A paradox of time travel, more like an issue, is this concept of the butterfly effect. Even the most minuscule of actions could seriously alter the future in some way and we could never be sure of the effect.
Movies, shows, books, comics… this hypothetical situation plays out everywhere. While it makes for fun musings, I want to consider another adjacent idea.
Suppose this is true and any alterations to the past, no matter how minor, have serious consequences. Well, then what do our current actions do for the future?
Eventually we will get to a future that extends from our actions at some point, so what actions are you committing today? If even the smallest gesture or act can alter the world of tomorrow in a big way, wouldn’t it be wise to do as many good actions as possible?
Or maybe you don’t have to concern yourself with the grand displays and focus on what’s in front of you, knowing it does have a big impact in the grand scheme of things. To be honest, it’s probably the only thing we can handle right now anyway.
