Models attempt to describe reality. They must be simpler than reality, but to be valid must capture some essential aspect of reality. Greening's model requires the mass to accumulate as the "collapse" proceeds. All of the evidence, I repeat, all of it indicates that this is not the case. We observe mass quantities of very dense stuff outside the footprint. When it's over, there is no pile. There is a smoldering crater.
Why don't you guys get to the part where you explain how all of the accumulating mass which stays inside the footprint, suddenly turns into a smoldering crater, as clearly shown in this picture?
What are you talking about?
Are you are incapable of doing the math to critique Greening, or Ross, or anyone?
You first post proved you wrong on visual evidence.
So when are you going to finish a physics course?
