Using only mirrors, mathematician Miguel Lerma believes that he can make a time cloak that holds for relatively lengthy periods of time. A time cloak essentially creates a hole in space-time, on the part of the observer. So you could, ostensibly, be standing right in front of a camera, then walk away, and you would never be seen. Time itself would appear to jump forward. Of course, you would need a few mirrors and a really (REALLY) large space, but it is indeed possible. Theoretically anyway.
Previously, you couldn't use just any old mirror to create a time cloak. You needed metamaterials which are incredibly hard to make. However, Lerma's theory is that, with enough distance, you could use mirrors to the same effect, and they would, in fact, work much better than the metamaterials.
Lerma's setup involves eight mirrors, a light source, an object to obscure, and an observer. The best thing about Lerma's theory is that it requires technology (switchable mirrors) that are currently available to the commercial market. So, with the right application of science, you can now convince your friends that you actually have magical powers. Or are a Time Lord.
Similar principals were used to create an invisibility cloak not that long ago.
