The Universe??? the big bang theory?

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.

The theory of the big bang doesn't explain things before it. But usually it's believed that before the creation of the universe there was energy concentrated or concentrating to the critic point where it blasted and spreaded through universe. The Big Bang theory is'nt the only theory about the creation of the universe, only the most accepted, you could find very interesting and different ideas. I don't like religious answers because their principal argument is faith and since faith can't be proven or refuted, I don't think it can be used as a valid argument, sounds tautologic for me (in logic, tautology is an statement that is ever true).

We have plenty of evidence for the theory that the universe was created by the Big bang. The universe was definitely created by the Big bang. \n\nRegarding the theory that God created the universe from scratch, in view of the evidence for the Big Bang that is clearly nonsense and no-one with an ounce of scientific knowledge would accept it. \n\nAs to whether God created the Big Bang itself, and then let nature take its course - it is remotely possible. However, unlike the Big bang itself, we have no evidence for the claim that God created the Big Bang. For people to state this claim therefore is blind faith, and has no scientific worth. It is merely their opinion and is not evidence-based.

The big bang is the creation of the universe. Scientists have recorded an echo in space, it is the echo of the big bang.

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.

The discovery of  the universe expansion(doppler red shifted spectrum lines) was the source of the Big Bang theory (i think)\n\nBTW: this is a SCIENCE thread, all you Jesus Freak back off!\nthe theory of the Big Bang is compatible with the concept of a god.\nwhat was there before the big bang ..let there be light....BANG.

The Big Bang theory is a scientific theory in cosmology, initially suggested by Georges Lemaitre. It is essentially the most widely accepted theory about the universe's origin. \n\nThe idea is that the universe was created sometime between 10 billion and 20 billion years ago (current estimate ~13.5 billion) from a cosmic explosion that hurled matter in all directions. Before that point all matter was concentrated at an infinitessimal point, known as a singularity. \n\nThe idea was most strongly propounded after the astronomer Edwin Hubble (after whom the famous telescope is named) found in 1929 that distant galaxies in every direction are going away from us with speeds proportional to their distance, suggesting at some point they were all at a single point. The theory also predicted the existence of a cosmic background radiation (the glow left over from the explosion itself). and received widespread acceptance when this radiation was actually discovered by Arno Penzias and Robert Wilson in the 1960s.

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,"

Wow, what great questions.  Just so you know, we don't know the answer to what was before the big bang.  One idea is that our universe expands, then contracts on itself, over billions of years, and the whole big bang repeats over.  In other words countless universes preceded our own.

Our whole universe is considered a white hole through the Big Bang theory where it states that universe was created in a black hole.Basically, it's a hole that emits or releases matter. Kinda the opposite of a black hole. So depending on your logic white holes could exist.

Take into consideration the billions of stars in this galaxy. Then take into consideration the billions of galaxies in the local cluster. Then take into consideration the billions of clusters in the local supercluster. Then take into consideration the billions of superclusters in the local segment of the wall. Then take into consideration the billions of segments in the Great Wall. Then take into consideration the billions of walls in the Universe. It's even possible there's more than one universe! \n\nWhat do you believe? I think there is life out there. But are they sentient and advanced? Maybe. Maybe not.

The big bang theory makes several very specific predictions about what astronomers should find in the universe if the theory is correct.  One of these is the "microwave background radiation," the remnants of the period in the early universe when it first cooled enough for light to be visible.  The theory also predicts what that radiation should look like in terms of temperature, density, and fluctuations.\nA couple of Bell Labs engineers, working with a microwave antenna, had this persistent noise they couldn't figure out the source of.  After isolating it, and measuring it in various parts of the sky, they discovered it was this very background radiation that was predicted by the big bang theory -- and they weren't even looking for it.  Since then we've launced satellites that have measured the CMB (cosmic microwave background) across the entire sky at high resolution, and it matches the theory's predictions to a very high degree of accuracy.\n\nThat's just one prediction the theory makes that has been found to be correct -- there are dozens of others.  Go to your library and get some books on the big bang and cosmology in general -- too much to answer here :)

I am certain you have heard of the Big Bang if you can articulate the question as lucidly as you have.  See this month's Scientific American for an excellent article that delves into the latest expierimental evidence in support of current theories that take us back to the first millisecond of the universe.  This article is featured on the cover.  If you can't get your hands on it, send me an email to strangerbarry@yahoo.com and I'll scan / email it for you.

The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. \nIn 1927, the Belgian priest Georges Lemaître was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lemaître's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance. \n\nThe big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself). The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery. \n\nAlthough the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions.

The Big Bang Theory has not been proven. Don't believe every piece of hype that you read. Many predictions of BB and related theories have been verified. Many others have been contradicted. Same with some ID and Creation theories. Some have been verified, some have been contradicted. Many evidences claimed to support a billions-years-old universe also support other explanations. Usually it's just a matter of premises.

The Universe was created by an event known as the "BIG BANG" and has been increasing ever since.  There are many theories about what the universe will do in the future Ex. ever increasing, saddle shape, or will is contract and implode creating a massive black hole.\n\nVery cool and interesting stuff.\n\nCheck this site for more on the "BIG BANG"

If I were you, I'd search it myself instead of asking people, but that's just me.\n\nThere are so many theories to how the universe started, in which the Big Bang theory is the most popular. In this theory, it all started with a single point with the same amount of matter in the universe and it was really really hot. Then it just explodes, continuing to expand at an alarming speed. It was so hot that not even the particles that made up atoms could not even form until the universe was expanded enough to cool down, and then the first atoms were made. Then it just continues to expand to where we are now.\n\nThat's one theory. I like the never-started theory. There was no beginning to our universe. The reason why the Big Bang theory is the most accepted theory is because we (us humans) like to think that there is a start to everything. It just makes sense that there is a beginning. And it's easier to build theories and ideas upon it.\n\nPS Penguins!!!
