“Star Trek”-like tractor beams may soon be a reality now that researchers have harnessed the ability to move objects using the power of sound waves.
“We were able to show that you could exert sufficient force on an object around 1 centimeter (about 0.4 inches) in size to hold or move it, by directing twin beams of energy from the ultrasound array towards the back of the object,” said Dundee University physicist Dr. Christine Demore of the university’s Institute For Medical Science and Technology (IMSAT), according to The Daily Mail.
“This is the first time anyone has demonstrated a working acoustic tractor beam and the first time such a beam has been used to move anything bigger than microscopic targets,” she continued.
