Researchers from Brown University and Delft University of Technology in the Netherlands have developed an ultra-thin, ultra-reflective membrane designed to ride a column of laser light to incredible speeds.

The surface is intricately patterned with billions of nanoscale holes, which help to reduce the material's weight and increase its reflectivity, giving it more acceleration potential.

The research is a significant step toward realizing goals like those of the Starshot Breakthrough Initiative .
