There We Measure Shadows, And We Search

Equipped With His Five Senses, Man Explores The Universe Around Him And Calls The Adventure Science.

The Great Spirals, With Their Enormous Radial Velocities And Insensible Proper Motions, Apparently Lie Outside Our Solar System.

Observations Always Involve Theory.

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.

The Universe Is Unfolding As It Should.
