Exactly, this is Physics here, rather forced physics and mandated due to Einstein's nonacceptance of gravity as force.
but if the diameter is 1/infinity as I proposed and 1/infinity is the limit then what would be the radius?
so the contents or volume of the sphere is nonsense or ... dare I suggest non-existent. (zero dimensional)
The reason I brought this extension up is that we were discussing mathematical abstractions colliding with physical realities. Here we have both I think.... With this sphere of infinitesimal diameter you have a mathematical abstraction that could be deemed a physical reality. ( sort of)
See the answer with (currently) 18 +ve votes here: https://math.stackexchange.com/questions/1372459/one-divided-by-infinity-is-not-zero Common sense has to be applied sometimes, rather than rigid formalities.
not quite... the volume of the sphere maybe but not the sphere itself..Important distinction perhaps.
I would have intuitively considered 1/infinity as being an infinitesimal. Certainly not zero. I presumed that this was common knowledge... My mistake... sorry
Maybe you missed what i was hinting at QQ. Nitpickery over the formal distinctions may excite pure mathematicians, but leaves me shaking head. Which is why I like physics - definitions have to mean something useful and testable in the real world.
