the begining/end of the universe?

There appears to be a birth and death cycle within galaxies, evidenced by the black holes found in the center of many of them, including our own.

The 'End' can only be a new 'Beginning'.\nSo, why worry ? Be Happy !

well let us take a "logical" look....the big bang says that there was nothing, then something, and now everything is expanding away.  So how did things get farther away than time has permitted?  Hmmm...kind of a hole in the theory.

Scientists say it is expanding. If true, that would mean that the universe is not infinite. It also suggests a beginning.\n\nGood question. Reminds me of my childhood imagination. I imagined a brick wall at the very edge of the universe. Then, however, I wondered what was on the other side of that brick wall.\n\nI wonder what the scientists are saying about it? I bet they don't know either.

Everything started off with The Big Bang. As there is the Big Bang Theory, there is also the big crunch theory if im not wrong. During the Big Bang, the universe is formed and it is expanding. But scientific discovery have showed that the Universe is expanding at a decreasing speed. It will come to a point of time where the Universe will stop expanding and due to the internal gravitational force, the Universe will also start contracting but at a slow rate. It will be really contract really slow at first but the rate of contracing will speed up. Think it as a exponential curve. Yup... Then everything will be suck back to the point of sigularity again and when energy in it becomes unstable it will explode again thus forming the new Universe. But anyway we wouldnt be ard to witness this by then. Not even a million lifetime. HAhahah... So dun worry!

The world is comming to an end?

December 21, 2012.  But it doesn't say the world will end... it's just marked as an important date, possibly the end of "a creation", but it's not at all clear what they thought would happen.  And the math is arguably way off.  Check the article I've cited from Wikipedia, it's impressive and thorough.

The Big Bang \n\nAbout fifty years ago, American astronomers studying the galactic star clusters, stumbled on evidence that the entire Universe is blowing up before our eyes. According to their observations, all the galaxies in the Universe are moving away from us and from one another at very high speeds, and the most distant are receding at the extraordinary speed of hundreds of millions of miles an hour.\n\nFirst there was nothing and it blew up and then there was everything and scientists have calculated that it all happened in 1043 of a second. [The] echo of that explosion can still be heard bouncing around in space. Scientists claim that in the big bang all of the fundamental particles necessary for life were formed. All of the complexity we see around us is the result of this massive explosion.\n\n"The new finding hit the scientific world like a thunderclap." It meant that the idea of an ultimate beginning was no longer merely religious dogma. Science itself now indicated that the universe burst into existence at a particular time in the remote past.\n\nIn 1992 measurements by the Cosmic Background Explorer (COBE) and by the Hubble Space Telescope seemed to confirm beyond any reasonable doubt that the Big Bang cosmology is indeed correct. George Smoot, Professor at the University of California at Berkeley and Principle Investigator of the COBE team which made the discovery, said regarding these new observations, "What we have found is evidence for the birth of the universe . . . It's like looking at God."\n\nWorking backwards, the evidence implies that there was a time when the universe was infinitesimally small. The evidence from general relativity also indicates that it was not merely a case of the matter in the universe being concentrated at a particular location, but that space itself was this tiny. At a sudden instant in time all of the energy and mass in the universe was located at this infinitesimally small point and exploded. The currently observed outbound motion of the galaxies from each other is a continuing effect of that explosion.\n\n"The scientific community is prepared to consider the idea that God created the universe is a more respectable hypothesis today than at any time in the last 100 years," Frederic B. Burnham, science historian, declared.\n\nHowever, some die-hard secularists propose that the universe goes through endless cycles of expansions and collapses. Hence, eternity becomes nothing more than an eternal succession of big bangs followed by big crunches followed by big bangs followed by big crunches over and over again and again forever.\n\nBut this violates the second law of thermodynamics, the law of decay, that implies that the universe is in a process of gradual disintegration - running down, like a wound-up clock. And if it is running down, then there must have been a time when it was wound up. Once the big bang takes place and the universe begins its expansion, entropy starts to increase. From this point on it will never be able to go back to its original state.\n\nWhat's more, the first law of thermodynamics (the conservation of matter) implies that matter cannot just pop into existence or create itself. And therefore, if the universe had a beginning, then something external to the universe must have caused it to come into existence - something, or Someone, transcendent to the natural world.\n\nThe facts clearly indicate that the universe is not eternal, and it cannot originate itself The implication is that the universe began at a definite moment in time, in a flash of light and energy. Science has begun to sound eerily like Genesis 1: "And God said, 'Let there be light"' (1:3).\n\nThe evidence requires that we believe God formed the universe at His command, pointing to the importance of taking God at His word literally - from the beginning both of time and the Bible. Second, there is such a striking parallel between the Hebrews 1

