A recently proposed experiment considers the possibility of reaching regimes where quantum behavior might be observed in nanomechanical systems. This proposed experiment is examined here for feasibility on the basis of results of earlier studies identifying a boundary separating obligatory classical behavior from quantum behavior based on effects dependent on large scale properties of the universe. Calculations indicate that cosmologically induced effects leading to a quantum to classical transition will not interfere with the proposed experiment at the level at which it is described. Thus, this experiment may be expected to be able to succeed for the case of nanomechanical systems such as the 50 nanometer radius spheres under consideration; however, the success of similar experiments for larger micro scale systems may be ruled out.
