Tractor beams are real

Erm, just saw this browsing some forums and remembered the geeky stuff here, so here it goes

Well quite frankly we had tractors and they project beams (the headlights) so you are very late with this I feel.

Jokes aside i heard about this from sci-show a year back,however i remember it used spiraling particles inside a laser beam but i cant be sure, I dont really remember.

They planned to use it with probes to scoop up material from comet tails,among other uses.

Apparently some US and UK physicists figured out how to develop an acoustic tractor beam
