To everyone who says the big bang never happened...?

1) At the present speed of light it could be bigger than that.\n\n2) Good point!

You're absolutely right, and the Big Bang has a remarkable way of not violating that law.\n\nExpirements have been done lately that prove that a particle, such as an electron, can be spontaneously created along with an anti-electron, or a positron. In the universe, both particles exist, both have mass, but should they colide, they would colapse into nothing-ness again. \n\nThe Big Bang could have been exactly such an event, but on a macro, or very large scale. Matter and anti-matter exist, and both might make up our universe. That satisfies the law of conservation of mass, as everything particle in the universe has an anti-particle. The net energy and net mass is zero.

You have to think back and ask the correct questions to answer this one. The theory of the "Big Bang" is incorrect. First Question: "Where did the matter come from for the "Big Bang"? Answer: "From somewhere else". Keep asking the question of "Where did something come from"? and you have to arrive at the fact that at some point, there was absolutely nothing.\n\nThis is a very hard concept to understand and think about because you always want to think in terms of a "void" if you try to think of nothing, but you have to realize that "a void" is "something" so you have to think of "nothing", "nada", "zip".\n\nThen you can arrive to the conclusion that...\n\n"It is the propensity for NOTHING to create SOMETHING".\n\nThe very first thing nothing would create is energy, something that would keep manifesting itself and propegate. That is what you would call "Life". Some refer it to "God" but it still all the same thing and exists everywhere in the universe.\n\nThis "Energy" would eventually become so extreme that it would create the "void", then the energy would transform into matter and gravity and begin to fill the void.\n\nThese three forces are the basis for all the laws of our current "Universe" and have dictated it's behavior ever since.\n\nThe universe if far older then the 13 billion years old we now can detect, it is constantly changing, expanding, and filling the ever greater void it creates as the energy, matter and gravity continues to be created.\n\nTo answer your question, you are sitting on it, it does not sit on anything.\n\nWhen your coporal body can no longer contain the energy that created you, as in all "living" things, your energy will again become part of this universe, no matter how trivial that energy may be, it is still a part of the entire energy that was and is still being created at this time.

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.

Question:  If matter cannot be created or destroyed,  \nwhere did the first(present)matter come from?\n------------------------------------------------\nThough, it is still a big question, if the "Big Bang" was\nreasonably symmetric the universe should have started out\nas pure energy, or as equal parts antimatter and matter\n(matter can be destroyed and turned into pure energy by\ncombining it with antimatter, and energy in some other\nform can be converted into equal parts of matter and antimatter).\nThe big question is, why do we normally only see matter around\nus, and not equal parts of both matter and antimatter? (Of\ncourse it would be pretty hazardous living around stuff that\ncould annihilate you!).  There are a bunch of theories, but as\nfar as I know, nobody really knows yet.

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.

Yes it all started with dark matter and energy that were under enormous pressure in a molecule and then the big bang was sparked because of this pressure building up. However what was before this and more importantly why it happened no one will ever know. I prefer to follow the scientific explanation of the origins of the universe as opposed to religious ones because it makes more sense and there is proof.

We do not know what came before the Big Bang.  There is no evidence/data yet to give us any direction.  There are many who think that that the Universe is eternal.\n\nThe fact that you ask "Who", implies that you think an entity of some kind created everything.  There is no evidence for that either.  In fact, insistence that there was a divine creator begs the question, "Who created the creator?"\n\nIf you answer that the creator always existed, then next question is, "Why couldn't the universe have existed forever?"\n\nOccam's Razor... which is the simpler theory?  Eternal universe or an eternal creator who created the universe?\n\n--------\n\nTo the Bat_Freak:  Wasn't it the Anti-Monitor and the Spectre?

Okay considering this scientifically (ie not just assuming there is a God) at the moment no one is sure how the big band happened. However the big bang was the start of time as well as space so it is difficult to talk about before. Some scientists believe that the big band was caused by tiny fluctuations of the vacume. Something like the universe can be forever just by never stopping or by time ending much as it began in a 'big crunch'. It is possible that there is something beyond the universe. M-theory suggests that there are many different dimensional universes floating around in a larger dimensional space. All of these are of course theories the point is to try to use these to make observable predictions which will either support or contradict the theory.

