ok..plp did not get me...ok look....we have three jar's...1st small..2nd big...3rd large....now we can put 1st jar in 2nd coz..we have da place or space..and we can put 2nd in da 3rd coz..we  have place or space ....same way imagine earth we can put earth in solar system coz we have place or space in solar syatem...and we can put solar system in da milkyway coz we have place or space for it.and now we can put milkyway in universe coz we have space ..and if we consider universe 2 be da biggest space then! for universe 2 be there we need some bigger space..rite..some infinite space..and it will continue....no end 2 space....

People would take you more seriously if you wrote in proper English.\n\nYou have good thinking skills!  You are asking the right questions; keep it up!\n\nYour questions are dealt with in the field of "cosmology," which is a branch of physics.  Specifically, you are asking questions about the Theory of Relativity and the Big Bang.\n\nAccording to the Theory of Relativity, the structure of space is defined by the gravitational field generated by matter.  According to the Big Bang theory, everything began as an infinitely small, infinitely dense point about 13.7 billion years ago.  This point exploded, and continues to explode, so that matter and energy fly outward.  This is called "the expansion of the universe."\n\nWhen you put relativity together with the Big Bang, that means that space is expanding.  No one knows what space is expanding into, and at present, there is no way of knowing.  The Universe might be expanding into another, larger Universe, or it might be expanding into nothing.  This "nothing" is not a vacuum, it is litteraly nothing.  There would be no matter and no energy, not even gravity to give structure to the nothing.\n\nIs there an end to space?  If the Universe is expanding into nothing, then there is an end.  It is the outer edge of the gravitational waves being emitted by the Universe's matter.  Electromagnetic radiation would probably extend as far as the gravitational waves.  Matter would be lagging far behind the wavefront.\n\nIf the Universe is expanding into another Universe, then there is an end to our Universe; it is at the interface with the other Universe.  What this interface is like, is impossible to know because we have no knowledge of what the other Universe is like.  Suppose it is identical to ours, the same forces--gravity, electromagnatism, strong, and weak--and the same matter--hadrons and leptons. In that case, the interface would probably be a shockwave where matter was compressed by the advance of our Universe, but on either side of the shockwave, space would be continuous.\n\nBut suppose the larger Universe was much different than ours.  Who knows what kind of wild interaction takes place at the boundary?  It might be something mild, as in the case of a similar Universe, or it might be utter annihilation, or anything in betwee.  In this dissimilar Universe scenario, the space of our Universe would have a definite boundary, and on the other side of it would exist a different kind of space.  There is no sensible way to guess at what it might be like.\n\nNow, we have estabilished that if the Universe is expanding into "nothing" that there is a definite end to space.  However, if the Universe is expanding into something (another Universe), then, does space have an end.  Well, that is an unanswerable question because we have no knowledge of the larger universe.  Maybe it originated in a big bang, the way ours did, in which case it also has a definite ending.  But maybe it has always existed and goes on forever.  There is no way to know.\n\nYou are asking very good questions.  You will probably find it very interesting to read about the Theory of Relativity and the Big Bang.  Below are a couple of links and you can find a lot more by searching the Internet.  Your school or public library will have books on the subject, and of course, you can talk to your teachers.\n\nGood luck, and keep asking questions!

Just one doubt about your  theory,how do you know that only one big bang has taken place as you say that a second one is coming up???And tell me how you would accelerate something to the speed of light as the mass would become infinite.\nAnd according to your theory the total energy in the universe will go on increasing.You are stuck in a viscious circle!!!

From the physics point of view, our universe thus far is approximately 15 billion light years and expanding every second. Light year is the distance that light with the speed of nearly 300,000 Km/s travels in one year. This distance equals 9, 500, 000, 000, 000 Km (that light travels each year). Now, imagine how big our universe is!!\n\nAbout the second part, The space-time (space and time are inseparable) make our universe. They are both dynamic and the  fact that universe expands means both the space and the time expand. Now, in what do the space and time and our universe expand? This fact is not like other daily facts in our life, it is not possible to assign a place for space-time so that our universe expand in it. We cannot say there is something outside our universe because it is meaningless. These concepts are complex and require in-depth studies and deliberating.\n\nI hope these would be a little helpful...

If the universe is infinite, it doesn't mean that everywhere is the center, it means that it has no center. Or, if you mean relative to the existing matter...well, that isn't infinite, and has a defined center.

What is beyond the borders of the universe?\nIs it truly possible for the universe to go on forever? If there is an end, what’s on the other side?\n \nBefore we can address these questions, we must first define universe.  The word universe denotes all space and everything (matter, energy) contained within it.  The prefix uni means one.  The root verse means word, turn, or whole.  Thus our universe has traditionally been thought to be the one whole of all substance or matter.  Questions regarding our universe persist today.  Does it have a beginning and end, or does it go on forever and ever?  Is it linear or curved?  If it has limits of length or curvature, then what lies beyond the Universe?  If something lies beyond the Universe, then can’t we accurately call that the Universe?\n\nSome lay people and some scientists conceive of the universe as infinite space.  Others define the universe as finite, or limited (perhaps curved), space.  Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.\n\nGiven these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”  \n\nAs to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “Andromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”\n\nIn accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another.  Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.\n\nSome string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe.  Our zone, a “braneworld” could periodically bounce into another parallel braneworld.  This may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective.  Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.\n\nBeyond the borders of the universe, there are other universes moving through a multiverse.  While scientists do not commonly believe that our universe goes on for an unlimited distance, despite its present expansion, they allow for the possibility that the multiverse may go on forever.  If there is an end to our universe, what’s on the other side is called the multiverse.  If there is an end to the multiverse, another term may need to be coined to describe what lay people commonly refer to as infinite space.\n\nSteve\n:-D

Must have been some terrific star ship if one ship could help earth people kill everything in the universe.\nSince we can see out 13.8 billion light years, that's a heck of a lot of space to rocket around in to find everything to kill.\nBut since there are still some earth people left, maybe we'll just repopulate the universe.

read this.  http://news.yahoo.com/s/space/20060522/sc_space/towardimmortalitythesocialburdenoflongerlives  i think it WILL happen. and for me i WANT to live longer. I want to see our species travel beyond our solar system and find new life. Then i will be happier.

