You mean the one _without_ a continuous space-time or the one _with_?

Einstein's "Relativity theory" has one _with_.

Then how that works out with regards to formalisms
like Riemann metric and "what tensors" is under-defined
anyways: what with regards to "space-frames and frame-spaces",
an actual _difference_ linear/rotational,
real space-contraction, a fall-gravity,
mass/energy relativistic equivalence as rotational,
a vanishing yet non-zero cosmological constant,
with regards to that Einstein's relativity theory
is a theory with one negative stipulation:
that motion is relative.

Doesn't say anything about acceleration, either,
then that the equivalence principle is another
thing that varies in terms of there being absolute _space_ (GR).

Where, at least there's a universal _time_.


Don't get me wrong, I'm not so particularly attached
to one or the other interpretation. These though
seem best.


Least action, ....


Of course _mathematics_ is behind too, don't forget that
foundations of _mathematics_ need improvement when looking
to foundations of _physics_.
