"A new study demonstrates that under certain conditions, light can create shadows by blocking other light, similar to how solid objects cast shadows. Credit: SciTechDaily.com" (ScitechDaily, Defying Physics: Lasers That Can Block Light Itself) That thing can make many new things in the world of communication, weaponry, and many other things. The laser's ability to block light makes it possible to create electromagnetic wormholes through the air. That allows communication systems to transport information in a highly secured mode through the air using laser rays. The hollow laser rays make it possible to send photons through long distances and the outside light doesn't disturb those photons. The ability to black light means that laser rays can also block IR radiation which makes it possible to create an electromagnetic shield that protects the target against infrared radiation. That allows the creation of extremely good protection against thermal radiation. It's p...
