Maybe we are defining Universe incorrectly, as not encompassing all (eludes to an outside) but more accurately, being all.
Most people (and even some phrasing in pop-science) treat the Universe like a room that matter moved into. But if we define the Universe as "Being All," the word "outside" isn't just a physical impossibility—it’s a linguistic error.
Here is how that definition changes our understanding of the big questions we've been discussing:
1. The "Expansion" Problem
If the Universe is a container, we ask: "What is it expanding into?" This implies an "outside" (a void or a pre-existing space).
Your Definition: If the Universe is All, it isn't "expanding into" anything. Instead, the distances between points inside the Totality are simply increasing.
The Analogy: It’s not a balloon inflating in a room; it’s a balloon that is the room. There is no "room" for the balloon to occupy.
2. The Fine-Tuning Reframe
If the Universe is a container, we imagine a "Tuner" standing outside of it, adjusting the dials (the laws of nature).
Your Definition: If the Universe is All, the laws of nature are not "rules" imposed upon matter from the outside. They are intrinsic properties of the Totality. The laws are simply "the way the All behaves."
The Math: We often use the Cosmological Constant () in equations. In the "All" model, isn't a "setting"; it’s a fundamental part of the geometry of existence.
3. The Boundary of Logic (Set Theory)
In mathematics, your idea mirrors Set Theory. If the Universe is the "Set of All Sets," then by definition, there can be nothing outside of it.
The Catch: This leads to Russell's Paradox. If the Universe is "All," does it contain the idea of itself? Philosophers argue that once you define the Universe as "The Totality," you can no longer talk about it as an "object" because an object requires a background to be seen against. The Universe becomes the Background itself.
4. The "Block Universe" Connection
If the Universe is All, then Time must also be Inside.
If there is an "outside," you could imagine a "clock" out there watching our universe pass.
If there is no outside, then "Time" is just an internal arrangement of the parts of the Totality. This supports your earlier hunch: Time is just the "All" being in different configurations relative to itself.
The Philosophical Verdict: "Monism"
What you are describing is a school of thought called Monism (specifically Priority Monism). It suggests that the "Whole" is more real than the "Parts."
Usually, we think: Atoms → Objects → Planets → Universe.
You are suggesting: Universe → Patterns → Observations.
In this view, you, me, and your fleet of Acer Chromebooks aren't "in" the universe; we are local expressions of the All. We are like waves in an ocean—the wave isn't "in" the ocean; the wave is the ocean in a specific motion.
