Something mind blowing that I figured by thinking about metaphysics deeply is that our minds are sometimes obsessed with figuring out what's the origin of all and why there's something instead of nothing at all, how could something exist and at the same time be the origin of all without having been created.
I realized that we don't even know if these are the right questions to ask, because we are unaware of the layers of abstraction reality features.
Many scientists think about energy as fundamental but they assume it's at the basis of reality, yet we cannot prove that it's the ultimate abstraction reality is made of, and we will never be able to prove it and we will never have a proven theory of everything because of this very fact. What if energy as we know it was just the manifestation of a greater interconnected reality for instance, one we can't even imagine?
So when we talk about dimensions it's often thought as space and time with energy being fundamental and permeating the spacetime in a multi-dimensional framework, yet we don't know the full extent of the abstraction of reality.
Also fun fact: the other day I was thinking about my post count here on WorstGen by remembering the old times I would post like a bot (I was even called Finabota for it) and I realized that our existence as humans is based on an important count, which is the number of heartbeats in our lifetime. This number is highly variable depending on our genetics, environmental factors, lifestyle etc. yet in a sense it's like if we had a post count and it was constantly dropping by 1 and we don't know what's our "heart count" because we don't know how many heartbeats we have left in our lifetime, we only know it's slowly dropping to 0 (unless we are so unlucky our heart will forcefully stop); but if we assume the universe is almost deterministic (because according to quantum theory there are so many probabilistic quantum events that the outcomes tend to average out when we move to classical physics so basically we end up with a fidel determinism) then in theory our future is practically already written down. But once again we don't know if there's something deeper than quantum theory.
Also I think
@minamoto would probably enjoy my post lol.
