The trouble with models I find is that they are essentially mathematical abstractions. I feel they can model "reality" up to a certain point, beyond which the models break down. 0 dimensional points in QM, 1-dimensional strings in string theory. It is like looking through a microscope. All is well till we get the limits imposed by the equipment.
