Atomic chamber in which tractor beams were created.

Rather than sucking space ships into a space-station, a tractor beam created by University of Adelaide researcher Ashby Hilton and his colleagues pulls atoms into a microscopic hole at the center of a special optical fiber.
“Although tractor beams are green or blue in the movies, in this case the trap is made of invisible infrared light,” Hilton said.
“The beam grabs hold of atoms that are floating in a chamber that is almost completely emptied of gas — a little sample of outer space on Earth.”
“Every atom that enters the tractor beam is pulled into the fiber — there is no escape. And once sucked into the interior of the optical fiber the atoms can be held for long periods of time.”
“Our experiments show that we can very precisely control light to produce exactly the right conditions to control atoms.”
The tractor beam works by the infrared light interacting with the atoms to create a change in energy which drives the atoms to the most intense part of the light beam.
“What is really exciting is that now we have the possibility to do quantum experiments on these trapped atoms,” said senior author Dr. Philip Light, also from the University of Adelaide.
“Our first experiments intend to use these stored atoms as elements of a quantum memory. We hope that our work may eventually form part of absolutely secure communications channel that is of obvious high interest to defense, intelligence and industry.”
The team is now moving onto the next stage in which the tractor beam is formed from a hollow cone of light rather than a solid beam of light. In this new configuration the atoms will be held at the center of the light cone where it is perfectly dark.

I’ve always wanted a Tractor Beam.
When will Amazon be selling them?
“which drives the atoms to the most intense part...”
Drives them or pulls them?
Is it an Allis chalmers or John Deere tractor beam?
“Although tractor beams are green or blue in the movies, in this case the trap is made of invisible infrared light,” Hilton said.
So if your space ship is near an alien space station and you see nothing, go to red alert.

This technology came from Nancy Pelosi’ plastic surgeon.
I’ve always wanted a Tractor Beam.
When will Amazon be selling them?
—
Amazon will have them, but they’ll be in lots of a dozen, but with Prime 2-day shipping.
What about Tractaters?
What is that?
Lol! Pretty good.
Doctor Who reference I think.
Isn’t there a song “She thinks my tractor beam’s sexy”?
No, probably not.
Not possible as long as their are liberal democrats in the world.
