A Real Tractor Beam

[@robertschlesinger1342]

Excellent video covering some state-of-the-art topics. Prof. Grier provides a link to his home page where the interested viewer may find his relevant papers and patents on the topics discussed. An article (click on the preprinted button) in PRL seemed a good paper to start on the so-called tractor beam science.

AWESOME! Thanks Professor Grier and Cool Worlds!

[@maxcyhicks875]

Super cool and awesome breakthrough.

[@twelge15]

Nice serendipitous discovery!

[@JRis44]

love this stuff. wish i were a doctor of the sciences. Maybe one day, then i can get into some of this KOOL research!

[@CoolWorldsLab]

What piece of Star Trek technology do you think we'll crack next?

[@fundingles7645]

Warp drive!!!! I know nasa was messing around with it. How long till the first warp drive space craft?

[@insu_na]

It's fascinating that Star Trek, the show which took the most liberties and was scientifically most inaccurate/implausible, is the show which had the best "predictions" about actual technological advancements... Maybe that is because the show just ran for so long and thus had a lot of runtime to gather ideas, but still... I wish someone who knows SciFi shows and films better than me would compile a list for such things

[@eternallegacy89]

Cool Worlds wormhole generators, idk if Star Trek had those but give it some real thought and it's not all that hard to make actually.

[@andrewreynolds912]

@fundingles7645 irl like almost 2 years ago scientists released papers ohlf a massive breakthrough which makes the warp drive possible!!!!!

[@andrewreynolds912]

@uploadpro irl almost two years ago their was a breakthrough from two articles released that the warp drive is more possible than before

[@andrewreynolds912]

Well freaken done guys!!!!! This is such a good discovery I knew their were possible and did exist etc I hope you guys don't mind me using this for my series for mining, drawing in ships, etc and giving you guys credit as well

[@silvernewman47]

This is really cool!

[@cornbreadhead7197]

I'm watching this in March 9th 2020 7:55am.

[@leemurray5125]

Any possibility of a extended or more in-depth version of this? Forgive me if these questions are obvious, I have no scientific background at all, just a lot of interest and wonder... Is it a case of the hologram is used to reflect the photon momentum? Or is it that the 'cork screw' design pulls particles backwards while moving forward, and if so, how is that possible with light being both a wave and a particle?

[@operation6604]

U failed lmao

[@nuance9000]

What's the diameter of the beam? And are the tractor beams harmful to organic material?

[@CoolWorldsLab]

Beam widths are currently very small, not sure but I think we're talking mm or smaller. These are not harmful beams, unless at extremely high power when, just like any radiation, it wouldn't be great for you!

[@michaelobrien2472]

The diameter of the beam is around 1-10 micrometers, and the beams are not harmful to organic material. Surprisingly, the wavelength of the beam determines whether it is harmful. In this case, the beam wavelength is in the infrared range. Unlike harmful UV or even gamma radiation, organic material does not absorb infrared light and we are surrounded by it all the time.

[@shannonbentley9935]

i think you need to take a look at antione priore's work a french man who was able to manipulate cells in the human body think of the cells as atoms, or small magnets... he used radio waves to penetrate the body, a resonant sound via a frequency to match the cells frequency, causing the near field effect in the cell virtually disabling it , or causing it to behave like a black hole , sucking in photons to gain energy and correct the wobble in a sick cell, i believe the same can be accomplished, by using a pair of lasers with a variable frequency that would be controlled by computer to quickly rise through a huge range of frequencies until a resonant frequency is met, causing the near field effect, it could also be 180% opposite of the resonant frequency as this is the key to so many things in science

[@kingjames-fn8ib]

make light spin in a helix formation?Photons travel in waves .Maybe high intensity ,extreme low frequency radio waves. Or in other words condensed low frequency photon burst

[@shannonbentley9935]

question have you considered the photo electric effect, maybe a blue light is preferably better than the red light?

[@kennethhicks2113]

How's the project going?

[@worldbestt-shirtshoodie-go6184]

Shared on @dreamcatcherdesign2020 - great job ;) can you share the details for all to see or even help you to ro it?

[@maxcyhicks875]

Like an Archimedes screw? Project will probably get further with Space X.

[@CodeLeeCarter]

We need SUBSPACE Communications.

[@PressHBCA]

Aircraft carrier tract beam push pull technology which Slows the aircrafts on final approach by aft mounted blowers while electromagnetic coils pull the aircraft not on the flight deck but into the interior of the ship then land it on to conveyor were crew can immediately inspect , refuel and return via hangar elevator for relaunch with in 30 minutes. 2032

[@habibaghasafari2237]

are EM drives can really break third newton law and produce thrust without any reaction force?

[@CoolWorldsLab]

Current consensus is that they don't work, reported forces are at the level of experimental errors.

[@scottypimpin4257]

"You may say so what" What!! That's not what I said at all. Imagine the possibilities. Forget about getting smashed by asteroids. Forgetta bout it!

[@TeethToothman]

☕🦐☕

[@shannonbentley9935]

try magnetizing a piece of metal from a distance.....

[@2013wearestillhere]

Can a laser produce and project a magnetic field? Can a strong magnetic field be projected from space to Earth, to pick up a object, or payload, and pull it into space?

[@shannonbentley9935]

why not try forming a torus beam this is the most effective

[@GyanPrakash]

I'm wondering who the Fuck is that one Disliker 😎

[@CoolWorldsLab]

Some men just want to watch the world burn

[@GyanPrakash]

@@CoolWorldsLab❤️❤️🙏

[@xevious2501]

one problem with this idea. Lets say you have a powerful fully functional tractor beam on your spacecraft. And lets say your attempting to capture and haul in a floating asteroid. Your space craft is weightless in the vacuum of space if not in motion and the only weight momentarily achieved is when mass opposes one another. in other words.. using a tractor beam only works if you propel the capturing spacecraft away from the object your trying to pull in, Or your mass must be considerably greater than what your attempting to pull in. or another way to thing of it... Your doing a space walk, you have a grappling hook and chain which represents your tractor beam. theirs an asteroid slowly drifting by.. you shoot and connect your line to the asteroid. do you have the asteroid or does the asteroid now have you? First you need an apposing force to stop it. then you need a means to anchor ones self to pull it in. In the case of a light beam, its really no different than a physical chain. But for a second lets say it is different, that despite the craft projecting the beam it doesn't effect the beams source at all, it just moved whatever the light strikes, well.. if thats the case, wouldn't such a beam also solve our problem with propulsion? you'd just aim the beam at your own craft which effectively makes it a lightwave engine.

[@zka77]

wtf he never blinks

[@thesqweebliest3727]

Lmaoooo “tractor beam” what a joke. I get that later he suggested using the gravity of the asteroid to adjust its course, but him bringing up sci-fi garbage was funny. Im adding this here cuz i decided to look up recent breakthroughs before posting this message, and aparently they made a “tractor beam” in 2023. Def doesnt seem like it could pull an asteroid but sci-fi garbage isnt right either (allegedly). Still tho its kinda funny
