How to Make a Whole City Invisible

It's been 20 years since the first promising prototype of an invisibility cloak. We're still pretty far from having the cloaking devices of sci-fi dreams, but some engineers think the principles of invisibility could be used to shield entire cities from earthquakes. In this video, we explore the science of invisibility and its potential applications. From metamaterials that bend light around objects to seismic cloaking that redirects earthquake waves, the possibilities are fascinating. We talk to engineers who are working on these technologies. Hosted by Savannah Geary, this video delves into how invisibility research could one day protect cities from natural disasters. It's a look at how far we've come and how far we still have to go.
