I heard that a black hole can suck in anything that comes to its way. And inside this black hole time is stopped and is considered just an object. And self-explanatorily, black holes are black! So is it possible that we are actually living in a black hole itself and why do you think so?

No, because if that were the case, none of us would be alive to talk about it.  Inside a black hole, the force of gravity is so strong, that nothing, not even light, can escape.  Once sucked in (to the black hole), there would be a time period of about eight seconds to travel from the outer regions of the black hole, to the singularity (black dot in the middle).  However, that time period is based upon our interpretation of time.  We see time as merely a basis on something else (the sun gives us a 24 hour day, the earth's rotation around the sun gives us our calendar year, etc).  This can get really complicated, so in a nutshell, if we were in a black hole, we would be moving at the speed of light, which is much quicker than the pace at which humans live.  That being said, when entering a black hole, time itself would actually speed up.  Once the singularity is reached, we would be crushed to an unbelievable density, making it impossible to live.  So to answer your question, we are not living in a black hole, although there is evidence of their existence in our universe.

By definition, something which cannot be detected does not exist (note: something that potentially COULD be detected, but hasn't been DOES exist; it just hasn't been detected).  For example, there can be large technological metropolis filled with aliens on a planet just inside of a black hole, but because we can never observe information from the hole, we say the city doesn't exist.  Same with the 'outside' of the universe.  If information can never enter the universe, than anything outside of the universe doesn't exist.  Such objects, the black hole city and the 'outside' of the universe, fall within the realm of metascience or philosophy.  However, just as we cannot prove they exist, we likewise cannot collect sufficient information to say that they don't, and it is this inability to test that makes it philosophy, not science.  PS: The black hole 'city' example was ridiculous, but it was more poetic than saying 'quantum particle' ;)

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.

The Black holes have so much gravity that they can suck up the planets with no power at all. You can imagin by this that not even light can escape through them. Black holes could be 3-D. \nSome Scientist thinks that the black holes can be used for travelling to other galaxies. We can travel through the Black holes at the speed of light to other galaxies within a very less time.

There are two posssible answers to this question. One is : The Universe and the other is : A Blackhole.\n\nBecause, within a blackhole, nothing exists - it is undefined. You cannot exist inside a black hole. Time ends within a black hole. To escape a blackhole, is difficult unless you travel in the opposite (reverse) direction. What escapes out of blackholes are antiparticles. You have the concept of space time wherein at a time you can have parallel universes. At the event horizon you can look out but cannot escape out of a black hole. Since time comes to an end in a blackhole, it is a finite time, you cannot escape it, so it is repeated diamay. \n\nIn the universe, nothing is black or white. There are shades of gray. The universe is expanding still but at a lower rate. There is no end to the universe and hence we can say that the space curves in a special way. Time and space both expand in the universe and it encompassed dark matter and black holes. Time in a universe can be thought of as cyclic if you consider that time has no beginning. You cannot escape the space. You cannot hope to reach the end of the universe.

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

Why would you think either a black hole or Earth would be made up of "pure energy" just because they have mass?\nMass is mass, energy is energy, only in very specfic circumstances does the line blur (E=mc^2).

*puts on cokebottle glasses*\nTechnically, black holes haven't been proven to exist, their existence is just extremely well supported, like the theory of plate tectonics.\n\nAlso, black holes don't actually move faster than the speed of light.  Nothing can move faster than the speed of light in a vaccuum. What you're probably thinking of is their gravitational pull is so intense that their escape velocity (the speed you have to be traveling at to break free of their gravitational pull) is faster than the speed of light.\n\nI think it's awesome in the biblical sense.  Black holes have always intrigued me- something that you can get stuck in and never, ever escape.  The way they distort light also is very interesting.\n\nI sometimes pretend that the inside of the event horizon of a black hole is where Hell is.  You can't escape it so you would be stuck there for eternity (the slow Hawking radiation notwithstanding) and you would be ripped up into your individual subatomic particles.  Plus, the rules of Classical Physics don't work in the way you would expect them to.\n\nCloyvin.

blackholes exist.AND the second one,we have energy stored i ourselves in chemical form which we can convert into mechanical form ,like when we run or do any work the chemical energy that we had a part gets converted into mechanical energy.After death chemical energy is still present there with decaying a part of it is being lost to the surrounding thus with time the energy content will decrease.

