Ok, this is more a stream of thoughts than an actual question but...I would love to be able to travel back in time to when I was a teenager. These were some of the happiest times of my life and I have a lot of nostalgia and think about these years often. However, when one thinks about time travel, it poses so many more questions than just the practicalities of actually going back in time because what I am really seeking is to live an earlier experience all over again as a novel experience, however, if one were to be able to do this, then they would not know they traveled back in time as they would have no memories of experience of the passing of years.
So the conundrum is, that time travel (in my case to the past) is desired because I would like to a) experience my youth all over again but b) make changes, however, it is impossible to do b) without knowledge of the present. You cannot experience both the innocence and wonder of an original experience as if it were the first time but also have the necessary memories from your future self to be able to change your destiny.
Also, from the physical aspect - if you travel back in time, does your consciousness move to a younger physical self or is time travel literally physical transportation of your current physical self into a earlier setting in which everyone and everything around you is in the past? In which case, where is the younger "you"? Surely, therefore, time travel to the past could actually be done via consciousness/manipulation of reality (if you believe time is a field and not a forward moving path as Einstein did) rather than moving physical particles (your current self) through space (which is what most time travel theories focus on).
