    Can be described if you can describe the existence of 1/infinity in physical world.

    Exactly, this is Physics here, rather forced physics and mandated due to Einstein's nonacceptance of gravity as force.

    what do you think 1 divided by infinity means?
    (I am too lazy to use tex)

    You proposed a sphere of radius 1/infinity...

    but if the diameter is 1/infinity as I proposed and 1/infinity is the limit then what would be the radius?

    Undefined or makes no sense.

    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)

    Does the sphere exist ? To you QQ ?

    why do you ask?

    Because of the suggestion of non-existence in your post # 48

    So the sphere is a point particle ?

    not quite... the volume of the sphere maybe but not the sphere itself..Important distinction perhaps.

    Discuss the difference

    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.

    Then why bother with this 1/infinity in the first place ?
