TL;DR: the concept of time itself is a very human ideology that might not even apply to the universe, thus making chronokinesis an extremely abstract ability similar to umbrakinesis, in fact, even more abstract to a point where it just would not work.
Wow, I haven’t written one of these essays in a hot minute, but anyways here we go. The topic of this essay is about a very popular superpower in the media, time manipulation. The ability to fast forward, rewind, travel to the past or future, even stop time itself is a very common concept explored by countless amounts of stories and many notable characters/objects come into mind when thinking about it: the Delorean, Dio brando, even the flash to an extent. The idea of time however, is rather artificial, and I’ve come to talk about if time even exists as a tangible thing in the universe, or just humans making an abstract concept and giving it a name.
According to Albert Einstein and many other physicists, time is not real. Well, it’s not something that exists objectively. It’s not a fundamental. So this means that chronokinesis as a whole is based on a very human and very hypothetical concept that describes the way things happen in the universe.
This also implies that things such as the past and the future wouldn’t exist either. The universe is in a state of constant change. Some physicists say you would need to travel infinitely fast to go to the past, but that’s obviously impossible and chronokinesis users aren’t normally “fast”. (well, the flash is, but he is such a ridiculously bullshit character that I’ll make an essay on superspeed another time). So this means that things like the delorean and the police box could not possibly actually work.
Now what is chronokinesis actually controlling? I’m not sure, unlike umbrakinesis in which I had some possible theory that matched the profile of it well, chronokinesis is a very, very abstract concept, perhaps too abstract for me to even give it a plausible explanation. Now this doesn’t mean the idea of the power is bad per say, there’s many “hypothetical” concept powers out there, like spirit manipulation, demon/angel mimicry, etc etc, but I guess chronokinesis is one of those things that can only exist because of the rules that the universe it works in sets for it, and in general, would sadly be impossible.
