What process caused the Big Bang?

Here is the most complete explanation I've found (and no, "God did it" is not an explanation).\n\nAccording to string theory, there are ten spacial dimensions (plus one for time).  A dimension is simply a direction (Left-Right, Up-Down, Forward-Back, etc.).  Before the time of the Big Bang, all of them were extremely small with virtually no room for matter to move around.  Seven of them are still that way today.\n\nAt the time of the Big Bang, the natural quantum fluctuations dictated by quantum mechanics caused the three spacial dimensions I mentioned above to expand very slightly.  Although gravity always attracts particles together over the enormous physical distances we can see today, when all matter is compressed together in one tiny point it causes gravity to become REPULSIVE.  This is shown by the equations of string theory.\n\nWith all matter in one location pushing against each other, the three dimensions that were slightly stretched were forced to expand outward extremely rapidly.  This is what we now refer to as the Big Bang.

Big Bang is a theory that tries to explain the formation of the universe, its galaxies, its stars and planets etc.\n\nIt says that the Universe was created by an explosion of a Primeval Atom thus causing it to expand and move away from each other. This was actually based on the Hubble Law which says that Galaxies around us are expanding at speeds directly proportional to their distance from Earth, based on the observation of Edwin Hubble, 1929.\n\nIts a huge topic with lots of technical arguments and counter arguments. Here is the link that will satisfy your quest on Big Bang, atleast for starters...\n\n.:Fishie:.

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" is theroy that does not have to include "smoke".  The idea is that life may have started with "contact."   This could have been as small as two atoms that touched.  \nYour question assumes to many factors as facts for a complete answer.

God created Earth and it underwent some processes.\nGenerally people use the theory of Big Bang.\n\nBased on my observations, this type of question is most likely to get little response.\nWhy?\nBecause people do not know about how Earth was really created. So do I.

A very specific phenomenon called decoupling (specifically the decoupling of the strong force from the electroweak force) generated what amounted to a phase change in the nature of space-time.  This drove  a rapid superluminal expansion called "inflation" or The Big Bang.  Look up inflation on wikipedia.\n\nYou are correct that the universe was expanding just because it was a hot dense ball, but that is only a small part of the story and does NOT explain the expansion we see today.

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

Silicon was not formed directly after the big bang.  After the big bang, pretty much the only material in the universe was Hydrogen.  This Hydrogen coalesced into stars and began to fuse into heavier and heavier elements.  Eventually, heavy enough nuclei were fused together to form Silicon.\nThe vast majority of all observable matter in the universe is still in the form of Hydrogen, the heavier the nuclei, the harder it is the produce with in a star and the rarer it is in the universe.

Good question. There really is no good answer except to say that the basic equations of physics have a lot of symmetry. To get that symmetry requires there to be only a handfull of truly elementary particles. The Big Bang has nothing to do with this. It wasn't an explosion in the conventional sense and didn't 'break up' matter into the fundamental particles. It's more like the fundamental particles 'condensed' out of the vacuum.

There is a theory that the big bang was a result of a collison of two other universes. Say there is this sphere and inside this sphere there are other gelatinous spheres, these are the other universes, and two collided in a way that they created a big exlosion, which is the Big Bang.

Time was born along with space and energy in the Big Bang. \nSo, it has no sense at all asking for the "cause" of the BB. Causes precede effects in time. But there was NO time before the BB. Even the statement "before the big bang" is flawed. But our linear minds find it very difficult -if not impossible- to conceive.

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.

This happened in three ways.\n1) at the time of the Big Bang the matter was very dense. Because of this about a quarter of the available protons got changed into neutrons. These fused with protons to make principally Helium, heavy hydrogen and a tiny bit of Lithium.\n2) this mixture ended up in the first generation of stars.\nDuring their lifetime hydrogen was again fused mainly into helium, but also heavier stuff, like oxygen, sulfur and a few more elements upto iron\n3) the bigger stars of the first and later generation explode at the end of their life, when there is no longer enough fusion going on in their cores for lack of elements to fuse. The supernova explosions produce a lot of neutrinos. Neutrinos are capable to transmutate elements into others. In this proces all the elements are produced even the ones heavier than iron.\n\nHow do we know this?\n\nThese three processes can be modeled and calculated on computers. These models give predictions on the amount of helium and other elements produced in the Big Bang and in supernovae. These predictions can be checked against the actual abondance of the elements in stars, in the solar system and in the earth's crust.

In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago

I dont know. Stars forming quickly doesnt disprove big bang. the bang did not make stars. I guess it spread the compounds that stars form out of around. I also wonder at the 'quality' of a star that forms really quickly. But everyone knows big bang is hooey. Odin make the universe from the body of the slain frost giant, Ymir. They should teach that in school.

Science at this point does not know what caused the big bang. Or if there were multiple big bangs. \n\nBy the way, evolution has nothing to do with the big bang,other than they are both governed by natural laws of the universe (some have said these are God's Laws, or Maimonides equated these natural laws with angels, if that makes you feel any better). \n\n\nI have attached a paper on the big bang you might find enlightening.

There is hard, physical evidence that the Big Bang happened. There is NO hard, physical evidence that the god of the Bible existed, exists, or will ever exist.\n\nBUT..! Belief in a supreme being of some kind is a logical belief that can exist right along with the Big Bang. Most physicists and cosmologists agree that there are no physical (as in physics)constraints that can disallow a Big Bang. Something from nothing happens constantly in the vacuum of space!!!!! At sizes smaller than a proton, so-called virtual particles pop into existence all the time. Quantum physics has shown that at these infinitesimal sizes immense amounts of energy exist which can easily "produce" new matter from nothing. The bottom line is that these physical laws exist, and the next question any reasonable person would ask is who or what made these laws, the same physical rules that make a Big Bang possible?
