I hadn't heard of diffraction grating but it sounds like they can steer light by having it travel through layers of changing air density resulting in a kind of air lens. That's rad.
Still, they say that the most obvious and possibly most beneficial application of bending laser beams with nothing but sound waves is in high-energy laser applications like fusion research, material processing, or even particle accelerators where the ability to change the direction of lasers without actually coming in contact with them could prove to be a game-changer.
These applications aren't really relatable but I imagine lensless lenses have a bunch of applications.

For the first time ever?
So every time flat earthers take a laser out over water and prove that the earth is flat, but globe earthers say "no, no, no, it's diffraction through different layers of air density that causes a laser to follow the curve of the earth" the flat earthers were actually correct?
