1)
If NL1 is construed as indicating that a body continues in a straight
line when no unbalanced forces operate on the body
and
If geodesics on a Reimannian manifold are not straight lines
then
Will people grow concerned about compatible definitions for the NL1 they
teach, and what concepts like Inertia that they need to avoid as Leading
to conceptual conflicts?
2)
If the current space time model is hard won
and difficult to acquire conceptually,
why would people NOT defend it as the “truth”,
and explain that observables that conflict are “only shadows”?
3)
If a straight horizontal track is laid out on Earth, where will a
friction-free ball placed on it, roll to? If the track's straightness is
checked with a laser beam, will that assure its straightness?
