The Big Bang Theory
by Nicole Chin & Jamil Gittens
Our universe began about 5 billion years ago. It exploded out of nothing in an event called the big bang.In the begining the universe was hot and packed into a place smaller than an atomic nucleus.
The universe is thought to have inflated and particles of matter were created from the size of an atom, to the size of the earth. A dense mixture of radient energy and exotic particles such as quarts. The expansion of the universe continued at a steady rate, though the temperature continued to fall. As the temperature continued to fall annialation overtook particle creations and the universe became dominated by radient energy and lighter particles (such as electrons). These electrons and similar particles were mostly annialated in a period of 3 minutes. While this was occuring a quater of the protons and atoms combined and made helium nuclear.
For the next 300,00 years very little happened, the universe continued to expand and the temperature dropped. When the temperature finally dropped to 3,000 degrees kelvin,the electrons began orbting protons and helium nuclear atoms,without them being torn apart by heat. At that point in time,the begining structure of the universe appeared with huge ripples and lots of radiation.
