contrayed for zero,same that for others inertial referntial the interval is different of
zero,or number infitesimal,almost null
but how the infinite space can to transformed in some finite;but if the space were not infinite,it cannt be contrayed for zero,but to be contrayed it must be infinite,but
with connected with dimension-time,that generates"discreteness' or"holes"that generate new series of points not only of the space,but subspaces series generated by the time,that produce the deformations of the space,that are the
curves of space-time not equivalent,or with correspondence one to one between
the curve and straight lines,then to explicit the physical reality,the geometry must
be non-euclidean with positive metric with curvature and torsion,and exterior differential would be elliptic and the interior differential would be hyperbolic.
then space and time are intrinsically connected,where the space is infinite,but can be deformed by time,(with the breaks of rotational invariance),that generate the curvatures,where each one,has a temporal metric,it is the reverse of time-dilatations explain the contraction of the space,generating continuos space-time,
with discretions between its.
