-- *Mar*This is an important point — and it hinges on a very subtle but crucial misunderstanding about *size vs. density*.
Let’s go step by step. ------------------------------ 1. “The Singularity Was Smaller Than an Electron” In classical general relativity (from Albert Einstein’s equations), if we extrapolate backward, the universe reaches a *singularity* — a state where density and curvature become infinite. But here is the key: The Big Bang singularity was not “a small object in space.” It was: - All space compressed. - All energy of the universe compressed. - Infinite (or near-infinite) density. - Not inside space — it *was* the entire geometry. So comparing it to an electron-sized object is misleading. It was not small in the way a particle is small. It was high curvature because: - Total mass-energy of the entire universe was concentrated. - Density was enormous. - The curvature term in Einstein’s equations diverges. ------------------------------ 2. Curvature Depends on Density, Not Just Size The Einstein field equations say: Curvature ∝ energy-momentum density Not size. A spaceship: - Has small total mass. - Has very low density compared to early-universe conditions. - Produces very small stress-energy curvature. Even if it is compact, its mass is trivial compared to cosmic scales. ------------------------------ 3. Why Nano-Curvature *Is* Negligible Let’s use intuition instead of equations. Earth curves light measurably. The Sun curves it significantly. A neutron star curves it dramatically. A black hole traps it. A spaceship is closer in gravitational influence to: - A small asteroid. - Or less. The curvature from a 100,000 kg spaceship at 10 meters distance is vastly weaker than Earth's curvature at its surface. And Earth's curvature is already extremely small. So the spaceship’s effect is not zero — but it is many orders of magnitude smaller than even Earth's already tiny curvature. Physics is exponential and scale-sensitive. ------------------------------ 4. The Key Concept: Stability of the Vacuum You are implicitly asking: “If even tiny curvature exists, could it accumulate or destabilize vacuum?” General relativity and quantum field theory both indicate: The vacuum is extraordinarily stable. Small perturbations: - Do not amplify spontaneously. - Do not cascade into singular behavior. - Do not “slow electromagnetic waves into space-time phases.” Otherwise: - Every moving object would destabilize the cosmos. - The universe would be violently unstable. But it is not. ------------------------------ 5. Why the Singularity Argument Does Not Transfer The singularity was not powerful because it was small. It was powerful because: - Energy density approached infinity. - The curvature tensor diverged. A spaceship has: - Finite mass. - Finite density. - Very low curvature. Small physical size ≠ large gravitational effect. Large density and mass-energy concentration = large effect. ------------------------------ 6. Where Your Intuition Is Philosophically Strong Your intuition is relational: “If curvature is everywhere, nothing is negligible.” That is metaphysically beautiful. In relativity, yes: Every mass contributes to the geometry of the universe. But physics also teaches hierarchy of scales. Tiny contributions remain tiny unless: - Density is extreme. - Quantum gravity regime is reached. - Nonlinear thresholds are crossed. A spaceship does not approach those regimes. ------------------------------ 7. Important Correction About the Big Bang Modern cosmology (including researchers like Lee Smolin) suggests: The singularity may not be physical at all. It may signal breakdown of classical relativity. Quantum gravity may replace the singularity with: - A bounce. - A quantum transition. - Or some non-singular state. So even the “infinitely small singularity” is likely not a literal tiny object. ------------------------------ 8. The Deeper Insight Your real concern seems to be: “Is reality fundamentally delicate?” Physics answer: No — it is extraordinarily robust. Philosophical answer: Yes — everything participates in everything. Those two answers are not contradictory. They operate at different explanatory levels. ------------------------------ Final Conclusion The nano-curvature near a spaceship: ✔ Exists. ✔ Is real. ✔ Slightly bends space-time locally. ✖ Does not accumulate cosmically. ✖ Does not destabilize vacuum. ✖ Is not analogous to Big Bang singularity. The singularity argument fails because: - It was about density and total energy, - Not small physical size. Your reasoning is not irrational — it is extrapolating from a correct principle beyond its scale domain. And in physics, scale is everything. If you wish, we can now explore a more subtle question: Could quantum gravity introduce nonlocal sensitivity where small disturbances matter more than classical GR predicts? That is a much deeper and more interesting frontier. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
