wolfgang Posted July 16, 2016 Report Share Posted July 16, 2016 The Big Bang theory is the prevailing cosmological model for the universe from the erliest known periods through its subsequent large-scale evolution.The model accounts for the fact that the universe expanded from a very high density and high temperature state Some estimates place this moment at approximately 13.8 billion years ago, which is thus considered the (age of the universe) After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies. My question was so: what if the whole universe was inside a colsed room? and the galaxies were just like dust particles hanging there , if these paricles are subjected to a continuous diverging gravity ,so they will expand. That means , that there was NO start point and NO Big bang theory ! What do you think? Quote Link to comment Share on other sites More sharing options...
