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.

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. This phenomenon is responsible for the existence of forces, that hold the Universe and matter together.\n\nNormally the bigger the energy fluctuation, the smaller the time it is in existence.\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\nThe Big Bang theory itself, doesn't say anything about the *cause* of the explosion. It describes only how the Universe evolved after the explosion took place.\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 philosophical questions.

Cheerleader101,\n    Let us go on a bit on the scientific track.  Have you heard about the famous 'Big Bang Theory'?  It says that the Universe was in the beginning a condensed mass which shrank and shrank inwards.  When it could now shrink any more becoming a condensed mass of great pressure, it burst and thus ever expanding Universe was created. This explosion of immeasurable magnitude is called by the scietists who formulated this theory as Big Bang.  \n    Let us now go on the track of Ancient Vedic Wisdom propagated by the Rishis(Indian Saints) of india.  About 4000BC, in the Upanishads, Rishis wrote:  "Asade Vedamagra. Thad Aseeth. Thadandam Niravarthathaya. Thad Visphotayatha. Rajatham cha Suvarnam Abhavath." This is Sanskrit which means :In the Beginning there was mothing.  From nothing existence was born.  And it became a round mass and it began to shrink.  Then when it could not shrink anymore, it exploded" .  This is the simple and plain meaning.  Great amount of explanations and details lie behind these utterances of Rishis.\n    I will write about this in detail later!\n         Mukundan Pallipravan

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?

It's known that dark matter existed before 'something' caused the explosion of light.\n\nSome scientist think that is was a build up of ions/neutrons or some such, which caused the 'bang'.\n\nMany also believe that, because the universe is expanding at a faster rate than previously imagined, some day the whole thing may return to a 'dark' state as galaxies travel beyond the reach of observation.\n\n(By that time, our Galaxy will have been swallowed by the black hole which is keeping it 'captured'.)

the complete concept of big bang is explained here... beginning to the end.\n\nWhat happened before the big bang, evidence of the big bang theory, what caused the big bang, big bang theory of evolution are some of the questions asked on the Internet today.\n\nWhat do we mean when we talk of big bang theory? It is in the last 30 years or so that scientists across the world accepted and confirmed the existence of the big bang theory. It has more or less been proved that the evolution of the Cosmos occurred with a big bang. There is no further denial on this fact of big bang theory.\n\nThis evidence put forward by the scientific community is further corroborated firmly by spirituality. How?\n\n\nLet us travel to the beginning of time when the Cosmos is in the process of complete dissolution. What happens after the complete dissolution of the Cosmos? In the field of the spirituality... everything contained in the Cosmos is but an illusion... an act of Maya (Veil of ignorance). There is nothing in the Cosmos which is solid in nature.\n\nBroken down to the basic building block of the universe... everything in the whole of Cosmos is a cluster of atoms and molecules. Then what constitutes the Cosmos itself? Spirituality spells out the truth... everything contained in the whole of Cosmos is but souls atmans and ether, the inert matter.\n\nEther is that dark black substance which fills up the void existing all over the Cosmos. Apart from ether spirituality defines the Cosmos consisting of souls atmans and nothing more. Whatever is visible to the physical senses of a human being nay every living being is limited to the use of the physical senses. Beyond the senses.... nothing exists in the whole of Cosmos except the world of souls atmans and ether.\n\n\nThe dissolution of the Cosmos is best defined in Bhagavad Gita, the sacred doctrine put forward by Lord Krishna in the battlefield of Kurushetra. As per Bhagavad Gita Almighty God is defined as, "the sum total of all the purified souls atmans in the Cosmos at a given point of time"! At the time of the dissolution of the Cosmos all the souls atmans in the Cosmos having purified themselves collect together to form what we know as God Almighty.\n\nThis collective power of all the souls atmans in the Cosmos... the size of half a thumb as detailed in Bhagavad Gita and unable to contain itself for long explodes with a big bang. And this big bang leads to formation of a new Cosmos... a new series of universes, galaxies, cluster of stars and solar systems.\n\nEvery new Cosmos can begin only after a big bang. No Cosmos can form without the big bang having occurred! The occurrence of the big bang announces the formation of a new Cosmos. It is the big bang theory which paves way for all the souls atmans in the Cosmos to start their cosmic travel of 8.4 million manifestations.\n\n\nThe big bang having occurred... it takes millions and billions of years before the system becoming conducive for life to germinate. As the conditions became conducive for life to germinate on Mother Earth... the souls atmans (within the gravitational pull of the solar system) settled on Mother Earth. This gave birth to life on Mother Earth.\n\nStarting the journey as an amoeba and finally culminating into the form of a human being... it is only as a human being that one reaches the end of life... gains enlightenment and finally salvation!\n\nThe big bang theory announces the start of a new Cosmos... the beginning of life for every soul atman on its cosmic journey!\n\n\nSpirituality or otherwise... the start of the Cosmos could not have occurred without a big bang. It is only the big bang theory which governs the start of cosmic system. There is no other means which could have led to start of a new Cosmos without a big bang.\n\nThe big bang is that phenomenon in the life of a Cosmos without which the existence of God Almighty himself would get negated. God Almighty being the sum total of all purified souls atmans

