The 1,600-Year-Old Cup That Uses Nanotechnology?!

This isn’t just a Roman relic.
It’s a 1,600-year-old artifact that changes color depending on the light — and it uses what we now call nanotechnology.

Known as the Lycurgus Cup, this ancient glassware contains nanoparticles of gold and silver, sized just 50 nanometers.
That’s smaller than a virus — and way ahead of its time.

How did ancient craftsmen achieve this?
Was it accidental, the result of forgotten science, or evidence of something deeper we’ve yet to understand?

Let’s break it down — science, mystery, and a bit of brain-exploding curiosity. 💥
