These are the scales at which neither General relativity nor the standard model (QM, QFT, etc) dominate, so you cannot just ignore one and do the calculations with the other. To solve systems at these scales, you need a working system of quantum gravity. We do not yet have one of those. These quantities are essentially where our current models of physics break down and we can no longer make anything resembling a prediction.
