On the Feasibility of Time Travel and Its Implications

Time travel has been demonstrated to be feasible, at least in theory. This raises issues dealing with our awareness of time, the problem of a frozen history versus free will and the existence of time paradoxes. A different understanding of time suggests interesting possibilities. Time periods may coexist and the past may be as indeterminate and variable as the future. Changing the past, in fact, cannot change the present and our limited perception of only the here and now may have helped our survival as a species. Even if the universe were to come to an end, there is a way for the human race to remain immortal.
