British Engineers Create Sonic Tractor Beam (bbc.co.uk)
An anonymous reader writes: According to the BBC, engineers in Bristol, England have created a system for remote manipulation of physical objects using sound holograms. The video shows pea-sized objects being dragged around and stacked up in mid-air with no visible means of support. "In essence, an object sitting in a 'quiet' region of space can be held there if it is surrounded by very high-intensity sound waves. As the pattern of that boundary shifts, the object can be moved around." If the Empire is making a tractor beam, now they only need a Death Star to go with it.
When will they get this in screwdriver form?
A tractor beam, that relies on waves propagating through matter, that will work in the nearly matterless void that is space, right?
Just turn up the volume until it works..

It attracts defense $.
You might even call it a "contractor beam."
In Space, no one can hear you tractor beam.
That's so right!
Its because of all those other galaxies. Andromeda, Cartwheel Galaxy, NGC 4676. They are ripping us off. They make a fortune with our air. If Trump becomes president, he will bring back the oxygen, he will bring back the nitrogen, and make this galaxy GREAT AGAIN. He loves the Cartwheelians. He loves the Cartwheel people. He has thousands and thousands working for them. Their leaders are too smart for us. Imagine Rubio negotiating with the Andromedans about the merger. Whom do you rather want to negotiate with them: Rubio or Trump?
You see all these asteroids entering the atmosphere? Killing the dinosaurs? Gertie! Gertie, oh wonderful Gertie! Killed by an asteroid. Five times it has already passed earth, five times it has been coming back. With the solar system filled with air, all the asteroids will burn. Yes burn. Trump knows that's not politically correct, but one has to say how it is. Do you want somebody with low energy to be president?
Yesterday, polls came out. All arms for trump. The Sagittarius Arm. Leading by ten percent. The Scutum Arm. 30 percent. 30. 30 percent, the second has 2, can you believe it? The perseus arm. 40 percent. In one arm, trump fell back. By two percent! The next day, the whole press titled "TRUMP FALLS BACK". Can you believe it? Unbelievable. If he didn't fall back, it wouldn't be worth a line for them. They are all liars. Not all of them, but 70 percent of them.
Trump will make the milky way great again.
