This is all just supposition, but... The smallest indivisible parts of matter (also for us) are elementary particles... The smallest indivisible part of space is a point... It may be possible to say that each of these elementary particles themselves are points. And there exist no points outside of the total number of elementary particles that currently exist... So, Point A would not be 'somewhere in space', it would be 'a point locatable' (in regards to other points that exist)... For movement to occur, it would happen at the elementary level, and what would be happening is the swapping of places of points... The swapping of points being the resultant to the physical forces at play... Not all of the 'moving' body may be moving at one time (eg. Your stomach vs. it's contents when you're on a roller-coaster). So, the movement of a body is the sum of all the movement of it's elementary particles... Point A, B, and C are all relative, in regards to things outside the system of A,B, and C... And are found based on their 'defining attributes' (in other words the concept of them)... For this to work, it would be based on a few things:- each elementary particles is in fact a point, and there are no points that exist otherwise... for something to move, it comes from the movement of the sum of it's elements... no elementary particle can claim space occupied by another elementary particle... Essentially this suggests there being no real Point A or Point B, except when you look from outside the system, a system which brings context to where exactly each particle or 'space' is... If an elementary particles is a point, and is then located in a different spot (in regards to elements outside the system) at any moment it may have been somewhere between Point A and Point B.. (Point A and Point B being merely relative)...
