In space, blackholes are collapsed stars whose entire mass is condensed into a minute volume, creating a gravitational well in space known as a singularity. Or in layman’s parlance, it sucks everything in and never lets it out. Purdue researchers Evgenii Narimanov and Alexander Kildishev published a paper describing a method to construct a tabletop device with blackhole-like properties to bend and pull light inward. While not for visible light, Chinese developers Tie Jun Cui and Qiang Cheng have constructed the device for microwaves and ambitiously anticipate constructing a version capable of absorbing all optical light by the end of the year.
