Light can behave as if it's entered a curved mirror where some colors are amplified and others fade. Physicists have peered for the first time into this 'through-the-looking-glass' reality of waves, where the usual laws of physics are broken.
🎯 Light beams with different degrees of twist look like donuts with varying numbers of swirls, and each such donut can act as a separate data transmission channel.
