Roger Penrose's need for a physics Grey area

[edmund cavendish]

TL;DR

Roger Penrose has postulated the need for a new physics in the "grey area" between macroscopic and microscopic. Is there such a need and if not why not and if there is what progress have we made toward it. If might end the pointless debate about macroscopic measuring devices?

Many discussions of the so called measurement problem seem to run up against the buffers of the uncertainty of what exisfs ? In the grey area between mjcro and macro scopic. Is there a zone a closing door of some new physics?

Er.. mesoscopic physics is an active area of physics. Have you looked it up?

There is no "zone a closing door"... whatever that is.

AFAIK there's no empirical evidence for the introduction of new physics in some mesoscopic scale, i.e., there's no known range of applicability of QT seen yet.
