Star wars holograms
Science fiction is sometimes inspiring the scientific advances of future times. If today we are greeting the arrival of video calls, Japanese scientists from the University of Tokyo are already investigating how to make it possible to send three-dimensional holograms in true style Star wars. At the moment they have achieved it in laboratory practices, on a scale of 20 centimeters in diameter and 25 centimeters in height. Of course, the production costs of one of the cylinders used is close to $ 100,000, although the Japanese inventors, Susumu Tachi and Tomohiro Endo, expect them to drop a lot if they are produced in a massive way. May the force be with you.
