>>14328598Time is not simultaneous. The main reason it won't work - and this is the unfortunate critical downfall of all FTL theories - is because the past is not a real physical thing that exists. Time is not simultaneous. To go to the past you'd actually have to go there, but there's nowhere to go. The past doesn't just sit around and wait for us; time is not simultaneous. The implication of time being simultaneous is that, from the perspective of the pastians, the future already exists. This means you are working with a fully deterministic universe. And any interaction the future has with the past would logically also be a part of time, because 'time is simultaneous', which means any time travel is automatically a paradox because going to the past and changing things implies changing things, which is at odds with the deterministic universe you have created.
Every time travel story in the history of man, or at least every one that I've seen, has ignored this principle by ignoring the fact that time is (allegedly) simultaneous. They do this by hoping you will not notice the misdirection. My recommendation to you is do whatever you want, but do not claim that it is based on or even anywhere near to real science because by doing so you are perpetuating an EXTREMELY aggravating myth/plothole that appears in almost every science fiction story that incorporates time travel.
