I have discovered it is an archaic term used by Newton. Newton thought he
needed to assume the existence of absolute space and of absolute motion "For
it may be that there is no body really at rest, to which the places and
motion of others may be referred." . . . Newton envisaged absolute space as
an absolute order of "places"; this order of places is a "primary" system to
which motion ultimately can be referred. It is obviously an archaic concept
as I have only been able to find philosophy sources that reference it - it
has been purged from modern physics. This is obviously the appeal it has to
cranks - firstly is has the philosophical bent they seem to like and
secondly because it was believed by a genuine great physicist, Newton, it
lends an air of legitimacy to their rantings. Of course there is a reason I
was only able to find philosophical references to it (other than a reference
it was an idea of Newton's) - it now well known even classical mechanics
does not require it - all it requires is the POR, the PLA and the Galilean
transformations. Even though I have spent too long replying to this fool at
least some good come of it - I learnt a bit of the history of science - or
at least it refreshed my memory - I seem to recall reading about it is the
writings of Russell etc. It is referenced as a concept of Newton in Ohanian
and Ruffini but no detail is given.
