OBSERVABLE SPACE IS ALWAYS EUCLEDIAN - THE CURVATURE NON EXISTING MYTH

OBSERVABLE SPACE PRACTICALLY AND THEORETICALLY BEHAVES EVERY WHERE AND ALWAYS EUCLEDIAN.
AFTER THE FIASCO OF BENDING OF LIGHT, PASSING TANGENTIAL FROM THE DISC OF SUN. AFTER THE FIASCO OF PERIHELION OF MERCURY ROTATION AND THE ROTATION OF VENUS, EARTH, MARS PERIHELION, THERE IS NO ARGUMENT THAT SPACE IS NON EUCLEDIAN.
INDEED. ALL CELESTIAL MECHANICS, EITHER HUMAN-SPACE DYNANICS OR NATURAL ORBIT USE EUCLEDIAN GEOMETRY.

WHERE THE MINKOWSKI, RIEMANIAN OR THE LABATSEVSKI SPACE IS USED?    NO WHERE.! SO OBSERVABLE SPACE BEHAVES ALWAYS EUCLEDIAN, AS KNOWN TO THE GREEKS 3000 YEARS NOW.!
