PPT-The Big Bang Theory

Time begins The universe begins 137 Billion years ago The universe begins as the size of a single atom The universe began as a violent expansion All matter and space were created from a single point of pure energy .

In this session we will continue our examination of the Big Bang theory . and looking at problems associated . with the model. Keep in mind, we can only cover a portion of the material out there! There is always more that you can study on this topic. Darci. Collins. Beginning of the Universe. In Medieval philosophy there was much debate over whether the universe had a finite or infinite past . Johannes . Kepler. used the dark night sky to argue for a finite universe..

The Universe. The big bang theory. Happened approximately 13.5 billion years ago. The Big Bang was caused by the density of the compressed galaxies. It was in a very high density state, then it expanded. After the beginning expansion, it cool to let subatomic particles and later on, simple atoms to form. .
