Hi Curt:
Their solution is illusory and idle and no solution at all!
Technically, it's called computer simulations.
That means the
'Garbage in and Garbage out' is the rule rather than the exception:

It follows, therefore, that the supposedly proven symmetry between stars and black holes has been actually smuggled in and put directly or indirectly into the simulation program by hand.
And that is it. There is nothing else in it.
