Yup, a working tractor beam has finally been made. It only moves almost microscopic particles at this point, but it's a start! Imagine the possibilities in a few decades.



here's the abstract:

Yeah small particles, but the amount of energy to move something large with light is crazy. Cool idea but not really practical in terms of moving objects

so because of the properties of light, it can cause an area of low pressure and lift towards it like a plane wing? and they get it to go up by creating these forces equally on both sides (they used to beams)?

Not an area, but individual particles by hitting them with high energy photons i.e. gamma rays.

Listen to this guy. He's taking physic classes in a university, so he must be really smart.
