The Hawkins model of Time-Space will start to engender an idea of the concept. Hawkins basically ascribed time-space to be a moment by moment point along a continuum, with time and space fanning out in a infinitesimally increasing cone ahead and behind the momentary point.
Given our position at that moment of the time-space contnuum, and ignoring the phyics of reversing time-space, we can only see what is BEHIND us. In essence, time travel, as everything we see/perceive has already happened, as we are at that point on the continuum, and we cannot perceive/see the future (your actual 180° when you take it into proper perspective). YET. We may at some point, but to be able to isolate a human being - either corporeal or atomic level - from the space-time continuum is impossible. Technically - IF - we could travel through time, it stands to reason that without a way to isolate the human from the STC, we could only travel BACK in time to the point of our birth, and realistically, we could only REMEMBER back to the point at which we had made the conscious decision to travel back in time, for once we pass that moment, we have forgotten what we were doing... hence, why it is an enigma within an enigma... the great space-time CONTINUUM.
That is a simplistic view of time-space, but it works well enough.
Then we factor in Einsteins general theory of relativity - E=mc˛ (assuming c - speed of light - is constant, as is currently believed, at 299792.5 km/s). Square the speed of light, factor in human mass, and behold the energy (E) required.... kinda large!So, for a given amount of Energy, and upholding that c is constant in a vacuum, you can see that MASS becomes an issue
AH, I could go on, but maybe should not.
