For decades now some very important fundament principles of mathematical Physics have been incorrectly applied to the theory of gravitational lensing or just simply ignored. From astrophysical observations it is apparent that the current understanding of the effects that gravitation should have on light is fundamentally incorrect. Astrophysical observations pertaining to lensing are consistent with effects due to an indirect interaction involving an interfering media, not a direct interaction taking place in vacuum space. It is however theoretically possible that current technical means may not permit a distinction to be made between an indirect and a direct interaction between gravitation and light. The thin plasma atmosphere of the sun represents an indirect interaction between the gravitational field of the sun and the rays of light from the stars. There is convincing observational evidence that a direct interaction between light and gravitation is yet to be observed. Historically, the observed evidence of light bending occured predominantly near the plasma rim of the sun, not in the vacuum space far above the rim. The events taking place at the site of Sagittarius A* presents convincing observational evidence that a direct interaction between rays of light and gravitation in vacuum space simply does not take place. This is clearly revealed in the time resolved images of the rapidly moving stellar objects orbiting about Sagittarius A*, a region at the galactic core believed to be a super massive black hole. This is a region that has been under intense observations by the Astrophysicists since 1992. A clear lack of observational evidence for optical lensing due to gravitation is apparent when examining the undistorted images of the stars moving along Keplar paths about Sagittarius A*. The space in the immediate vicinity of a black hole is by definition an extremely good vacuum. The evidence for this is clearly seen in the highly elliptical orbital paths of the rapidly moving stars orbiting about the galactic core mass. The presence of any material media near the galactic core mass would conceivably perturb the motion of the stellar object s16 moving with fractional light velocities, thus causing it to rapidly disintegrate. Astrophysical observations reveal that s16 has a velocity approaching 3 % of the velocity of light when passing to within a periastron distance corresponding to 60 astronomical units from the black hole thus giving solid evidence that the space in this region has to be, without a doubt, an extremely good vacuum. It follows from this that a direct interaction between the light emitted from the orbiting stars and the gravitation of this super massive galactic core at the site of Sagisttarius A* is yet to be observed.
