Big Bang Model

 

Everyone in the public thinks that the big bang model is just when the earth started out as a single point and had an explosion. When in relatity it wasnt an expostion and thats whats wrong with it. it never has been because of an explostion just people always thought that so now thats what people think it is. It is accualy streaching of space and how everything is moving away from each other. There are people who think that this never happpend, when it has happend the past 15 billion years. One thing that they have is the inflationary theory and that says that the universe began hot and dense. The ekpyrotic proposal is saying that the univers was created because two three-dimensianal worlds came together to form one and said that it ended up being a flat universe.
