Well yeah i was curious to see if others came to this conclusion so let me ask another thing. Since the world is how we know it, unless directly involved, can we even tell that these types of things haven't happened or isn't possible of happening?
Let's say i'm John Smith in 2011, and i say to myself. If there is ever time travel and i can come back in time and leave myself a note before i get to work today, and that note never shows up on your desk at work, that I John smith never created time travel?
And lets make that question more broad by saying, If anyone promised themself they would come back in time and never do, that time travel is never created? Or is absent of this question entirely because the two instances are not parallel?
again
traveling backwards in time involves paradoxes. in the case where you travel backwards to a time that you weren't a part of, you can explain those paradoxes away using two separate realities. in this case, i can't even imagine how it could plausibly work. how can you exist twice simultaneously? how could you have two separate perspectives?
i mean, even in the first case where john smith changed a war...you run into all sorts of problems. once john smith changed that significant event, does the new course of history involve john smith's birth? if not, how could he have traveled backwards to change anything?
this is why these hypothetical situations are ridiculous. you can't really approach them from any rational standpoint because they don't abide by general rules of consistency within logic. they're entire paradoxical
