Found this article while reading through National Geographic. It says that scientists were able to figure out how to see through opaque objects by figuring out how to unscramble whatever light that passes through.
For those of you who will argue that opaque objects by definition do not let light pass through, I’ll note that the test material the scientists used an 80-micrometer-thin layer of zinc oxide.
