Scientists use 'negative light' to send secret messages hidden inside heat
SMRTR summary
Scientists developed a breakthrough stealth communication method using "negative light" that makes data transmissions completely invisible by disguising them as ordinary background heat radiation. The technology transfers information at 100 kilobits per second through special diodes that create subtle brightness patterns undetectable without specialized receivers, with potential speeds reaching gigabits per second.
