiful though, if you know much math I suggest you check it out.!

obviously, everything your father teaches you......\n\n\nalthough looking at you, i know what comes OUT of a black hole....\n\nyou wicked, naughty man-lookalike!!

Well, you're asking a question that has plague man since we looked up upon the stars and wondered who we are, where we come from, and what is out there?\n\nFirst of all, you're confusing some of the concepts that you've heard. Let's address your questions one at a time:\n\n(1) It is true that as we learn more about the Universe, we're discovering that the world is NOT as it superfically appears to be. A good example is that we used to think the Earth is flat, or that the Sun rotated about the Earth. These are superficially obseravable phenomenons, but the truth is very different. So now we're finding out many more new facts about the Universe that defies our imagination. For example, it turns out that the matter that we can observe through our telescopes, the stars, galaxies, etc. makes up only about 1% of what's out there in the universe, and we currently have no idea really what makes up the rest. We just call them dark matter and dark energy.\n\n(2) The Anthroptic Principle is basically saying that given all that we know about the universe, it can't be just  coincidence that it is capable of supporting life and particularly intelligent life like us. So the principle is suggesting that there must be some Agent (supernatual or otherwise), a designer, behind the contruction of the universe. Whether you believe this or not is up to you.\n\n(3) Here you should not pay too much attention. It is true that Quantum Mechanics (a branch of physics that tells us how microscopic elementary particles behave) saids that the outcome of an event depends both on the Observered and the Observer (hence the term "participatory universe"). But these rules only apply to electrons and photons, not people, stars and the universe. At least we currently don't have any evidence that it does. Also, I think all this is really more of a philosophical position than scientific fact.\n\n(4) I can't tell you whether the universe really exists or not. You will have decide that for yourself. But just remember, before you decide to jump off a building, make sure you are absolutely certain that you won't be falling down and breaking your legs.

The short answer is that whenever we take a good hard look at any given galaxy, we find good evidence that there is, or could be, a black hole at it's core.\n\nThe long answer is:\nIt is not so much a theory as something being increasingly noticed. Because black holes are the latest and coolest thing in astronomy (just look how many questions about them appear here!), everyone is always looking for them. They are not so easy to find because, well, they are black. You can't see one directly. One way to tell if there is a black hole there is by the effects of it's gravity on nearby matter. So far, the biggest effect observed on nearby matter has been high energy radiation caused by the rapid acceleration of that matter as it falls into the black hole. Some galaxies show that in their core, indicating a massive black hole there.\nAnother effect is that stars could orbit the black hole, just like the Earth orbits our Sun. We have known for a long time that all stars in a galaxy are orbiting around the center of that galaxy. IN the past it was assumed that there were enough regular stars and dust and gas in the center of the galaxy to make a mass big enough to orbit around. But recently observations with more powerful telescopes of stars closer and closer to the center of our Milky Way galaxy have shown stars VERY close to the center of the galaxy orbiting VERY fast. In that case it is easy to calculate the mass of whatever it is that they are orbiting, just like we can calculate the mass of the Sun by knowing how fast the Earth orbits it. Those calculations show the mass is millions of times more than the sun. Now we know all that mass has to be in an area smaller than the orbits of those stars, and the size of those orbits is measured as being quite small, so we know the volume far too small to be a big star cluster or other ordinary concentration of mass. The only known way to get so much mass in such a small volume is a black hole.\n\nI recall many years ago, when computers were just becoming powerful enough to do big simulations, that someone tried to simulate a globular star cluster by programming a few thousand stars to orbit in a big ball with no mass other than the stars themselves. It didn't work. The stars kind of just all dispersed at random and did not stay in a nice ball shaped globular cluster. Now it should be obvious that if there was a massive black hole in the center of the globular cluster, then all the stars could orbit it like the planets do the Sun, only not all in one plane like the planets do. And I believe some evidence of medium large black holes has been found in some globular clusters recently by the same method of using powerful telescopes to look at the orbits of stars very close to the core. And after all, what is a globular cluster but a really small galaxy.\n\nSo giant telescopes, some of them is space, are providing data never before available that just makes it more and more reasonable to assume that all galaxies have a massive black hole at the core.

According to Stephen Hawking, black holes are real and I believe that the Hubble telescope has found some way off in space.  Read Hawking's books and he explains them in a very straight forward, every man can understand style.

hows does knowing where the universe come from help you at all? the whole question is unrelevant... its exists, thats all you need to know... the probably with humanity is that we are so focused on where we came from, not where we're going...

Right about what?  \n\nThat space aliens started human life?  That some day the aliens will return and take him away to a new and wonderful planet?\n\nRight that helping someone is a bad thing?\n\nInsane people also bring me joy too but on a different level.

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.

Kentrell, I want you to look at this Nova website, and to watch these videos, OK?  I did, and was quite impressed with them.  they use infrared X-ray telescopes to look to the center of our Milky Way galaxy, with very clear images!!\n\nhttp://www.pbs.org/wgbh/nova/blackhole/program.html\n\nI believe you will like these, will learn from them!

"Singularity\nAt the center of the black hole, well inside the event horizon, general relativity predicts a singularity, a place where the curvature of spacetime becomes infinite and gravitational forces become infinitely strong.\n\nIt is expected that future refinements or generalisations of general relativity (in particular quantum gravity) will change what is thought about the nature of black hole interiors. Most theorists interpret the mathematical singularity of the equations as indicating that the current theory is not complete, and that new phenomena must come into play as one approaches the singularity.[15]\n\nThe cosmic censorship hypothesis asserts that there are no naked singularities in general relativity. This hypothesis is that every singularity is hidden behind an event horizon and cannot be probed. Whether this hypothesis is true remains an active area of theoretical research"

Might be better to be more specific and tell us the question.  It is hard to just give you information on space - seeing as it is infinite for starters.

This is not a cheap answer because this is a fact: No one knows yet where black holes lead to. Science has not yet found an answer to your question. \n\nIf you want more info on black holes, visit www.nasa.gov

Black holes don't have a purpose they just are!\n\nHowever Wikipedia gives\n\nA black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it except through quantum tunnelling behaviour (known as Hawking Radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can let one exit a black hole. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.

Love.  \n\nI believe it is the answer to the universe as well.

Sorry to Sun of Samsa.  I meant to give you a thumbs up!  The Black Hole Singularity is infinitely small (infinite density and ZERO volume).  The effects of the hole can be miles or light years across!

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.
