  1. A short history of nearly everything Bill Bryson Chapter 1

  2. Sample on how we began

  3. Singularity

  4. What it takes to make a universe • 1st second: gravity and other forces that govern physics • Less than a minute: the universe is a million billion miles long • 10 billion degrees of heat (nuclear reaction) • In 3 min: 98% has been produced

  5. The Big Bang • There have been many arguments on when creation began • They believe it began 13.7 billion years • Around since 1920’s • Didn’t become active until mid 1960’s • Two radio astronomers • Panzias and Wilson

  6. Panzias and Wilson • Trying to use a large communication tower • Too much background noise • Noise came year round • Tried to find the cause by testing every electrical system • At the same time • Princeton found that if you look far into space you can find cosmic radiation left over from the big bang. • Found the edge 90 billion trillion miles away

  7. What caused the Big Bang • Relic of an earlier collapsing universe (cycle) • False Vacuum • Big Bang is about what happened after the bang • They believe they can go back as far 10 -43 of a second after the creation

  8. What happens if our universe is altered?

  9. What would happen if you traveled out to the edge of the universe • You can never get to the end • If you kept going you would end up where you began • Universe bends • Allows to be boundless but finite • Space is not expanding but galaxies are rushing apart • We don’t know where the center is

  10. For us the universe goes on as far as light has traveled in billions of years since the universe is formed • There is more space then you can imagine
