Plus I really identify with a idealistic person seeking to change history itself to create a better future.
Oooh, I like the sound of that potential plot direction.
There has been mention in various Star Trek media where time travel is featured of a Temporal Prime Directive, which is the same non-interference policy, except it basically states to not interfere in the past, in any way, shape, or form.This idea might also touch on Starfleet's General Order 1 (the prime directive), which prohibit Starfleet members from interfering with the natural development of alien civilisations, protecting unprepared civilisations from the danger of starship crews introducing advanced technology, knowledge, and values before they are ready to understand and use them properly. One reason for such a rule pertaining to time travel might be to avoid, as far as possible, the bootstrap paradox, to ensure that technology was developed when it was supposed to. Just imagine the impact a simple (again to us) bic lighter might have if presented to someone living before the invention of matches. Would it change the course of technological evolution, and if so, in what way?
