The ability to turn yourself invisible would open up a whole world of possibility. In new horror movie The Invisible Man, a woman believes she is being haunted by her abusive ex-partner who took his own life shortly after she escaped the relationship. She's set to inherit a large portion of his wealth and assets, but only if she can stay sane - difficult to prove when you believe you're being tormented by a ghost.

Invisibility was the stuff of science fiction then, but 100 years later, is it any more plausible? Scientists have determined that there is a fundamental physical limit to invisibility that we cannot break. While there are cloaking devices that work by bending light around a material, the larger an object is, the more difficult it becomes to hide completely.
