Many mysteries surround the concept of time travel. Is it possible? What would happen if we had the ability to travel to the past or future? Will it take the meaning of life to a different level? There are controversies from mathematical, astronomical, and philosophical regions of thought, and so I would like to digress my own thoughts to myself on this computer.
Can one truly travel through time without being affected by time him/her/itself? The idea that no particle or once-thought thought would be unthought with the passage of backwards time, erasing what had already been. And would it matter if we went back through time if everything that had been thought and had been was unthought and unbeen, then everything at the point of time in the past that thing stopped at would all be the exact same. No memory of the future would be present in the past, no particle that was once a part of the body would exist, or in an argument of existing particles, would exist as a part of that body. Thus the ability to travel backwards in time would be of no consequence. If man did truly find a way to go back in time, it would only keep repeating itself with no molecular slight as an old record player stuck on one line repeatedly. There would be nothing we could do, for not only would we not know it had already happened, but in not knowing, do it over again.
It has been brought to my attention that if man had the capability to fold space and thus time, then we could travel unharmed by the affects of time. Space itself has already shown this is capable with black holes, if the theory of the black hole is correct. But there is little possibility man will be able to create such a force, to be able to fit so much nothingness into a pinpoint, possibly sending it back to the beginning, thus the cycle of the universe never ends…
Even if you were able to separate space form itself putting a controlled time environment on a different level as reality as we know it, allowing only a certain fragment of space to 'travel' backwards instead of following its natural course, in what manner would this shape be made? And, if it is able to be formed, how would one continue the normal movement of time within such a selected space without altering it? For example, if one were to successfully separate a section of space, how would it be able to keep the normal flow of time continuum, thus retaining any knowledge hitherto gathered by passing through time and, supposedly, back again?
Another problem with this theory then is, what fills this transformed space once it starts its journey? Is it to be thought that it will exist twofold, in either time at the same time? If one would take into account the philosophical materialists' theory of existence, this being that everything has always been in existence with nothing new coming into existence, but instead matter is just being rearranged in a different order, how would one be able to alter the amount of matter in one time to increase the amount of matter in existence at a separate point in time? One would have to 'create' new matter, which has existed at one time, but in removing it (something which, as far as we know, has never been done) place it as 'new' matter in that space while taking existing matter out of the original time to change the amount of existing matter in that reality.
