Laser Tractor Beam Now Possible Wow

wait what?

We once may have thought that tractor beams were only seen in Sci Fi movies, the Star Trek series and comedies like Spaceballs.  Physicists have made an actual tractor beam and here is an excerpt of their discovery:

The groundbreaking tractor beam, made of a hollow laser beam (a laser bright around the edges and hollow in the centre), was able to move particles 0.2 mm in diameter distances up to 20 cm (7.87 in) — around 100 times farther than has been achieved in previous experiments.

“Demonstration of a large scale laser beam like this is a kind of holy grail for laser physicists,” said Professor Wieslaw Krolikowski from the Research School of Physics and Engineering at The Australian National University.

Is this insane or what?  What types of applications do you think they will use this if it gets traction 😉 (no pun intended)

Would this be mainly used for…space applications or other things like transportation here on planet Earth?

    Tractor beam? Oh my God. Tractor beams. Wow, what will they think of next? Lasers. Lasers are crap. Just like magnets are crap. Anyhow, love it. Lasers aren’t blowing us up. They are sucking us up.