Why is it hard for people to believe that someone bigger than us created a masterpiece? This all leads into the question, Is there a God? If the big bang theory was true, what caused the big bang? I don't see things just happening all around me for no reason. When you plant a seed it grows. But you have to plant the seed first. \nBabies don't just happen. They have to be conceived. The point I'm trying to make is that if we have to react in order to get a reaction, why would it be any different from the beginning? Someone HAD to create us or nothing would be possible.

the big bang happened 13.7 billion years ago.  also, i have something else for you to think about.  the universe is 13.7 billion years old, yet we can observe parts of the universe that are about 46 billion lightyears away.\n\nhttp://www.sciam.com/print_version.cfm?articleID=0009F0CA-C523-1213-852383414B7F0147

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.

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,"

Who actually said that theres an 'end' to time itself?  Theoretically, who says that time hasnt ended before, and whos time are asking about, ours or someone else's? These are factors that have to be considered throughout the course of that which is the universe. Now, some scientists claim that another "Big Bang", much like the one that some believe formed the universe in the first place, will happen again and completely wipe the board clean.  The question you should be asking yourself is this:  If 'Big Bangs' keep, well um, banging, then who says that will end?  What if it already has happened several times, yet in your lifetime, you believe that youre still forging the original trail?  The problem with this question is that we, as stupid friggin humans, are basically incapable of having any sense of time. We live our and die, if we're lucky. But we dont know if another big bang will happen tomorrow at which point everything goes back to zero, history repeats itself and none of us are the wiser. Its a lot to think about, but as a simple answer to your question which is: 'When is the end of time?", I believe that the simple answer is "never".\n\n-J.

And there is a lot more where that came from. Scientist have proved the big bang did not happen( law [not theory] of conservation,of angular momentum)-but many don't want to hear that either. Moon-earth distance relationship, oldest dessert and tree, and coral reef all about -4400 y.  Theres is lots of 'stuff' that argues against an old earth.

First of all, the Big Bang theory does not address how the universe actually got started. It describes how the universe has been since that point. And it is remarkably well established for times after about 1 millisecond after things got started. The universe is expanding and went through a period of very fast expansion early on. The temperature has been decreasing since the start which was about 13.7 billion years ago.\n\nHow things actually got started is *much* more specualtive. There are two main ways that people approach this, but I want to emphasize that neither is actually part of the Big Bang theory and that both are *very* specualtive. We simply don't have the data to figure out what happened before that first millisecond or so.\n\nThe first approach is to point out that time itself is part of the fabric of the universe. It is not something idependent. Part of the nature of the Big Bang in general relativity is that it is a 'singularity'. An analagous thing would be to look at the north pole. This is a singularity in the coordinate system of latitude and longitude. You can't go 'north of the north pole'. In a very similar way, the time coordinate cannot be extended (in this approach) past the Big Bang. This means there is no 'before the Big Bang'. Time simply doesn't make sense at that point.\n\nThe other main approach is to say that the singularity predicted by general relativity doesn't happen because of smoothing out by quantum effects. This *could* allow the time coordinate to extend past the Big Bang (but it doesn't have to). In this scenario, the Big Bang was a quantum fluctuation that 'got out of hand' and underwent exponential growth becoming the universe. The beginning was random since such quantum events are random (this is known and established). However, there would be physical laws describing the probabilities of such things happening. In this approach, there can be multiple universes that don't interact and that have various physical properties different than our own.\n\nI hope this helps!

The Big Bang occured around 14 billion years ago, the earth didn't come into existence until about 4.6 billion years ago.  The earth did not exist when the Big Bang occurred, therefore the Big Bang could not have destroyed it.  \nThe name "Big Bang" is a misnomer, there wasn't really a "bang", the name comes from a nickname given by supports of the old Steady State Theory, which now has very little to no support.\nThe explosion cooled, allowing the four main forces of the universe (gravitational, the electromagnetic, the strong, and the weak forces) to split apart.  Matter finally arose out of the energy created by the "bang", forming a plasma of quarks, gluons, and leptons.  These finally coalesced into protons and neutrons (via the strong force), finally they formed atoms by uniting with electrons via the electromagnetic force.  \nMatter coalesced via gravity into star and galaxies.  Planets arose from extra material not bound into stars.  \nI think God caused the Big Bang, but he didn't just "bang" it into existence as you put it.  If he did, why did he spend three or four days on one little planet in the entire cosmos, and spend only a single day on the rest of the universe.  I think it is rather illogical.
