Bhobba said "Decoherence usually requires interaction with something macroscopic and an environment". I assume decoherence still occur to the atoms and molecules inside any object because they are exposed to the thermal vibrations and CMBR. Let's say for sake of discussion we can freeze an object such that the thermal vibrations no longer serve as environment and put it in container that would completely avoid any CMBR exposure. So decoherence won't happen to the atoms/molecules? Using collapse interpretation.. without decoherence.. they won't collapse.. so does it mean the atoms/molecules and object suddenly become vectors in Hilbert space and vanish from physical sight? To what extend has experiments like this been done?
