the claim
A Slinky changes its equilibrium length when placed on the moon
the verdict
COMMON KNOWLEDGE
no citation needed for this one
refutedsupported
the weight of evidence
no sources on either side

A Slinky (or any spring-mass system) depends on gravity for its equilibrium length, so placing it in the weaker gravity of the moon alters the gravitational force acting on its mass, changing its stretched equilibrium length. No citation is needed for this basic physical fact.

The analysis

The claim is a direct deduction from basic mechanics (Hooke's law combined with gravity), making it common knowledge. None of the retrieved papers discuss the equilibrium length of a Slinky on the moon.
