Description
According to density matrix realism, the quantum state of the universe is objective but could be fundamentally mixed. I develop this framework and motivate it using considerations about the arrows of time. I then present a new class of results—observation typicality—which establish fundamental limits on our ability to infer or distinguish universal quantum states from observations. I explore how these epistemic constraints bear on the choice between density matrix realism and wave function realism.
