While I lay here wishing I could fall asleep I found myself thinking about the Minions movie. If you’ll recall the scene at the villains fair you may remember the part where a scientist kept grabbing future versions of himself to help him in the present, which then led to the original version accidentally being killed and all future ones disappearing. And that got me thinking. Let’s say I have a bowl of soup, and I want to go to the future in order to bring back the future soup so I can then have 2 bowls of soup. The problem is eventually I’m going to eat the soup and then there’s no more soup. So if I go too far into the future then there will be no soup, but if I get it too close to the present then I’ll just have a constantly disappearing bowl of soup that keeps getting snatched up in the past. But mostly the problem is the soup is going to get eaten, and so if, let’s say I have a viewing glass that let’s me see into the future, would I even be able to see said soup because the only possible future that exists for it is that it’ll be eaten. Even if I decided I wouldn’t eat it until I brought a future version of it back the future would still show it gone.
Because isn’t traveling to the future in a way like traveling to the past. I mean of course we’ve all heard of the butterfly effect. Step on a butterfly you alter the future. So any events we might experience in the future or things we may bring back from the future would alter our present self which would change the future’s past that had been the time-line that led to the future we experienced that would no longer exist to be there for us to go to to alter our present.
Besides even the butterfly effect for our past doesn’t really make sense. It’s like the movie The Time Machine. In it the man builds a time machine to go into the past to save his fiancé, but while he’s able to alter the past in where she dies or how she dies, the fact is she always dies the same night, because if she never died he would’ve never built the machine to go back to save her. In other words we can’t change the past in such a way that would’ve kept us from going back in time to begin with. So no matter whichever direction you travel in you would create a paradox that would prevent all reasons for your travel or keep you from traveling to begin with.
In fact the only way I can see time travel existing is if it’s already a part of our time-line. As in we travel in time to cause events that already happened. Kind of like the movie Deja Vu, where the ending may have varied but it took the time travel bits to create both outcomes to begin with. Or more simply, like The Terminator, because if the robots hadn’t sent a Terminator to the past to kill Sarah Connor the humans wouldn’t have sent Kyle Reese to the past to protect her, and they wouldn’t have hooked up to create John Connor, the whole reason the robots were after Sarah.
And these are the thoughts that keep me up at night.
