I've found my explanation of the Big Bang theory. It's a little over-simplified, but it covers all of the main points:
The Universe originated as one point, almost infinately small. Something [God, maybe? We don't know for sure.] caused it to expand. In it was lots of pure energy. This began to form into particles [Quarks, Leptons, WIMPs, and various others], through that thing Einstien thought of. At first, they were formed as Particle-Antiparticle pairs, so they instantly annihilated[sp] to repay the energy used to create them.
Then, after less than a thousandth of a second, the universe expanded hugely. The huge gaps created pulled the Particle-Antiparticle pairs apart, so they had no need to annihilate[sp]. Free to go their own way, the Quarks began to form into Baryons, such as Protons and Neutrons, and the heavier Leptons broke down, leving only light Leptons such as Electrons and Neutrinos.
At first there was one Unified Force, which emcompassed Gravity, Electromagnetism [Light], the Weak Force and the Strong Force. As a result of Expansion, however, the force was split. From that point on, Gravity was carried by Gravitons, Electromagnetism by Photons, the Weak Force [which later caused the Nuclear Fusion in Stars] by Weakons, and the Strong Force [which late held Protons and Neutrons together in the nuclei of atoms] by Gluons.
One thing that puzzled scientists for a long time was why the universe today is composed of matter, when matter and antimatter were created in equal amounts. We now know, however, that the X-Bosun decays to form more Matter than Antimatter, which is why there is so little Antimatter left.
The Protons, Neutrons, and Electrons began to form into atoms, due to gravitational forces and magnetic attraction. The Neutrinos and WIMPs remained in the background, as Dark Matter. Most of the atoms wer Hydrogen, with some Helium and Lithium.
Because of Gravity, the Hydrogen began to clump together, into huge balls of hydrogen, which became very hot, and began to fuse the Hydrogen and Helium to make heavier atoms, releasing a lot of Heat and Light at the same time.
I think I can also shed some light on the origin of life on Earth as well. I'm not an expert on this either, but I think I know roughly.
Basically, as a result of Nuclear Fusion in stars, there were now lots of elements around. Six of these were Hydrogen, Carbon, Oxygen, Nitrogen, Sulphur, and Phosphorus. The Earth at that time was very stormy, and so it was only a matter of time before lightning struck a small concentration of these elements. This isn't particularly probable, but if you consider the size of the Earth, it probably happened several million times around the world. Where it did, the elements began to combine into compounds, having been given the energy to. Eventually, a Compound called Deoxiribosenucleic Acid was produced. This molecule is self-replecating, and produced a lot of proteins as a side product. The gradually coalesced[sp] into small amoeba-type organisms, and then Evolution did the rest.
I cannot be bothered to explain Evolution this late at night, but I'm sure someone will be able to fill you in. I'm not too sure of the facts of the bit about the DNA, so if anyone knows it in a bit more detail, could they tell us, please?
