Scientists Trap Light in a Super-Thin Layer 1,000 Times Smaller Than Hair

Scientists just figured out how to squeeze light into an incredibly tiny space—so thin you'd need a microscope to see it! By using special materials that bend light in amazing ways, they trapped infrared light (the invisible heat light you can't see) and even turned it into blue light we can see. This discovery could help us build tinier, faster computers and gadgets in the future!
