Answer 2

The Big Bang Theory is the dominant scientific theory about the origin of the universe (I believe one of the other answers summed up the religious viewpoint by referring to that act as the creation of some deity referred to by believers as God but whose own existence they can not explain - simply replacing one unknown but possibly understandable event with another that is in the realm of the supernatural). According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that tossed matter out in all directions. It is of course a little more complicated than that and I refer you to the sources. There have been and still are alternatives to this theory and some of the sources talk about these. Sorry for the sort of long list but there is a lot of talk about it.

Answer 3

everything in the universe and the universe itself started with a small ball of pure energy smaller than a grain of sand around 14 million years ago. there was nothing around the ball, and nothing came before it, it was such a large explosion it created space and time. so before it, there was nothing. a few seconds after it exploded the energy began to cool down and form quarks in a period called quark soup. quarks formed protons (electrons are single molecules, called leptons, so they were formed right away too im sure) and the protons and electrons formed hydrogen atoms. hydrogen atoms were pulled together by gravity and formed stars, 4 hydrogen atoms collide (2 hydrogen create 2 neutrons, and 2 more hydrogen supply 2 protons and 2 electrons) in stars to form helium. helium forms carbon and oxygen, those form neon and magnesium, and that continues to iron. heavier elements like uranium im not so sure about, they might have been created in supernovas (exploding stars).

that takes u from the start of time, to the creation of the elements.

Answer 4

Go to www.pbs.com and look for the 'Origins' series, which is being aired again now, on Tuesday nights. The Big Bang was covered just tonight--wow!

Answer 5

There was an infinite and absolute void. For some reason that's totally unknown, a mathematical point in that void (..called a 'singularity'..) suddenly changed into spacetime and energy. The spacetime began to expand and cool while the energy gradually created matter.

Answer 6

come on a punk i telling u wat it is that means his teacher was hot =)


well ok they think that evry thing in the univers was together at one point all the stars and planets were one big mass , so the theory is that that mass exploted and thats why everything is still moving apart frm each other
