- Title: Many Worlds are irrelevant for the problem of the arrow of time
- Authors: Veronika Baumann and Flavio Del Santo
- Abstract summary: Gao has claimed that under the assumption that the initial state of the universe is a pure quantum state, only the many worlds interpretation can account for the observed arrow of time.
We show that his argument is untenable and that if endorsed it potentially leads to undermine the search for a scientific explanation of certain phenomena.

- Abstract: In a recent paper, S. Gao has claimed that, under the assumption that the
initial state of the universe is a pure quantum state, only the many worlds
interpretation can account for the observed arrow of time. We show that his
argument is untenable and that if endorsed it potentially leads to undermine
the search for a scientific explanation of certain phenomena.

In quantum versions of the same systems, classical ergodic traits can be broken.
We show that the birth and early evolution of a nonstationary state is remembered forever in infinite time averages.
We also visualize scar-amplified QBs unveiled within the time-averaged probability density of a wavepacket in a stadium system.

We show that, if the universal quantum state can be assumed to be a typical unit vector from a high-dimensional subspace of Hilbert space, no observation can determine which vector it is.
Our argument is based on a typicality from quantum statistical mechanics.

The derivation of Bell's inequalities gives precise meaning to the idea of quantum non-locality.
It also makes evident why using it for faster than light signaling is impossible.
It is demonstrated that series of outcomes, even if they violate Bell's inequalities, can be always embedded in a set of factual and counter-factual data.

This is despite its myriad of advantages to physics.
