>>12251255i’ll say it again: casinos effect. also vacuum polarization is well verified. hawking radiation is related and it is the accepted (though not directly observed) way we make sense of black holes. more theoretically, vacuum fluctuations are basically the same thing as virtual particles, and virtual particles are key in many observed particle physics phenomena, including the higgs decay to two photons via a virtual top quark loop which is what enabled the higgs boson’s experimental discovery by the LHC experiments
