[email protected] Abstract:- Scientists have designed a way to levitate and propel objects using only light, which means objects of many different shapes and from micrometers to meters could be manipulated with a tight beam. With the new research, published in the journal “ Nature photonics”. The key is to create specific nanoscale patterns on an object‟s surface. This paltering interacts with light in such a way that the object can right it self when perturbed,creating a restoring torque to keep in the light beam.Thus,rather than requiring highly focussed laser beams,the object‟s patterning is designed to „encode ‟their own stability .The light source can also be millions of miles away.Atwater said “ There is an audaciously interesting applications to use this technique as a means for propulsion of a new generation of spacecraft.We were a long way from actually doing that,but we are in the process of testing out the principles”.

Introduction:- Scientists have designed a way to levitate and propel object‟s using only light, by creating nanoscale patterns on the object‟s surfaces. Though still theoritical,the work is a step toward developing a spacecraft that could reach the nearest planet outside of our solar system in 20 years,powered and accelerated only by light.This means no fuel needed,just a powerful laser fired at a spacecraft from back on Earth.
