Cool, but no matter, no sound... which is energy waves moving through matter... *as has been said ...but its the net...EVERYTHING has been said. So no pullee in spacey.
And as far as the tech in Star Trek, yeah, there was that episode referenced, but the big dish on the lower front that looks like RADAR was supposed to be a "repulsar/tractor beam" to scatter debris from their path... so it could move stuff away or pull stuff in.
Embarrassed to have even more Pwnage... pity me

This is way cool, ATS!!! Scientists in Scotland have created a Tractor Beam! What's probably the most surprising is that Scientists use "Sound" not Light to achieve the "pull" effect of the Tractor Beam.
The Dundee tractor beam is not entirely dissimilar from those in “Star Wars” and “Star Trek,” in that it draws an object toward it without making physical contact. The device works by taking advantage of an acoustic wave’s natural push effect, called radiation pressure. (Photons also exert radiation pressure, which is part of the reason comet tails always point away from the sun.) What the Dundee team was able to demonstrate was an example of negative radiation pressure, otherwise known as pull. According to Christine Démoré, a senior research fellow at the Institute for Medical Science and Technology, at Dundee, and a co-author of the paper, one of the team’s main reasons for staging the experiment was to show how easily it could be done. “It’s a relatively simple concept, but it’s just obscured by complex math,” she told me. “By shaping a beam of energy so that it goes around an object in some way, hitting it in the back, it’s possible to then pull the object instead of push it.”
Wow!............just WOW!! Think of the implications here.....think of what this will do for the tow industry....What does ATS say?
