Basic info of the error of GR

GR is based on a major error of rational thought.
That is the creation of something REAL and Physical, having physical properties, from the combination of exactly NOTHING, (Space) and a CONCEPT, (being the concept of Time)
"Spacetime" is a moronic reification of abstract ideas, therefore there is no such thing possible for consideration in the study of Physics. You cant have a "Geometry" of CONCEPTS.
How many CONCEPTS can fit into my box? Whats the tensile strength of my Concept? How far can my Concept of Spacetime be bent before it snaps?

If you REIFY concepts and call it Physics, you will always end up with NONSENSE.

But if they are correct, then ALL Astronomical observations are WRONG, because Astronomy relies on "line of sight" classical Physics principals of STRAIGHT Light paths, to calculate distances, motions, calculate velocities, masses, etc.

Seems you can make totally contradictory claims in Physics these days, YET still be "correct".
