RE: Time travil.. This is always going to be an extremely interesting topic with many ideas and theories.
One theory i've heard was that Time is defined by light. Therefore the star you afore mentioned is indeed showing us the past since it takes many many years for the light to reach us. Therefore if we could travel faster than the speed of light, back along the light waves from the star that exploded, then at a point revert to the normal speed, we effectively would have traveled into the past and continue with time at that interval. (bloody confusing i know)
Another theory is that there is no measure for time. That we live both past, present and future all within a single instance. Our lives are thus layered with an infinite number of parallel multiverses. Which means if we could jump to a previous point in our life, we would not actually meet ourselves or cause any catastrophic event, we would simply select another branch from our infinite vault of random outcomes. (not to be mistaken with chaos theory - eg'Butterfly effect'...thats a whole other theory)
I like to believe that the parallel theory is correct as it explains many bizzare or unanswered life events such as de ja vu, astral body travel, psychic phenomenom...etc. though i doubt anywone in our life time or if ever will develop a means to physcally jump to another plane. Quantum physics would be the closest logical analogy with regards to this or time travel. and that in itself is Extremely hard to grasp. |