The Big Bang is not a theory of the earth's origin. It is a theory of the origin of the whole universe. The earth wasn't formed until about 8.7 billion years after the universe started.\n\nThe predominant views of the origin of the earth are all variants of the nebular hypothesis which states that a cloud of gas and dust collapsed forming the sun and the solar system. There was a period of intense collisions where the planets grew through accretion. Most of the volatile chemicals (hydrogen, helium) were blown away from the planets near the sun due to solar wind (which was more intense when the sun was young).

This question is completely confused. I have attached a web site about the big bang you might find useful.

It's a big mystery. I have read that initially, at the onset of the Big Bang, all the matter of the universe existed as a singularity that was infinitely dense and it, suddenly, expanded several times the speed of light. Once the expansion, or explosion, occurred the mass was no longer homogenous, but was clumped together, which can explain the formation of the planets, stars, etc. It's funny that all the big brains of the scientific community can tell you what happened .1, .01, .001 seconds (and so on) after the big bang, but none of them can tell you what occured the half second before.

For your theory to work some 'thing' must exist before the Big Bang event and in which it could occur. Science has found absolutely no evidence whatsoever that any 'thing' preceded 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 didn't happen in a place.  Space and time were created in the big bang. The Big Bang is a theory to explain universal/spatial expansion. \n\nI think it's easiest to look at the idea this way. Scientists have observed that everything past our local galactic cluster seems to be retreating from us. All observations point to the universe being infinite and roughly uniform in all directions. \n\nIf it's expanding at given rate now, chances are it's slowed down. Go back in time, the universe was denser and expanding faster. Rewind the timeline far enough and you'll come to a period when everything was all bunched together in a massive, undiscernable clump. Then, suddenly, Bang!!! Space! And everything in it... which has been spreading out and slowing down (pretty much) ever since. \n\nTry thinking about it like the air expaning in bread as it rises, or in a balloon as it fills. Everything is moving apart from everything. Only the universe has been infinitely large from the get go. It's almost like someone just keeps adding empty space in between everything.\n\nIf it helps at all, the center of the big bang for the visible universe was the same place the center of the visible universe always is. Wherever you are. From that point, everything you can see was at some moment in the past gethered together in a lump with infinite density.

The total amount of energy/matter (they are one in the same) in the universe now is exactly the same as it was an instant after the Big Bang.  As for where the Big Bang came from, I think you have to be a deity to know that one.

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.

Black holes are very dense spaces where eveything is sucked up. It cannot be the cause of a big bang because the bang cant occur in the first place. Even if there was a bang, that would be sucked up too.

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!
