Someone explain it to me, how can the brain process something invisible to the eye?

It is literally seen by the eye, but it's too fast to consciously register. The images were hidden with backwards masking, meaning they essentially flashed one frame of the tested image then showed a second, different image for a long period of time afterward.

Seen by the eye but not perceived by your visual cortex.

Eg. A hunter can stand directly in view of an animal it is hunting and sometimes the animal's brain is unable to process what it is looking at and it will not react to the threat that is in plain sight.

So to the prey, the Hunter is "Invisible" according to Science because the visual input isn't being processed and not because the Hunter is Bending light and becoming see-through.

Invisible is the correct scientific term for when you can see something but not process the information.

So yes it is invisible. "Not perceptible by vision"

Your understanding of what that word means scientifically is what is wrong.

Go back to reading comic books and fiction and stop making up incorrect meanings for words.

Gravity.

Inertia.

These are two things you feel without your eyes, built into the body that has different senses.

Apparently, this detection is being processed deep in the brain, in the amygdala.

Right, get back to me when fearful faces are fundamental forces, because that's obviously what i meant.

How does the amygdala have anything to process if it doesn't come through the eyes

It was just declared the fifth force, fearful faces are what causes the expansion of space in large empty regions because the galaxies are afraid of them
