Consideration of relativity with reference to time and distance for interplanetary spacecraft; theoretical consideration under which time span of one human life would be long enough for travel around the total static universe.
Effects of uniform motion on space and the simplest currently accepted relations between space and time are stated.
Is concerned with an explanation of the general theory of relativity.

Translated title: Space-time in the unitary field theory.
From the point of view of ordinary relativity, there are two invariant planes in spin space. We need, therefore, only admit transformations which leave these planes invariant. In projective relativity these two planes do not lose their invariance, but they are no longer constantly covariant, and we must therefore adopt general linear transformations in the spin space. In the present paper the author shows how the spin space is connected with the local space-time world, what invariant structures exist in spin space, and how an invariant calculus may be constructed.
Intends to show the simplest access to possible geometrical models of space-time.
