Matter extends in gravity. Matter occupies curved space-time and is

The hypersphere is the 4th space dimension. The universe and
everything in it is curving in the 4th space dimension. The universe
is the curved surface of the 4th dimension or hypersphere.

There is nothing beyond the expanding hypersphere.

The hyphersphere is discribing the surface of spacetime with same lenght of
proper time as the observer has. Space is a projection of this sphere on a
comoving (hyper-)plane. Its not the same as space, because spacetime has
other dimensions and is complex valued. We get from spacetime to space by
the observations of an observer. That turns physics into
measurement-results. Measurements produce real-valued results, and that is
how we see our world, but does not make spacetime real valued.
The term 'beyond' makes no sense in relation to space, because in relation
to spacetime space is something like time. Far distance is something like
older. Space and time have to be understood as mainly the same thing, what
is the core of relativity. The term 'beyond' makes sense in relation to
time, cause there will be a future (hopefully).
