…that no matter

how close

you get

the pupil

seems to

devour light

like a black hole

it reflects no light

That’s because the pupil is literally a hole in the iris that lets light enter the retina. No light is reflected by the pupil because it is either absorbed directly into the tissues of the eye, or it is absorbed after it is refracted around the inside of the eye.

Then black holes are merely the eyes of the universe

Whoa
