What would you do if you could conceal yourself both in space and time? Someday that may be possible to do.
Scientists at the Imperial College London have built on previous work to make this possible -- at least in theory. Scientists have already established that the use of fabrics made with "metamaterials" could bend light around an object making it appear invisible. Does that remind you of Harry Potter's invisibility cloak?
Metamaterials are artificial materials designed and minipulated at the molecular level to interact with and control electromagnetic waves, according to the story on CNN.com.
Scientists now have extended this invisibility cloak idea to time as well. The theory goes that as light enters the metamaterial, some parts speed up and some slow down, creating what they call a "blind spot" in time. Some light gets there before the event and some light after it occurs.
Do you think this would be useful for any real-life applications? No criminal uses, please!
