THE BIG BANG THEORY
- 1. THE BIG BANG THEORY Patricia C. Persia 11-Albert Einstein
- 2. The Big Bang theory The idea that the Universe was suddenly born and is not infinite.
- 3. This idea was made when Albert Einstein gave us a better understanding about gravity using the Theory of Relativity
- 4. And Edward Hubble discovered that the galaxies are moving apart from one another.
- 5. But what really happened in the Big Bang theory? Was there really a large explosion?
- 6. NO! There was no explosion, rather there was an expansion!
- 7. Approximately 13.8 billion years ago there was an expansion, and from that expansion all things came to be.
- 8. So this is what really happened
- 9. 1ST The cosmos goes through a superfast “inflation” expanding from the size of an atom to that of a grapefruit in a tiny fraction of a second.
- 10. 2ND Post-inflation, the Universe is a seething, hot soup of electrons, quarks and other particles.
- 11. 3RD A rapidly cooling cosmos permits quarks to clump into protons and neutrons.
- 12. 4TH Still too hot to form into atoms, charged electrons and protons prevent light from shining: the universe is a superhot fog.
- 13. 5TH Electrons combine with protons and neutrons to form atoms, mostly hydrogen and helium. Light can finally shine
- 14. 6TH Gravity makes hydrogen and helium gas coalesce to form the giant clouds that will become galaxies; smaller clumps of gas collapse to form the first stars.
- 15. 7TH As galaxies cluster together under gravity, the first stars die and spew heavy elements into space; those will eventually turn into new stars and planets.
- 16. The Universe has no borders it still continues to expand and expand from all around it is just nothing.
- 18. But there are still many questions on how the Big Bang started. And maybe we will never be able to answer them. But one thing is for sure.
- 19. It is that everything as we know it started from it and we will just have to keep exploring.
- 20. Remember, that we are part of the Universe therefore we can say that we maybe the Universe’s way of experiencing it. So let us keep exploring and experiencing until there are no more questions to ask.
