So far it seems remarkably steady. That inertial mass and

mass are the same has been carefully tested in the lab.

?t's been tested, for centuries, in space! Any difference between
inertial and gravitational mass would immediately manifest itself as
deviations in the orbital motions of planets, stars and other objects
in space, including our space probes. The orbital motions in the
solar system tests this to an accuracy that's higher than what we can
acheive in earth-based laboratories. An interesting consequence is
that we know the Sun's mass in Earth masses to a higher precision
than the Sun's mass in kilograms. And the Gaussian gravitational
constant is knows to a higher precision than the gravitational
constant in SI units.

And when Time is finally understood we will instantly recognise phase-shifted, cross-barrier, gravity leakage between the Multiverses. Whereupon, Dark Matter and Dark Energy will be relegated to the history books. ;ø]

....you speack about the dark matter ...which meaning do you give to the CAT I/239/tyc main , in CDS Strasbourg , where almost the 50% of stars have a negative parallaxes ? almost everywhere we try to look , the ligth is deviated by many intermediate bodies ...
( if you aswer , advice ..thanks )