Well, its been theorised that what is beyond the universe is a fourth dimensional bowl. Basically our universe is a 3d soup encased in a four dimensional bowl. How was that made? I would think the same way that our universe was created. I mean, we have only just begun to comprehend the world around us, many of the theories that are coming out are exactly that theories because we really dont know. Untill we can explore more of our universe, we arent really going to know, and if its in a 4th dimension, we really wont know. But, what you could do, is look at some of the sources, and hopefully those will help.

I once read a theory that the universe is so big, that there's a chance that not only is there another earth somewhere, but there's probably so many that there's bound to be one exactly like ours.  The universe is huge beyond our present ability to comprehend, and it would be highly ignorant to think that with all the building blocks of life floating around out there that life doesn't exist somewhere else.  Whether we ever find it or not is another question.

Your thinking is good, but you have to take into account the distance scales involved. On the scale of the entire universe, space is indeed expanding, but on the relatively tiny scale of distances in our solar system, the expansion is miniscule. Also, the gravitational forces involved with holding the planets in their orbits around the Sun easily overcomes the expansion rate.

Thank you! Very informative (and correct) information!\nWell, according to Physics, the same vast quantities, dimensions etc., we have to the large scale, we also have to the small scale, going from our size into smaller (cells, moles, atoms, electrons, nuclei, ....)\nFurther, according to my theory, the Universe we described above is the connection between other universes! As a matter of fact, each one of us is a Universe greater that the one we usually talk about! After all, people discover the dimensions, Greeks named 4 of them and we, somehow think we understand them! People understand only what has been named! That is why we can not comprehend the other dimensions, since we have not discover how the Greeks named them!

Here's the flaw in your logic. You think that the universe has to be in something else to expand. The Universe is literally being created more and more. By this I mean the volume of real estate in reality is growing. There doesn't have to be something else that it's growing within. It sets it's own barriers and those barriers mark the current circumference of existence.\nBy the way, science does not respect theories. It respects laws.

Hmm, this one is interesting. I mean you could have left this one off with the science, but you added the philosophical point. But thats ok because it makes it so much more subjective. But, let's start with what science can prove, and move on from there. This should be interesting. Ok. Would the sun go supernova? No, because our nice little star is not massive enough, it needs A LOT more mass to go super nova. But what it will do is many years from now (hopefully) it will enter the Red Giant phase, where the Sun will expand outwards to about where Mars is. As it is doing that, yes it will burn concrete, it will flashboil the oceans, and turn our lush eden into a barren world shortly before being consumed by the sun. After that it will explode to create a planetary nebula and the suns inner core will remain and cool to a white dwarf. Now, the philosophical question. Mother nature would probably not step in because this is just another cycle, this happens to many other stars/ suns in our night sky. But, God probably would. In fact, he could come before our little star goes boom. Because remember that when he spoke to Noah, he said that he would destroy the world again, only with fire this time. So the sun destroying itself could have some part to play. But, he may not come till after it destroys itself. Now, that is if you believe the Bible. Im not sure what the Kuran or any other religious works have to say about their god or gods. Because remember, it took him from the big bang to about 35 A.D. to return, about 20 billion years. So, he may not come for another 20 billion years! Remember, his timescale is not like ours is. And thats the beauty of all this! He gave us a universe to explore, and a holy work commanding us to go forth unto the world and multiply! What better excuse to use for space exploration! I mean we have so much time that its almost insane. I feel that we have barely scratched the surface on our understanding of the universe, and that we should take steps to understand it.\n\n(Please note: Though I am a Christian, I respect other religions because last I looked, we lived in a country that allows freedom of religion, and actually, I would love to see some one from another religion answer this to see what they have to say about this)

There are _trillions_ of stars in the Universe.  Our galaxy, the Milky Way, is composed of 300 - 400 billion stars.  There are _billions_ of galaxies in the Universe, many dwarfing the size of ours.\n\nThe chance of other life _not_ being out there is so close to zero that it can't even be calculated.  There are infinite possibilities in this Universe, and we haven't begun to study more than a tiny bit of them.\n\nTo anybody that has the audacity to say "no" there isn't, then get an ego check.  We aren't the only intelligent life in a Universe of infinite possibilities.

It does not end and its growing, before you try tackling such a question, answer the micro-level questions of the same kind.  The universe encompasses all that exists, and by default then, it is largely unknown.  We don't know where the universe ends, and all evidence points to it being endless and growing, therefore we make a conclusion based on a portion of the information actually needed.

It is in all directions.  The expansion of the universe is happening at all points, so there is no center to be found, the reason why we see to 13.7 billion light years in all directions is that is how old the universe is, we can only see to distances that light would have travelled in that amount of time, hence a large 13.7 billion lightyear bubbles around us.\n\nSpace is expanding at all points, thus at each place in the universe this "bubble" will be seen - no one is at the center.

In spite of what some yo-yo answered, the universe IS expanding, but whether or not it's expanding inside something else is absolutely and totally unknown. In the far distant future our science might have progressed to a point where we'll have the means to answer that question. Instead of driving yourself goofy over wondering what our universe is inside of, best to just try and imagine an absolute and infinite void totally without space, time, energy, mass, or anything else.
