The short answer, unfortunately, is no. And we all know this. So why do scientists keep pointing out all the ways in which an invisibility cloak wouldn’t work? Can’t they let us dreamers have our fun? Well, no, frankly, and here’s the latest of reasons why not. First, an invisibility cloak would only be able to block out specific wavelengths – and those wavelengths are far from the full spectrum of visible and non-visible light. But for those of you looking for a lower-tech way to kill the invisibility joy, the same scientists have noted that you could “throw a stone at” an invisibility cloak in order to detect it. Which is still nicer than their other detection method…
