I was wondering what I was going to blog about today, but as I was brushing my teeth, it came to me. Basically, a subject I've always wanted to talk about. It's part of my beliefs, you know, kind-of the thing on meism I talked about before, a huge portion of it in fact.
I've talked a bit about the multiverse and its ties to fate/destiny and how that ties to my conceptualization of God, but there's something else the multiverse ties to. This ramble will also involve a little popular culture here and there, from Space Dandy to Dimension W to others.
Basically, I wanted to talk about the relation to time between people and it. There are an infinite number of universes because in every split second, there are an infinite number of ways that interactions can happen. On a higher level, many of these universes are very much the same, with only the slightest fraction of a difference. Yet they continue to expand, with time, infinitely diverging.
Time is also directly tied to space (we know this), with perception of time being subjective rather than objective. I forget the science behind that, but I believe that's true, so you can say, in a sense, our observation of time is what makes that time true. (Or, the observation of the possibility makes the possibility true.)
My basic belief, there, then, is essentially that the number of universes we can be in is always different. We're different people from every second to the next, because of the split off in thought, in observation, in action. Most of these different people maintain near-identical universes, so we could easily swap between them and never know the difference. A single particle's difference between one universe and the next would not, after all, be noticed.
So, that's where time travel comes in. It's physically impossible for us to do, but assuming it wasn't, assuming that the theoretical ability to time travel (which we already know about) was made less theoretical and was actually possible, or some other form of time travel was deemed possible...I think it would work along those lines.
Meaning, that by going back in time, you're automatically going to come back to a different timeline no matter what. This does not, however, make your changes meaningless. The changes you make in the past will still have meaning. There's an infinite number of universes, but while there's an infinite number for each possible moment, the universe you find yourself in is following a similar path to many, many, MANY other universes, all "close" to your own. Think of it like an ever-expanding treebranch. Your universe is one branch, that splits off into many more branches, with every passing second.
So by going back to an earlier branch, you're making changes that will lead to many more branches being created, by your new observations. The old branches still exist, but the new branches are born because of your actions, be it good, bad, or neutral. So, basically, what this means is, at least on some level, the truth is in your perception of your world. All actions exist in some universe. You get to choose, through both your own thoughts and what you see, what actions happen in YOUR, the very you you are in the very second, universe.
Because the more consciously you think in a certain way, and the more you choose to see certain things, the more universes which feel like you are close to you.
In short: everything is both real, and not real, and as a result, everything you do is both meaningful and meaningless. There will always be a you who decided to act differently. There will always be a you who thought differently. There will always be a you, who did something you think you could never do, so in that sense, they are not you anymore.
But I believe all these selves are still, on some fundamental level, linked: the tree is ever-growing, but has the same roots when you go far back enough. Consequentially, living life to the fullest extent possible while trying to help others live life to the fullest extent possible is arguably the only course of action. The number of yous who do and the number of yous who do not may be equal, in theory, but while there are an infinite number of possibilities, I also hold that certain possibilities simply will not exist naturally.
To explain this, think...how there are an infinite number of numbers between one and two. None of them are going to equal three. I actually feel the multiverse functions the same way, but our perception and our actions can influence which numbers are 'true' and which numbers 'cannot be true', so to speak. Ergo, by having a rich life and helping others have a rich life, by deliberately acting towards those goals, those branches are more likely to sprout many more branches of the same, and by throwing it all away, they are less likely to exist even if they can exist in theory merely by the thought of them.
I'm probably dabbling with things WAY over my head, but this is all related. You can create a number, and live on that branch. If you have seen that branch but want a different one, then the branch will always exist thanks to you seeing it, but you can still create the other one, and maybe move permanently to it.
So, this is why it'd be both theoretically possible to time travel and not change anything, time travel with a changed future you don't go to, AND time travel to a changed future you do go to, the three most common consequences of the time traveling. The first is based on observation: it happened, it was observed, so it exists, and you don't notice any difference because you couldn't; it happened already. The second is based on observation as well: your time traveling will by its very nature change things, but thanks to your observation, even if the changes you make are significant, the branch you create is not the branch you return to. And the third is when you deliberately invoke possibility, and go further up the new branch you created rather than the old branch you came from.
In other words, all three happen simultaneously. It's not a meaningless act, because of the number/branch belief, but it also is not that big a deal where worlds will end.
I kinda wish I could explain these thoughts more coherently. What I mostly mean by all this is...the you that you want to be is the you that you should strive to be. That version of you may always exist in theory, thanks to the infinite number of universes, but if you don't try, it also may not exist. Even if it does exist, if that you comes to be, if you've diverged off-course that much, then that you might be on a branch SO far away as to be inaccessible: it can no longer be observed because your actions, your choices, deliberately led away from it being observed. Whereas if you actively keep it in mind, you get closer to that observation, and that means more yous, more selves that infinitely diverge, are near that you, and you never know...one of those yous might actually be YOU, you. The final you. The you of your final destiny.
So, choose what fate you want. Great things come from it.
I hope you enjoyed my take on existence.
