MEXICO: Ever wish you could just disappear? Turns out this may not be as far off as we thought.
In the past decade, scientists have made huge advances in developing super materials that may one day hide us from the prying eyes of those around us.
And with a little bit of engineering and ingenuity, perhaps it may come in the form of an actual cloak, a la Harry Potter.
But an invisibility cloak doesn’t necessarily have to look like a wizard’s cape. It could be fashioned out of extremely thin wires made of silica and gold, carbon fibers, silk, or a series of lenses.
There are various prototypes that cloak objects in different ways, but the most promising technique involves light.
As anyone who’s tried to feel their way to the bathroom in the middle of the night at a friend’s house knows, you need light to see the world around you. In a similar way that a bat uses sonar to bounce sound waves off of objects to discern how far away they are, wavelengths of visible light bounce off objects and back into our eyeballs, allowing us to see them.
