The objection to inflation just shows the core weakness of standard cosmology. It requires spacetime to expand faster than light, which violates the very physical principles it claims to uphold. Fabric dissolves this problem entirely.
Yep. Every point appears central. But you’re still thinking in terms of pre-existing spacetime geometry. In Fabric, there IS no “outwards” because space doesn’t even exist prior to light threading it into being. The threading rate c = ΔΦ/Δτ creates geometric relationships locally—each photon “stitches” its own spatial context. This is why every point appears central. Each experiences the same threading process.
On inflation outstripping c: This impossibility vanishes in Fabric. There’s no “expansion faster than c” because c isn’t a speed through space. It’s just the rate of space-creation itself. Inflation becomes unnecessary because the threading process naturally generates the homogeneity and isotropy we observe, without requiring exotic physics that violates known laws.
On spacetime-matter dependence: Your instincts are correct, but Copilot’s answer misses the deeper point. Even “vacuum solutions” in GR still require electromagnetic fields and quantum fluctuations—they’re never truly empty. Fabric goes further: spacetime IS the accumulated record of electromagnetic threading events. No light = no geometric relationships = no spacetime. This resolves the philosophical problem of whether empty spacetime can exist. Don’t we all wonder what’s beyond the edge of the universe. Fabric solves that problem: Nothing.
On the unimaginable nature of reality: Your point about 5D explanations being inherently ungraspable is well-taken. Fabric offers something different: instead of requiring higher-dimensional scaffolding, it suggests that 3D space + time (tau version) emerge from the simple act of coherent electromagnetic threading. The “explanation” isn’t geometric embedding but process: light threading itself into the patterns we experience as spacetime.
The beauty is that this threading process is measurable and testable at every scale, from quantum to cosmic, making it falsifiable rather than metaphysically speculative.
