WHAT "iNVARiANT mass".?!! WHAT "mass.".?!! GR HAS *NO* "mass".!!
EXHiBiT how any GR mass mathematically RELATEs to GR T_uv = G_uv.

Well GR, *NOW* has ..TWO (2) MiSSiNG-mass ..IT's ONLY TWO (2).!!

$ The interPLANETARY and interSTELLAR ambient MASS:
No ATMOSPHEREs are iNCLUDED in the THEORY of NEWTON or GR.
Newton's work and GR-Tivity DOES NOT include the GRADiENT,
( the DENSiTY gradient ) which EXiSTs around massive ORBs.
The THEORY of NEWTON & GR-Tivity call ALL this a VACUUM.!!

ANGULAR momentum pA = planet-like, mass*radius*velocity:

There's NO EARTH-mass in GR.!! There's NO SPACE-time curvature in GR.!!
HOWEVER, if there COULD BE a mass in GR ..NO Newtonian LiMiT (i.e. if),
THEN, subsequently, the EARth's *GR-WORLD-line-POiNT-mass* will "curve"
the trajectory of ANOTHER *GR-shuttle-WORLD-line-POiNT-_TEST_-mass*, iN
the GR-space, ON (..not, ABOVE) the GR-surface, of GR-WORLD-line-POiNT.
BUT, where-as Newton's TEST-mass m1 (in G*M1*m1) has a CALCULATED field
..mathematically speaking NOTE the corresponding GR-TEST-mass does NOT.
[Mathematically CENTRAL mass M1 "attracts" TEST m1, but m1 doesn't M1.]
[That's ANOTHER thing.!! There's NO centro-SYMMETRY in GR THEORY, duh.]
[Again iRONiCALLY, there is NO mass mathematically RELATED to GR T_uv.]
[Again PROFOUNDLY, there is NO mass-RELATED GR-SPACE-time "curvature".]
[Again, ADAMantLY, there is NO GR-mass-RELATED SPACE-time "curvature".]

LiGHT velocity c is NOW a MATHEMATiCAL constant ..just as is, pi.!!
LiGHT velocity c is NOW a, transcendental, MATHEMATiCAL constant.!!
LiGHT velocity v VARiEs, inversely, WiTH the PATH particle COUNT.!!

..AND its TRUE, that RiGHT and LEFT handed TWiNs,
arriving BACK from the SAME SPACEtime trip, will:
(A) Arrive BACK at somewhat DiFFERENT TiMEs or;
(B) LEFTY will be turned COMPLETELY iNside OUT.!!

$ NOT "that N-body systems decay into 2-body ones." ..but
that NEWTON simplified N-bodies to PROFOUNDLY TWO (2).!!
Newton PROFOUNDLY simplified N-bodies to just TWO (2).!!

No GENERAL THEORY of RELATiViTY c^4 / G ..it's ALL NEWTON's.!!
The PLANCK c^4 / G is NOT mathematically related to GR G_uv.!!
The NEWTON c^4 / G is NOT mathematically related to GR T_uv.!!
PROFOUNDLY, GR's G_uv = T_uv is NOT "RELATED" to Newton's G.!!
