The honest boundary

General Relativity & Quantum Mechanics are both extremely precise in their own domains, but conflict at black holes & the Big Bang. String theory and loop quantum gravity are COMPETING HYPOTHESES, NOT experimentally tested — neither is asserted to be correct.

Pick a "Scenario" (two pillars / where they clash / Planck scale / strings / loops / hard to test) · drag "Zoom" in the Planck scene to see spacetime foam · tap a concept to see "known / UNKNOWN"