There are many questions that cannot be answered, yours are among them.  The end of the world is impossible to predict, and what will end it cannot be known.  I don't see anything happening too soon, so I woudn't worry about it if I were you.  The Sun won't explode, yet there will come a time -- so far into the future that neither you or I will have to worry about it -- that it will burn out.  God is merciful.  As long as there are a few of us who believe in God, He won't wipe us out.  I believe that God just let us on our own, to see how we handle his gift of the universe.

Nobody really knows for sure.\n\nThere's a theory that the universe is expanding in a spherical shape and will continue to expand until it reaches maximum entropy. At that point all of the energy and matter in the universe will be equally distributed and the universe will no longer be able to support life.\n\nThere's another theory that the universe will expand (again, roughly in the shape of a sphere) until all of the galaxies exhaust their kinetic energy. At that point the universe will begin contracting. When the contracting is complete a singularity containing all of the mass in the universe will form and explode in a big bang.\n\nIf you think about it, if the latter theory is true then it's possible that the universe has expanded and collapsed an infinite number of times in the past!

Quite an interesting question.  Well, it's true that the Universe is expanding, has been expanding since the Big Bang, and always will expand.  Plus, it's been doing so at the speed of light, so unless there's some way for us to travel faster than that, we're already too late to actually go (or send something) and find out what it's expanding into.  Point B can never reach the end.  Having said that, we're fairly sure that 'nothing' is beyond space.  Space is expanding into nothingness.  Of course, this is a hard concept since most of space has nothing in it anyway.  Yet even  when space is empty, it's still considered 'something.'  This empty 'something' expands into the nothingness.  Confusing, I know, but I can't think of a better way to explain.  Anyway, I don't believe there's a container that would stop the Universe from expanding.  I suppose it could be theoretically possible, but I'm not sure how.  I believe it will keep on expanding forever.

My current belief is that there was time before time as we know it. Something "had" to exist before the cosmos as we now understand it. The Big Bang wasn't the first, nor the last. In order for that to occur, yes, I believe that it was the result of a black hole to end all black holes reaching its limit. It's a thin, untested theory, but it is what I am with until something better is derived. This is consistent with my answer to your later question. That is I haven't thought about the possibility of one universe existing within another. It is plausible in my mind though and interesting enough to think about it for years to come.

Depends what timescale your talking about.  In our life times the universe's existence will be constant, but far in the future it will be likely to end.  Everything's relative, including change.

Latest scientific research suggests that the universe has no beginning or end, both spatially and temporally.  Thus, there was never a creation.

the same thing thats on this side. new matter is not being formed it is just expanding from the force of the big bang all those millions of years ago. Some scientists say the expansion will eventually stop and the universe will collapse onto itself, and then maybe explode again. All theories so in effect we dont know.

So far our observations are leaning more towards open, because our universe is expanding at an accellerating rate, and it shows no sign of slowing, if it were closed (which we havent found enough matter in the universe to help this theory) then the expansion would slow, come to a stop, and come back and collapse back in on itself. But so far evidence is telling us it won't.

There is nothing called the end of the Universe. There are three possibilities of the shape of the Universe.\n\nFirst, the Universe might have what we call positive curvature like a sphere. In this case, the Universe is called "closed" and it has a finite size but without a boundary, just like a baloon. In a closed Universe, you could, in principle, fly a spaceship far enough in one direction and get back to where you started from.\n\nThe second possibility is that the Universe is flat. This kind of Universe can be imagined by cutting out a piece of a baloon material and stretching it with your hands. The surface of the material is flat and not curved. You can expand and contract it by tugging on either end. Flat Universes are infinite in extent and have no boundaries.\n\nFinally, the Universe might be "open" or have negative curvature. Such Universes are also infinite in spatial extent and have no boundaries.\n\nThus whatever be the shape of the Universe, there is nothing called a boundary and hence nothing called the edge or end of the Universe.
