How atmospheric refraction causes light to bend near massive objects. Not space bending lol

 It is the atmospheric refraction which causes the light to bend. Its very simple:

Atmospheric refraction - Wikipedia

Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height . [ 1 ] This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near the ground produces mirages . Such refraction can also raise or lower , or stretch or shorten, the images of distant objects without involving mirages. Turbulent air can make distant objects appear to twinkle or shimmer . The term also applies to the refraction of sound . Atmospheric refraction is considered in measuring the position of both celestial and terrestrial objects.

Terrestrial refraction usually causes terrestrial objects to appear higher than they actually are, although in the afternoon when the air near the ground is heated, the rays can curve upward making objects appear lower than they actually are. Refraction not only affects visible light rays, but all electromagnetic radiation , although in varying degrees. For example, in the visible spectrum , blue is more affected than red. This may cause astronomical objects to appear dispersed into a spectrum in high-resolution images. The atmosphere refracts the image of a waxing crescent Moon as it sets into the horizon. [ 2 ] Whenever possible, astronomers will schedule their observations around the times of culmination , when celestial objects are highest in the sky. Likewise, sailors will not shoot a star below 20° above the horizon. If observations of objects near the horizon cannot be avoided, it is possible to equip an optical telescope with control systems to compensate for the shift caused by the refraction. If the dispersion is also a problem (in case of broadband high-resolution observations), atmospheric refraction correctors (made from pairs of rotating glass prisms ) can be employed as well. Since the amount of atmospheric refraction is a function of the temperature gradient , temperature , pressure , and humidity (the amount of water vapor , which is especially important at mid- infrared wavelengths), the amount of effort needed for a successful compensation can be prohibitive. Surveyors, on the other hand, will often schedule their observations in the afternoon, when the magnitude of refraction is minimum. Atmospheric refraction becomes more severe when temperature gradients are strong, and refraction is not uniform when the atmosphere is heterogeneous, as when turbulence occurs in the air. This causes suboptimal seeing conditions, such as the twinkling of stars and various deformations of the Sun 's apparent shape soon before sunset or after s

The counter-argument made by astronomers (which you take as granted) that light is refracted in different directions and is not focused is wrong because we obviously see the star light very clearly despite being refracted by the earth’s atmopshere ! So their light is not refracted in different directions at all. That is called dispersion and only happens when light is refracted in a prism or in a rain drop. Astronomers need to learn basic optics physics before dismissing refraction in favour of absurd meta-physical theories like space bending light.

For example they dont even know that refraction changes the wavelength of light, which is why they confuse the refractional redshift with a gravitational redshift, which obviously doesn’t exist. And the so called ‘gravitational time delay’, as measured by Shapiro, is also caused by refraction, because the speed of EM waves decreases near the sun because of its atmosphere which slows light down to v=c/n, not because of its gravitational field. This is basic refraction physics which is learned in highschool, which Einstein of course failed
