Singularity is difficult to understand due to the fact that the idea of space and time are not applicable given the definition.

true false

I assume you are talking about the space-time singularity.

Yes, the gravitational singularity is absurd since the gravitational field is infinite so that the celestial body does NOT depend on the coordinates anymore, i.e. the normal space-time theorem does NOT apply anymore.

However, this can be predicted by general relativity, where the singularity can appear at the center of the black hole.

 So if you are talking about classical physics, yes it's difficult. But if you are talking about modern physics, then it's predictable and analyzible. 

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
