The wonders of science and technology.. That optical illusion brought about by deflection of light making something invisible to the eye is amazing just like in Harry Potter movies. Thumbs up to the physicists!
Invisible gateways, like the one in Harry Potter, are a step closer to reality, thanks to a new theory developed by scientists.
With the help of a technique known as transformation optics, the research team from Hong Kong University and Fudan University in Shanghai has found a way to alter the pathway of light waves that could eventually allow them to develop portals that are invisible to the human eye, reports The Telegraph.
