Figure shows the Diósi-Penrose collapse times for diverse fullerenes between C20 and C720. The collapse time for C70 is 2.4×10 14 s. If the experiment were repeated with C720, a much larger buckyball, the collapse time would be 8.4×10 12 s. Before moving to another application, let us check the effect of the approximations introduced in the homogeneous models ( ) and ( ) compared to the geometry-specific model (6). 3). At the maximum E, the collapse times of the two models are 2.4×10 14 (geometry specific) and 2.7×10 14 s (homogeneous). The homogeneous model in the approximation rR   (eq. ( )) agrees well with the other two results for small values of R but diverges later, with a much lower saturation E, corresponding to a collapse time of 8.0×10 14 s.
