Abstract
Astronomical evidence has been inadequately invoked to support projective relativity. The spiral structure cannot be explained just by the existence of spiral orbits, and the use of Oort's constant to support the theory is also a missunderstanding. Besides, some mathematical inaccuracies make the application invalid.
