LONDON (Reuters) - It's unlikely to occur by swallowing a pill or donning a special cloak, but invisibility could be possible in the not too distant future, according to research published on Monday.
Harry Potter accomplished it with his magic cloak. H.G. Wells' Invisible Man swallowed a substance that made him transparent.
But Dr Ulf Leonhardt, a theoretical physicist at St Andrews University in Scotland, believes the most plausible example is the Invisible Woman, one of the Marvel Comics superheroes in the "Fantastic Four".
"She guides light around her using a force field in this cartoon. This is what could be done in practice," Leonhardt told Reuters in an interview. "That comes closest to what engineers will probably be able to do in the future."
