Gr GEOMETRY/POiNT-mass.

$$ Gr GEOMETRY/POiNT-mass.
How was length, as a measurable quantity, *defined* there?
$$ All Gr Tivity TEST-objects are POiNT-objects. ```Brian.
[This is WHY GR must focus POLiTiCALLY on Gr-GEOMETRY].

$$ GEOMETRY/Gr POiNT-mass = GisBourne Lake/NFLD-water-POP.
[Thus, ANY other than POiNT-geometry must be HEARLDed].

$$ GR DECLARED "NO PRiOR geometry"; NO GR-WORLD-line, NOW.
[Accounting for Gr MANiFOLD & "TiME-like" SEPARATiONs].

$$ SR has VARiABLE EQUiVALENT iNTRiNSiC REST mass = E/c^2.

Don't feel bad, it's NOT obvious. PD
