a)
The fourth dimension (an absolute spacetime) is the
negative two (-2) dimensions flat negative Pseudo Euclidian spacetime.
( + 4-D = -2D )
Many cosmologists believe that '' spacetime is curved ''
====
The spacetime (as whole ) is cold continuum.
The light travels in this continuum in a straight line.
But near the hot masses of stars light can be curved.
Not spacetime curves but the movement of light is curved by hot masses.

Local Curvature of Space
According to Einstein’s theory of general relativity, massive objects warp the spacetime around them, and the effect a warp has on objects is what we call gravity.
So, locally, spacetime is curved around every object with mass.

Only '' around every (local - hot) object with mass.'' light is curved.
The mass-objects in the universe (as whole) is very few.
Therefore the universe (as whole) is a flat spacetime (vacuum) continuum.
#
Different objects and all different waves act in vacuum.
(one of vacuum's name is spacetime because in vacuum space and time are united)

if so which is the active part there ??
space or mess ????
you say
mass ** is wrapping ''(mass is warped '' )
it means that the active entity
is ....... mass!!!
and that s it!!! full stop!!

No, that is NOT it. The "source" of curvature in GR is the full energy-momentum tensor, not just mass. So even massless phenomena such
as electromagnetic fields and waves can generate spacetime curvature,
and thus gravity.

Mr professional parrot

see for instance the

Yes. In classical electrodynamics it is quite clear that the EM field is massless. In QED, the theory assigns zero mass to photons, and the experimental upper bound on the photon mass is 1E-18 eV, a fantastically
tiny upper bound.

So you claim, and keep repeating, without any justification whatsoever.
I point out that we do indeed detect photons, even though they
presumably have zero mass.
I also point out that we detect sound waves, waves on the beach, and
many other types of waves, all of which CLEARLY have no mass -- they are
just specific kinds of synchronized movements.
