when most people imagine nothingness they imagine darkness, but even darkness is still something, true nothingness is incomprehensible to the human mind, amirite?

Well it's what's in the darkness not the darkness it self

OP is using the words imagine, nothingness and incomprehensible as if they're interchangeable with the word meaning yet each has meaning or OP wouldn't be using them. Meaning is an individual human construct. It can even make "something" out of "nothing".

paradox. what is the experience of no experience

Darkness is not something, as it is the lack of light. You can't make it, you can only make things that limit the amount of light reflected. Same with cold actually. Coldness is just the absence of heat.

Darkness is the thing that describes the thing nothing (/no light). If there would be a place that'd have nothing it'd be dark.

close your left eye. just the left one.

What does your left eye see now?
