Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists.
In earlier work the same team of theoretical physicists showed that invisibility cloaks are feasible.
Now, in another report that sounds like it comes out of the pages of a Harry Potter book, the University of St Andrews team has created an 'incredible levitation effects’ by engineering the force of nature which normally causes objects to stick together.
Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing this pheneomenon, known as the Casimir force, so that it repels instead of attracts.
Some cool stuff to know - we know the laws of physics are different when things are super small and super big - now we also know that materials exhibit different properties when subjected to extreme temp - either extreme cold or heat. Especially Magnets!
