How could a human eye become an Optical Black Hole?

You need to elaborate. What is an optical black hole?

By reading the wiki page, the eyeball would have to be cooled to a fraction of a degree above absolute zero and spun faster than the local speed of light.

I was bit confused by this as well. None of this can be done with a human body.

OK, how about this:

@radcliff Still, how does an eye fit into this?

Ah. A Bose-Einstein condensate is a supercooled substance that has quantum properties. Being quite dense, light slows through it, and theoretically, if you spin the BE condensate, you could spin the substance faster than the speed of light.

I’m not a physicist, but I’m thinking a human eye has about as much of a chance of becoming an optical black hole as any other piece of meat would.

But, the human eye already is an “optical black hole” of a sort; kind of. It is already capable of “trapping visible light”; once light enters your eyes it doesn’t get out again. :-)

Light enters they eye through the cornea, the cornea kind of bends the light through the pupil, then it goes through the lens, which refracts or kind of bends it toward the retina, where the “cones and rods” convert the light into electrical impulses and those impulses are transmitted through the optic nerve to your brain which perceives the image.

The light that enters the eye is “trapped” by it, kind of like a black hole.

It cannot. At least not while maintaining it s properties of a human eye.

It would be very uncomfortable.

If you mean that “an optical black hole” traps light thatt does not continue as light, there are many and they have very little in common with astronomical black holes which use gravity to trap light and have many other interesting properties. Another interssting propertly is something called Cerenkov radiation which is caused by particals moving faster than the speed of light in that medium – since light does slow down in matter. And that is interesting but has nothing to do with the idea of faster than light speed travel in space. It is a pretty blue radiation in water.

I am thinking of “one way” glass that lets light through but is reflective to keep it in place. They use that in lasers.
