1. If we make graph in which big bang is on x axis and time is on y axis then at the time when big bang took place it will origin and as time is independent quantity therefore it would be constant and after big bang universe was formed. It is expanding day by day but the time will come when it will be contraction will took place therefore once again the space will be contracted into a small dot and again big bang will take place and thus universe will again.It can be true?
2. Also if we can able to move out from this dot like structure then we will be able to travel with time and we will be able to decide the future of our self. As now we are inside space there for we are following spacetime and if we move outside the space then we will be able to travel time and we will be able to control our time. It can be true?
