“The sole argument generally given to justify this picture of the world is that perturbative string theories have a massless spin two mode and thus could provide an explanation of gravity, if one ever managed to find an underlying theory for which perturbative string theory is the perturbative expansion.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The argument for string theory’s relevance to gravity relies on its massless spin‑2 particle, but this is only a perturbative hint without a full underlying theory.
In simple terms: String theory’s gravity claim is based on a limited perturbative feature.

A Different Perspective
Without a non‑perturbative framework, the claim remains speculative.
