ELI5: What would happen if there was a material that absorbed 100% light?
gpt
If a material absorbed 100% of light that hit it, that means that nothing would be reflected back into the photosensitive cells inside your eye. That means you wouldn't be able to discern any detail about the object. Imagine being in a completely dark room - you wouldn't be able to make out an object right in front of you because no light would be reflecting off of it.
