Sometimes I wonder….. Is time machine really useful? If time rewinds I will go back in time. But if I don’t remember present me, I will again live in same way like how I lived last time and it will be just a repetition of same thing. Against many people fantasy, rewinding time is waste of use until and unless we carry same mind to past. This mind is product of all experiences which will teach it and suggest corrections in past. So, its not possible to carry todays brain and to have it in past where there are no experiences.
Then there is other question. Is it possible to have future mind today with out experiencing or atleast without loosing something? That is nothing but the simulation. That means, simulating capacity is more previous than rewinding power!!! Rewinding is a fantasy.. Simulation is not….its 100% perfectionism of future planning!!!
