In school we are talking about the big bang, and it made me think. What if the cause of the bang was from a group of galaxies before us, very similar to us, and it was expanding just like our, but then we hit a "border", which caused a reverse action. Making that universe compact together and get so tight that it created a very large expansion, which we call the big bang theory.
