Scientists Build Working Tractor Beam, Although It's Comically Tiny

, a team of scientists figured out how to build a new laser that can form an optical tractor beam capable of manipulating objects at a distance.

"In previous studies, the light pulling force was too small to pull a macroscopical object," said research team member Lei Wang from QingDao University of Science and Technology in China, in"With our new approach, the light-pulling force has a much larger amplitude," he added. "In fact, it is more than three orders of magnitudes larger than the light pressure used to drive a solar sail, which uses the momentum of photons to exert a small pushing force.

"Our technique provides a non-contact and long-distance pulling approach, which may be useful for various scientific experiments," Wang said in the statement.According to the researcher, it may prove especially useful in some unexpected places as well.

As AI will make people jobless many will be offered jobs on Mars You have to pay half million for one way ticket to Musk No money you will work for free/pay in installments Some like me would be merged with machines to dig for olygarchs As they say 'all this to benefit mankind'

I don't follow Mars rover much - they abuse me for so many projects I cannot keep track But based on recordings it seems that is around river Sava Rover is complaing (yes it has voice) that is unwell and that her head hurts but SenBillNelson wants to break records Make history
