    there are many theories regarding the origin of the universe. one of the most popular is called the big bang theory (how appropriate.. considering that it's the start of the new year) :p

    basically, that theory states that at some (indeterminable) point in time, a very very dense ball of energy exploded.. thereby causing the universe to be (continually) created.

    First of all...Swede, take the God thing and go to the Religion section. You will be more excited with the questions and answers there.

    Beginning of the Universe? I have seen this question, and questions about how big the universe is "thousands of times" on this site. It seems that no one ever looks at a search on their browser before asking.

    Some theories say that the universe begain as a huge explosion (big bang theory), and what we see now is collections of debris from that explosion circling around other collected debris, and expanding outward from the original point of the explosion. The explosion occurred more than 14 billion years ago, so we will never know how, or what really happened. Other than some folks constantly asking the question, it is rather immaterial because you cannot go back in time to verify or disprove the theory. What you can do is to carefully observe the way things exist in the present apparent harmony with one another and create theories about how that came to be. Since some really vast distances are involved, and objects in space vary from grains of sand (or ice) to gigantic masses of gas and metallic rock there is no simple explanation that will satisfy all the people.

    I recommend that you read ASTRONOMY by Ian Ridpath, DK Publishing, NY,NY. Ian presents what is probably the most reasonable answer to your question. It is to lengthy to retype here. Note that the Big Bang theory does not attempt to explain what came before the explosion some 14 billion years ago...no one knows. The Big Bang theory was developed by a Russian born physicist named George Gamow with assistance from his colleagues in the 1950s. His hypothesis, as related by Ian in his book, suggests the sudden expansion of the universe from a small point somewhere, very very rapidly into an immense geographical area measuring some 100 million light years in diameter. That is essentially what we have today, but the process is still going on, so the total size is really unknown.

    The entire theory is pretty well thought out and involves some deep level math to follow along with. Since I cannot fathom some of that math, I am forced to agree with the theory by default. After all, I don't have a more reasonable one to replace "Big Bang".

    No one knows how it BEGAN, many people think this is explained by the "big bang" theory, however this only describes the evolution of the universe. What we do know is that about a billionth of a nanosecond after the universe began it was the size of a marble and extremely hot and therefore volatile. As it expanded rapidly, stars formed and elements also formed. Some stars collapsed in on themselves and this created planets and other elements. The universe is still expanding now.

    The beginning of the universe can refer to either:

    Big Bang, the scientific theory that describes the origin and evolution of the physical universe.

    Other Theories. Non-standard cosmology

    Various non-scientific origin beliefs about how the universe started.

    Cosmogonical speculations of the origin of existence and reality.

    According to the Big Bang, the universe emerged from an extremely dense and hot state (bottom). Since then, space itself has expanded with the passage of time, carrying the galaxies with it.

    From a seperated black hole. A black hole seperates from another universe and the very moment it seperates it blows up(big bang) because there would be nothing to hold it together.

    So all the matter that was collected from the black hole would now be matter in the new universe. The universe before ours would be MUCH more bigger than ours and the universe after our would be much much smaller. But to the people in the universes it would seem the same size.

    A human in the universe after ours could be the size of mountains or planets and the universe before ours their 'humans' would be the size of our planets.

    Knock your socks off and read this... Hell, I am just reading it for the first time too. :)

    Im still foggy on the whole idea of the universe..I mean I dont understand a place starting from a place where there was no place.. I am completely in the dark "pardon the pun" but it sounds a little squirley to me.. the whole concept of the creation theory .You have to be in a place to create a place doesn t that stand to reason?

    At the moment of the "Big Bang" some 15 billion years ago.

    According to string theory there was a collision between two parallel BRANES which provoked the big bang

    It may begin by Big BANG.

    After second explosion
