Negative radiation pressure in light could make some tractor beams real, we're already sucked in

Developing an actual, working tractor beam has consistently been a physical exercise in defeat: it typically relies on brute force efforts to cause a magnetic link or an air pressure gap, either of which falls a bit short of science fiction-level beauty. The Technion-Israel Institute of Innovation’s Mordechai Segev has a theory that would use the subtler (though not totally movie-like) concept of unfavorable radiation pressure in light to move objects. By making use of materials that have an adverse refraction index, where the light photons and their general wave design move in contrary directions, Segev wishes to develop a sweet spot where negative radiation pressure exists and an object caught in the center can be pushed around. His early technique would make use of very thin crystals stacked in layers to influence the refraction. As it’s theorized, the modern technology will not be pulling in the Millennium Falcon anytime quickly– the millimeters-wide layer intervals dictate the dimension of exactly what can easily be pulled. Nevertheless, also the surgery-level tractor beams that Segev hopes will eventually derive from upcoming tests would certainly bring us a great deal better to the future that we’ve always wanted.
