If our universe was created by the so-called big bang, how were the alternate universes formed/created?

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?

The universe is believed to have begun with the Big Bang. However the term 'begun' is a bit misleading since the Big Bang created time itself. Thus, if you think about it, the universe began with the Big Bang but, at the same time, it was always there since time itself only started then!\n\nIF the universe is on course to collapse in the Big Crunch presumably the argument will reverse and time will come to an end.

Or God could have came from the Big Bang. Or God could have come when you banged your head big that one time. \n\nIf I was God and could do a Big Bang, I would be doing it all day long. What a show.

The earth came into existence by some as yet undetermined process, the most likely of which was a "big bang" whereby all existing planets and solar systems began to form into their current transitory states. During that process, animal life began to form on the earth, by yet another unknown process. The earth is currently in a state of transition that will eventually result in its return to the previous unknown condition that resulted in the "big bang."\n\n\n\nNow send me $5 or I'll put a curse on you.

God created it. It is endless and boundless....this is proven by the fact that our universe is continuously expanding.\nThe Big Bang is man's attempt to explain something he doesn't understand. It is false.\nWhy? well the answer is simple.....You can't have an explosion from absolute nothing.\nGod created the universe....a simple explanation with no holes in it.

First, let's take the Big Bang theories of the early universe.  I presume that's your reference.  Those theories begin with the state of the universe as we observe it today, and how it is changing (expanding).  Then they assume the physical laws which govern the physical behavior of the universe are unchanged.  Then they extrapolate into the past as far as imagination allows (currently 13.7 billion years).  This puts all the matter and energy of the universe into your extremely dense 'ball of mud'.  Then they try to check their calculations by taking this as the initial state of a simulation and see if they can get the result to look anything like our universe.\n\nThat's certainly speculative science, but it is science.  But it addresses the origin of neither the ball of mud nor the laws of physics.  Big Bang theories do involve chaos and chance, but they don't say the laws of physics came from chance.  They just are what they are.\n\nSo, where did the ball of mud and the laws of physics come from?  "God created them." is the only answer that's in any way satisfying.

The other possibility [besides the Big Bang] was Fred Hoyle's steady state model in which new matter would be created as the galaxies moved away from each other. In this model, the universe is roughly the same at any point in time. It was actually Hoyle who coined the name of Lemaître's theory, referring to it sarcastically as "this 'big bang' idea" during a 1949 BBC radio program, The Nature of Things, the text of which was published in 1950.

this is actually a common misconception about the big bang.  the universe may be something like the two dimensional surface of a sphere.  it is finite yet has no boundary and no center.  nothing exists "outside" the universe.  to quote a dead writer, "there is no there, there".\n\nread this:\nhttp://www.sciam.com/print_version.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147

No one anywhere has the answer to your question, or even if there was any "thing" before the Big Bang. The religious crackpot fundamnetalists certainly don't have the answer! By definition, the universe is everything there ever was, is now, or ever will be. At the instant of the Big Bang, all space-time and energy that will ever exist was created.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com

The Big Bang theory is the most popular one. It is hypothesized that the universe was a collection of dust and other particles forming to one huge mass, until heat and gases formed and pressure from gravity and mass caused it all to erupt in one "big bang" causing everything to project and very high speeds in all directions.\n\nOur world was theorize to have originated through this process. The debris and particles that were projected from the point of origin (now the sun) and locked into its gravitation rotation. The larger mass debris attracted other smaller debris by its gravitational pull to form an even larger mass.\nThis mass growing in size of gases, dust and other particles started to alter by factoring conditions such as distance from the sun and compostion of gases and such. Eventually providing the right conditions and atmosphere to form water which is the basis of life. From that life was made sustainable by the oxygen created by water and plant life... so a billion bunch years later we have our planet earth and the universe we live in surrounded by other planets and stars.\n\nThere are also legends and tales from various religions and cultures that tell the begins of our universe and earth. You'll have to look these up and see.

