So what does the SE for this discrete universe look like? The one
every
cites assumes a continuum. If the universe is finite then there's
smallest non-zero probability, which as Bruce says, raises some
problems.
Not the least of these problems is the fact that a smallest non-zero
probability makes the collapse real; destroys the
ongoing superposition; renders everything absolutely irreversible; and
screws the hell out of unitary evolution.
As do other real-collapse theories of QM.
