Floating in space is equivalent to free fall under gravity
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
According to the principle of equivalence in general relativity, an object in free fall is locally inertial, meaning the sensation and physical effects of floating in space are identical to being in free fall.
