I thank you for your genuine post. I hope you will forgive my lack of knowledge in the particulars you are asking about. If then division by zero is the thing itself, that is (A/0 = A). Then nothing is lost. In relation to homogenous spaces and the like. I can say that it seems akin. In that in given thing is a package of value and space. One within the other. Both are either defined or undefined, and so on. I have little skill in advanced mathematics. I can also say that since relative mathematics is addressing basic arithmetic, then assuming it is true, it is also true of all branches of mathematics. As mathematics is clearly a branched system. Lol I would say, maybe it isn't, in any case much work would need to be done to translate the consequences to the rest of mathematics. I suggest the need of it by physics as the necessity for its laborious adoption. Maybe the "need" of it by physics is not true. I would think it is however.
