The cosmological interpretation of quantum mechanics, proposed by Anthony Aguirre and Max Tegmark, is an interpretation of quantum mechanics that applies in the context of eternal cosmological inflation, which arguably predicts an infinite three-dimensional space with infinitely many planets and infinitely many copies of any quantum system.
 According to this interpretation, the wavefunction for a quantum system describes not some imaginary ensemble of possibilities for what the system might be doing, but rather the actual spatial collection of identical copies of the system that exist in our infinite space.
 Its collapse can be avoided.
 Moreover, the quantum uncertainty that you experience simply reflects your inability to self-locate in space, i.e., to know which of your infinitely many copies throughout space is the one having your subjective perceptions.
