(relativity)
The space-time of special relativity; it is completely flat and contains no gravitating matter. Also known as Minkowski universe.

Analogously, osculating curves in the Minkowski space-time are defined in [6] as the space curves whose position vector (with respect to some chosen origin) always lies in its osculating space, which represents the orthogonal complement of the first binormal or second binormal vector field of the curve.
In this section we characterize null osculating curves of the first kind in the Minkowski space-time.
In this paper, we introduce the notions of the first kind and the second kind null osculating curves in the Minkowski space-time [E.

But it is frequently overlooked that physical kinematics (the behaviour of real rods and clocks in motion) cannot be derived directly from the symmetry group (the Lorentz group) of Minkowski space-time without the further assumption that the covariance group of all the physical laws governing the behaviour of all conceivable rods and clocks coincides with the said symmetry group.
Globally, space-time is likely to be closer to a DeSitter space-time than the Minkowski space-time used in the limiting behaviour here.
Let [alpha] = [alpha](t) be an arbitrary space-like curve in the Minkowski space-time [E.
Following the paper [8], we first adapt the tangent spherical image definition to time-like curves of Minkowski space-time.
Let [beta] = [beta](s) be a unit speed time-like curve in Minkowski space-time.
The CPT theorem assumes symmetries of Minkowski space-time in implying the similarities between particles and antiparticles.
