Wisdom cannot be directly transmitted, and does not readily accumulate through the ages.

The outstanding feature, however, is the possibility that the velocity-distance relation may represent the de Sitter effect, and hence that numerical data may be introduced into discussions of the general curvature of space.

Past time is finite, future time is infinite.

The universe is unfolding as it should.
