Time travel is impossible now at our technological level, but whos to say in the future it is possible?
Time travel is difficult to explain, some people think that time travel ISN'T possible , you only travel between alternate worlds at various time
frames, seeing as apparently there are infinite dimensions therefore infinate possibilites, How ever if Time travel was possible like everyone assumes
Time travel to be , i.e starting with a time machine and actually traveling back or forward in time on your dimension then if would be very difficult
to not interferre.
If you could travel back to a period of time in your ( our ) worlds history , any intereaction between you and the past would have effects on your
time, like the 'Grandfather' effect or more commonly know as the 'Butterfly effect' , like going back to prehistoric times and stepping on a
butterfly therefore a minor event in the butterflies period but could have devastating knock on effects in yours, like going back in time , meeting
your grandfather as a child and accidently killing him ( before he had kids) , how could you be born to travel back in time to kill your grandfather?
If you wanted to learn about the past firsthand like going back to Pompei the night of the eruption you would either have to observe from quite a way
out or if you wanted to get right into the town you'd have to be totally inconspicuous, learning Latin, dressing and looking like a native, with
little or no interaction in speaking to the natives or warning them of the events to come.
If you so much as mentioned the eruption someone who should have died as a result of the blast, ran and lived , what through the course of THEIR
actions ( which wouldn't have been possible because they were supposed to have died) would the world of yours be like?
Its like I thought recently all the people that have died in the recent wars , what actions would they have done and how would it change the future,
for example, a child killed in a US air strike could have created the cure to AIDS or a free energy generator.
Possiblities abound but with Time travel you'd have to be very careful, I'd favour the seeing from afar , like historic UFO sightings, were they
futuristic sightseers? at least history records them as unknowns , at least that wouldn't have a tremendous impact on the future, they would become
folklore but direct contact would and could destroy the world or at least the future/your present as you know it.
