> [!tldr] Everything is a node. And every node is connected to every other node. There's a star in a galaxy across the universe I've never heard of. Somewhere near-ish the center of that star is a proton. That proton is exerting a gravitational influence on my left index finger. That relationship is negligible in every practical sense - but it is there. Every single thing exerts physical forces on every other single thing in its gravitational cone. This is true of everything the observable universe. Everything is connected to everything else. Each thing can be modeled as node. Every connection, all infinitely many[^1] of them, could be modeled as an edge. Or a series of edges carrying the streams of influence they exert on one-another (any form of action at a distance). We perceive a vanishingly small, infinitesimal amount of these edges. But they're there. Consider this the [[Pareto Principle|80/20 Rule]][^2], I suppose. **** # More ## Source - self [^1]: technically wrong, but whatever [^2]: except raised to a googleplex
