-As attempts to understand how the classical world emerges from the quantum domain, post-quantum theories have been derived that reproduces quantum and classical physics as two asymptotic cases. Phenomenologically,​ these theories can be seen as quantum theory supplemented with an explicit collapse mechanism and might have a rich underlying physics.
