the concept of time travel fucks me up. if time travel became possible and you could go backwards or forwards in time, then you could potentially open up the concept of time travel to all periods of history. if time travel is EVER invented, then we would know by now because it would happen in the future, but they could still visit us. how would that work? imagine you go to colonial america 1678 and you pull up in the woods with your time machine from 2235 and some hester prynne type woman is like, shit, you’re from the future? get me the hell out of here. so assuming everyone from the time period in which time travel was invented KNOWS about time travel, so do the people from that point onward. so how do they integrate that into society excluding history before that? how do they measure time if everyone is separated by time from traveling through different periods? how do you measure age? how do people even age? if your time traveling buddy came to hang out with you in 2456 but he died, could you not just go back to before he died and hang out with him then? and back to the colonial thing: assuming time travel is opened to the rest of human history, how would that work? surely future tourists would go back into the renaissance era and be like, yo, what’s up, this is my apple computer. and these people who have been shitting in buckets for all their lives would be like, hell no i’m not walking 5 miles to the renaissance grocery store anymore, i’m getting a mercedes. so they go to the future to learn how to drive, then bring back their car, and suddenly antonio’s wildin in the streets of venice in his big metal machine and everyone’s like holy fuck, what else do you guys have? and then renaissance motherfuckers start opting for more convenient and helpful future technology, and suddenly the renaissance isn’t renaissance no more, and cavemen are hooting and screaming playing fortnite together in the stone age lounge because it sure beats throwing rocks against the wall all day until you get eaten by a sabertooth tiger at the ripe old age of 23. so people would probably be spread out evenly over the eras just chilling with whatever technology they fuckin want, but that would mean that history would all be blending together, but wouldn’t that also mean that it already happened? the world started and romulus and remus had an xbox and king tut was texting when he got ran over by that carriage. there is no past, it’s all just one big fluid series of events with every human that has ever existed all existing together. would it even be possible to go back to a time where people hadn’t gone back in time? to go back to the time before george washington ate a big mac?? before atilla the hun had a meme page with 30k followers? it’s all too complicated for me. so we’d assume that time travel would be kept secret from the past, but we still run into a similar problem from the time that time travel is invented to the eventual demise of humanity. if a meteor crashed into the earth and killed everybody in the year 3071, we could just keep going back in time to avoid it, but eventually we’d have so many people crammed into that ~900 year period that it would fuck up everything. but you could also go back to the time where things weren’t overpopulated. just keep going back and back and back. or you could send small groups of people and families to live undercover in different historical periods so they escape the overpopulation of the future, but they don’t reveal time travel to the past and fuck up the whole thing. this shit is so wack i don’t understand how they wrote doctor whom or anything with time travel. good fucking yard.
