Future Watch:

Harry Potter-like invisibility cloaks could become a reality a lot sooner than you can imagine.

According to a recent National Geographic report , researchers have managed to find a way of bending the geometry of space so that light from all directions travels around an object. Now, you might be fairly aware as to what happens when light does not hit an object. It turns invisible!

Even in 2005, an invisibility cloak was pure science-fiction material. It was after an increased amount of interest in this field that the current advances have been made. While the science behind the bending of light is definitely not something new, it sure needs a lot of tweaking before us humans can effectively use it to make an object invisible.

All an invisibility cloak needs to do is to bend the light in a more sophisticated way than it is currently possible. However, reaching that kind of sophistication levels needs hard-core research.

Ulf Leonhardt, a visiting professor at the National University of Singapore, says that it's a question of the will and the money put into this field that will decide how soon you would see invisibility cloaks for sale on Ebay. At the same time, he does add that invisibility cloaks are feasible now .

That sure is a huge departure from the position in 2005 when this was all Star Trek stuff!
