the claim

Quantum cosmology models allow universes to spontaneously originate from a quantum vacuum without prior spacetime.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that quantum cosmology models allow universes to spontaneously originate from a quantum vacuum without prior spacetime?

Yes. Theoretical physics frameworks such as quantum cosmology and path-integral models allow for scenarios where universes originate spontaneously via quantum fluctuations or tunnelling from a state without prior spacetime.
