Something from Nothing, our Universe? XFixYourBrainX: "Don't imagine outer space without matter in it. Imagine no space at all and no matter at all. ... To the average person it might seem obvious that nothing can happen in nothing. But to a quantum physicist, nothing is, in fact, something. ... Quantum theory also holds that a vacuum, like atoms, is subject to quantum uncertainties. This means that things can materialize out of the vacuum, although they tend to vanish back into it quickly.... this phenomenon has never been observed directly."... PROBLEM! If nothing is something, it would seem to logically follow that there is NO nothing, there is only something! Well, problem solved, the reason we can't get something from nothing is because there never was a nothing, there has always been only something! But, what was the nature of the something that preceded our universe, that we mistakenly thought was nothing? Maybe we should do further research! a) One law of quantum mechanics states that the smaller the time interval, the smaller the probability for a quantum event. At the moment of the beginning, the universe's time interval is zero. (Time starting at the beginning event.) With a zero time interval, the probability for a universe to pop into existence through some kind of quantum event would equal zero. b) Another quantum mechanic law stipulates that the bigger the mass brought into existence through a quantum fluctuation in the space time-fabric, the faster the mass must return to the space-time continuum. For something as massive as our observable universe, the return time would be briefer than 10-120 seconds, an extremely short time, much less then the blink of an eye. c) Could quantum mechanical laws have been different when the universe was much younger than a fraction of a second? Yes, possibly they could. However, to date no physical evidence has been discovered for this possibility.  Riddler_This: I believe we did come from "nothing". However, "nothing" holds different meaning to different physicists. To string theorists it might actually mean "something" which is interpreted normally as another dimension, or multiverse, within and adjacent to our own universe. When breaking down matter into anything smaller than protons, or quarks, it's highly likely we would be dealing with different laws of physics. At least, if you believe string theory, you would. The nothing that our something came from, which is our visible universe we see now, is posited to have come from another universe, one that might collide with ours every X million years. Meaning there might have been one preceded before us, and thus there likely will be one after ours is destroyed. This is why instead of a Big Bang, the theory that it might have been a Big Bounce, is becoming more commonplace. franklin1950: nothing explodes creating everything . the posibility of the quantom leap was more or less proven when they monitored a subject [ proton/electron ???? ] ... in one place - in no place - in another place ..... something/nothing/something ..... and what of " dark matter " ? ???  otcclass2008: Sup_r: that is still the BIG question... no one really knows... there are a lot of speculation.... sunbox: We're probably living in the pocket of a mighty and selfish God (so tells me the little man in my head whom even says : take the axe, damn it! take the axe!) Aryaa: Big Bang: Theory about begining of Universe. Before 20th century, most people believed that the universe was static and unchanging; and -either universe had existed forever or -it was set into motion at some finite time. No one had suggested whether the universe was expanding or contracting. In 1929, Edwin Hubble made a landmark observation, while gazing at the sky, that where ever you look, the distant stars are moving rapidly away from us. In other words the universe is expanding. This means that at earlier times, objects of the universe would have been closer together. It seemed that there was a time about 10 to 20 million years ago, when they were all at exactly same place. Thus Hubble's observations suggested that there was a time called BIG BANG when the universe was infinitesimally small and therefore infinitely dense. Time it is assumed/accepted, had a begining at the BIG BANG. (in a sense that earlier times [before Big Bang] simply could not be defined.)

Your main topic is still in my thought process.  Goran: "Now that we all know that something cant come from nothing....the only thing left is thinking that something or a creator such as, 'God' created everything" Really? The only thing left is god? How convenient. Your math here is not adding up for me? First, who says there ever was nothing? XFixYourBrainX: For something as massive as our observable universe, the return time would be briefer than 10-120 seconds, an extremely short time, much less then the blink of an eye. Maybe that 10-120 seconds is stretched out in, "time" and is actually in billions of years, not seconds, but to the universe it would be in seconds and us it would be billions of years. This is something to think about.  LiptonCambell: >>>the only thing left is thinking that something or a creator such as, 'God' created everything into being. I'm sorry, but I feel such logic is both flawed and only exists to disenfrachise people who are actually looking for proof of how the universe began, rather than looking for proof to back up whats said in the bible. You logic is flawed because you state that its impossible for something to come from nothing- but then you claim that it definately happened, because God willed it. Why is it impossible for something to come from nothing, but its logical for something to come from nothing if God does it? Does the impossible become possible because you claim God does it? If something is impossible, then how did God do it in the first place? And if nothing existed, then how did God exist? You present your conclusions like its airtight, but all it does is create more and more questions, in an attempt to create a Christian spin on our scientific results. You do not present such a case to help create a better understanding of the universe- you presented it in an attempt to validate Christian beliefs, when no real causal connection exists.

At the moment of the beginning, the universe's time interval is zero. (Time starting at the beginning event.) With a zero time interval, the probability for a universe to pop into existence through some kind of quantum event would equal zero. Therefore it is IMPOSSIBLE for a universe to happen right? No proof behind this. (Post deleted by XFixYourBrainX ) Goran: Pokerman, your entire argument is based on assumption there was nothing. That assumption is very unlikely. Universe always existed. Then you are attempting to use quantum physics to explain how something could not materialze from nothing because there was no time interval!!?? Goran: (Pokerman)"...there logically is a God? Which nobody can prove or disprove Hes the Alfa and the Omega." (Pokerman)God never came from something or nothing...he has always been. If you claim there is something (including gods), burden of proof rests with you. It's stupifying to see adult people ask for figment of their immagination to be disproved. How would you disprove Santa Claus? Does it exist? Goran: Satanic, if I'm reading it right, your argument is that there can't be nothing without something. I don't think that's what Pokerman is saying. He's saying there was nothing. XFixYourBrainX: What Im saying is that from what Quantum Mechanics and Mathematics states that something can not come from nothing! 0 does not equal 1 haha, the number 1 is the universe we live in how did it come to be? XFixYourBrainX: Now with that being said to go along with a) example. Since the possibility of a universe to come into existance without having a preceeding something, there is only one other way that the universe came into being. Does anyone know how the universe came to be since the probability of a universe coming into being without having a something to come frome is zero? | Science Chat Room 1 Person Chatting Similar Conversations |
