  "textContent": "Not knowing the true nature of space-time seems to be same for everyone, including Albert Einstein who invented / discovered / stumbled upon / math'ed it back in 1915.\n\n\n\n\nNot knowing though is massively fun, it's the reason science exists, that and a burning curiosity within each and everyone of us.\n\n> Space-time is frequently described as the “fabric of reality.” In some accounts, this fabric is referred to as a fixed, four-dimensional “block universe” — a complete map of all events, past, present and future.\n>\n>\n>\n>\n> In others, it’s a dynamic field that bends and curves in response to gravity. But what does it really mean to say that space-time exists? What kind of thing is it — is space-time structure, substance or metaphor?\n\n**_What, exactly, is space-time?_**, August 24, 2025 by Daryl Janzen\n\n\n\n\nWho fucken knows tbh, but it's fun to see where we are at.\n\n\n\n\nI get the impression that gravity and time, the current last two blocks to be understood and 'slotted' into Quantum Field Theory and/or General Relativity, will come to the fore and answer many outstanding fundamental questions of the universe we are a part of. Be bloody nice if someone could do that before I die, I'd love to be around in such a Newton / Einstein / Bohr moment … hah, maybe it's happened and, like all the other revolutionary theories, it's not been properly understood or accepted yet. Maybe.\n\n\n\n\n\n\n(subscribe/RSS)",
