WHAT IS THE BIG BANG THEORY?
The big bang theory is a theory about how the universe became in the beginning of time. People say this may have happened 14-15 billion years ago. Some believe a universe came to be by a gigantic explosion.
Order of Steps
1. Cosmos go through an "explosion" expands from size of an atom to that of a grapefruit in a fraction of a second.
Time-10(-43)
2. Post explosion, universe full of newly formed electrons, quarks, and other particles.
Time- 10(-32) sec
Temperature- 10(27) celecius
3. Cosmos cool. That allows formation of protons and neutrons.
Time- 10(-6) seconds
Temperature- 10(13) celcius
4. Still too hot to form atoms, charge electrons and protons. Prevent light from shining: Universe super hot fog.
Time- 3 minutes
Temperature- 10 Fahrenheit
5. Formation of atoms:
Mostly Hydrogen; helium. Light can finally shine through.
Time- 3,000,000 years
Temperature- 10,000 celcius
Time-10(-43)