How did matter come to exist? Obviously, these are not simple questions and throughout our brief history on this planet much time and effort has been spent looking for some clue. Yet, after all this energy has been expended through the BIG BANG, much of what we know is still only speculation. \n\nWhat came before the Big Bang?\nThe standard Big Bang model is singular at the time of the Big Bang, t = 0. This means that one cannot even define time, since spacetime is singular. In some models like the chaotic or perpetual inflation favored by Linde, the Big Bang is just one of many inflating bubbles in a spacetime foam. But there is no possibility of getting information from outside our own one bubble. Thus I conclude that: "Whereof one cannot speak, thereof one must be silent."

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

The scientific theory is that the Universe started as a fluctuation of the vacuum. Such vacuum fluctuations make appear a small amount of energy, for a small time. \n\nNot so the Big Bang. That was a HUGE fluctuation. So big that a lot of energy came to appearance in the form of mass, elementary particles. These particles started expanding, before the vacuum could reclaim the energy.\n\nAnd it is still expanding today. 14 billion years later.\n\nNow for some speculation. Is our Universe the only one? Maybe not. The Big Bang was one big fluctuation, maybe other smaller or bigger, take place all the time.\nBut most of these fluctuations will produce Universes in which conditions are just not suitable for life.\nThe Universe we observe is by necessity one in which the conditions are just right for us to have evolved into Homo Sapiens capable of asking questions.

1. before the Big Bang there was nobody anywhere to observe anything\n2. A qauzilionth of a second after the Big Bang, the Universe had already more or less the present size. The entire Universe that is, the visual Universe is always bending into itself (proved by Einstein is his 'Cosmological Considerations on the Special Theory')

Evolution of Universe\n\nThe three main theories put forward to explain the origin and evolution of the universe are:\n\n   1. The Big Bang Theory\n   2. The Steady State Theory\n   3. The Pulsating Theory\n\n1. The Big Bang Theory: Le Maitre and Gammow proposed this theory. According to this theory, at the beginning of the universe, the whole matter of the universe was once concentrated in an extremely dense and hot (~10 12K) fireball. Then about 20 billion years ago a vast explosion (big bang) occurred. The matter was broken into pieces, which were thrown out with high speed in all directions forming stars and galaxies; which are still moving way from one another. According to Hubble's law, the velocity of recession of a galaxy becomes equal to the velocity of light at a distance equal of 20 billing light years. It means, the light rays from stars and galaxies, which are situated at a distance of 20 billion light years or more, can never reach us. Thus this distance becomes the boundary of observable universe. On account of continuous recession, more and more galaxies will go beyond this boundary and the will be lost. As a result of this, the number of galaxies per unit volume will go on decreasing and ultimately a time may come when we may have empty universe.\n\n2. Steady State Theory: Bondi, Gold and Fred Hoyle developed this theory. According to this theory, the number of galaxies in the observable universe is constant and new galaxies are continuously being created out of empty space, which fill up the gaps caused by those galaxies, which have crossed the boundary of the observable universe. As a result of it, the overall size of mass of the observable universe remains constant. Thus a steady state of the universe is not disturbed at all.\n\n3. Pulsating Theory: According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.\n\nWe will now see the theories of planetary motion.

Just check this link and go thru the following article also\n\nhttp://www.big-bang-theory.com/\n\nBig Bang Theory - The Premise\nThe Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment. \n\nAccording to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know. \n\nAfter its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory. \n\nBig Bang Theory - Common Misconceptions\nThere are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe. \n\nAnother misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. Back in the late '60s and early '70s, when men first walked upon the moon, "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy."3 The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing. So where and in what did the singularity appear if not in space? We don't know. We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we. \n\nBig Bang Theory - Evidence for the Theory\nWhat are the major evidences which support the Big Bang theory? \n\nFirst of all, we are reasonably certain that the universe had a beginning. \nSecond, galaxies appear to be moving away from us at speeds proportional to their distance. This is called "Hubble's Law,"

Under the current Big Bang model the center of the universe is nowhere.  Ok. You don't like that, then how about the center of the universe is everywhere.\n\nThe Big Bang was not an explosion, the term "big bang" came from early opponents of the theory.  Basically it was the creation of space itself.  Subsequently that space has expanded, it is not expanding from somehwhere, it is expanding from everywhere.