It wasn't Hawking who came up with the theory, but at the core of a black hole is a body of super dense matter wherein even the space between the nucleus  of an atom and its electrons has been compressed into nothingness.\n\nImagine all the matter that composes a large cruise ship occupying a space less than the size of a tear-drop.\n\nAll still theory, though the evidence has gotten pretty convincing over the last 60 years.

Not much actually as we still don't really have a clue what black holes actually are.\nThere are many questions to ask about the greenness of the black hole.. First, if the light is coming from the black hole itself then we actually don't have any black holes and everything we thought about them was wrong. \nScience is the art of guesswork based on what we already know. The term for this is called EMPIRICAL Science. Basically everything we are aware of is explained in this way.. When we make new laws or decided a black hole is a black hole, we are only guessing according to what we already know. \nIf you remember, people thought the world was flat, based on what they knew at that time. \nAnd the zeroth law of thermodynamics is called the zeroth because they had already come up with the first ,second and third before they realised they'd missed one..\nThe good thing about this is that essentially, this makes you just as smart as any of the top scientists in the world. Sadly, most of them would not share this point of view!!!!!

There's most likely not an 'other side'.  A black hole is a bunch of matter that's been compressed down into a singularity, or an extremely dense spot.  More stuff falling into the hole isn't going anywhere; it's just contributing to the density of the black hole itself.

Black holes are not holes at all.  These do not have any bearing on other universes.  They are just extremely massive objects that have collapsed within the Schwarschild radius and into a single point, which creates an area in space in which light could not escape if it gets so close.  \n\nAs for other universes, according to string theory we exist in a 3 dimensional subspace of a 13 dimensional universe.  Since we only occupy 3 dimensions, there could be other multi-dimensional subspaces which could affect our universe.  In fact, one theory of the big bang is that gravity from another universe and our own had caused them to touch, which concentrated energy in a single region, since energy is subject to gravity.  After this touching, the two universes went apart, and caused this energy to expand and 'cool' into matter that we know as our own universe.

To detect a black hole itself is not possible - what you can detect is the radiation caused by matter falling into the black hole. \n\nThrowing matter into a black hole converts matter to energy (e=mc^2) very efficiently, so when you can see point sources of hard x-rays or gamma rays in the sky with no obvious physical source this can be taken to be a black hole. \n\nThe other thing we can do is model how stars age. When all their nuclear fuel is consumed they change form. A star like our sun will convert to a red giant. If the sun were about 3 (?) times as heavy (this is known as the Chandrasekhar limit) it would collapse to form a neutron star. About 10 times as heavy and the matter inside would not be able to stop collapsing and you would end up with a black hole. We can detect this in binary stars where two stars orbit each other. If one star appears to be orbiting something we can't see we can work out how heavy it is and from that decide whether its a black hole or a neutron star.

The gravatational pull from a black hole is so strong that the likelyhood of an object being released is slim at best. The reason it is called a black hole is because gravity is so strong it even absorbs and disburses the waves and particals that make up light. Most scientists believe that even atomic coheasion is lost so that the smallest particals of the nuclious are torn apart.

According to general relativity, the matter inside a black hole collapses to a single point: a "singularity".  At this point, the mass density (ρ = m/V) is undefined (because the volume of a single point is zero). \nWe have a lot to learn about extreme cases such as this.

Nope.  Whoever told you this has been watching too much science fiction.\n\nBlack holes are just collapsed stars, and their gravity is no bigger than any other star (except to things that are very close to it).  There are enormous black holes at the center of galaxies, but these don't pose a threat to the majority of the galaxy ... and the earth is way out near the edge of our galaxy.  And there is no black hole even theorized that is big enough to swallow entire galaxies.
