So this is basically just refraction right? why all the mumbo jumbo?

There is no index of refraction difference to talk about. It's a lens, but just by different means.

Isn't this pic wrong? When gravity has no limit, then straight lines are not possible. I mean, a star 5million lightyears away still affects spacetime around earth. Just a little little tiny bit but it has an effect. So no matter where in the universe, light can't travel in a perfect straight line because aslong as there is one single bit of mass in the universe, spacetime is always bended. Right?
How do we even know where light comes from when there are quadrupillions of waves in spacetime?

The photon never got absorbed. Just left its star, cruised some minimal geodesic and BANG! Pops you right is the eye like the bitch you are. No refraction.

Can photons orbit other thingd besides black holes?

It's gravitational lensing you retarded zoomer.

Thats is a racist term. Please use inclusive language. 4chan is a safe space for folkx of African descent.
