One of the most fundamental truth is I think therefore I’m of Descartes
This implies the existence of I myself.
I personally think, without the existence of I myself, other things will can still exist. So there’s another deeper fundamental truth that I can describe is “to be” or “something exists”
Is the most fundamental characteristic of anything is either it exists or not?
I struggle with this for a while while also thinking about how the ultimate quantization of the universe can interact with each other.
Interaction by itself means there’s an even smaller process, which defeat the concept of the ultimate quantization.
However, I think I’ve some valuable insight linking between this ultimate concept of interaction and existence.
Here’s a thought experiment. If something indeed exists but there’s no possible transmission of information or physical interaction between our world and that thing, will that thing still exist? Probably not. At least from our world point of view. Simply because there’s no possible interaction. It’s outside of our realm of existence. Even if it does “exist” along side with other things it can interact with.
That galaxy exists because ancient photon from it hits our eye, everyone sees it.
Valhalla doesn’t exist, at least to us, because no information from it reach anyone of us. Even if it does “exist” in a completely different realm, it’s not really relevant or constructive as a concept of existence itself. So we can just say it doesn’t exist.
So here’s my crude and alternative definition of existence: if something exists, it means there’s possibility to interact with it. If we can’t interact with it or no information, it doesn’t exist
However, we need to be careful because there are things that indeed exist, we just can’t detect it or find ways to interact with it yet. But it does exist.
Anyway, so if existence is merely the fact that if we can interact with something, it doesn’t sound really fundamental to me. It sounds like there are other realm of existence.
There’s a conundrum of how can we know if something exists in other realm, or not exists in any realm at all. Or is that really matter because there’s no interaction?
Occam’s razor: I don’t think we should care much about other realm. Only this realm.
This bring me to the fundamental truth: existence means there’s some information and possible interaction.
But here may lie another deeper fundamental truth: what is this interaction and how exactly can it happen?
It seems to me if one thing want to interact with the other, the 2 things have to have something in common. That’s the minimum requirement. However, we can not just say they are in the same space or space is the common thing. What if space itself has an ultimate quantization. Then what’s the thing that’s common between all space quantization?
I personally think an ultimate quantization can not have states. States just means there’s something smaller, a smaller quantization.
