Quote from source:

In July engineers demonstrated that beams of light can be made to repel each other, much like repulsive electric charges. The discovery could help control data transfer through the Internet and enable cell phones to work more quickly while drawing less power.

The findings from Yale University electrical engineer Hong Tang and his team build on discoveries they announced in late 2008, in which they demonstrated the opposite effect: attraction between light beams confined within a silicon chip. Together, the attraction and repulsion effects make up what is known as the “optical force,” a phenomenon that theorists first predicted in 2005. The force acts along an axis perpendicular to the direction in which light is traveling. Parallel beams can therefore be induced to converge or diverge.





Another interesting breakthrough. When we are able to understand and harness the power of light things will change for us, and hopefully for the better. It is interesting to see the amount of breakthroughs that have just happened or that are going to happen in the near future. Hopefully humanity found it's place to advance.

Any thoughts?

Pretty cool stuff. Any uses for it?

The post clearly states that this phenomenon could be used to increase performance of mobile phones and control data transfer through the internet.

One would expect more uses to be found in the future as it seems to be a recent discovery.

I think the phenomenon itself is the interesting part.

Light research is very fascinating to me especially since it's proven that our brains use photons as part of its current when processing sensory energy into the rendering of our perception.

Light as an information system is quite amazing, from DVD's to holograms to every day visual perception. It's a data system unlike no other.

NO : THE SOLUTION IN NOT AN ANOTHER F* STUPID TECHNOLOGY.

We need an other society, we need a better society.

Could this discovery that light particles repel/attract lead the development of a "Photon Drive" type engine or power source?

Or could this research be expanded to enable us to use Starlight to pull or push a craft in space?

Intersting discovery!

Have you ever used technology in your lifetime?

Then STFU. thx.

Personally I don't think technology is the downfall of our society. Substandard parenting and lack of accountability not to mention frivolous lawsuits and a "world revolves around me" persona is the downfall of our society.

Technology didn't make us lazy it just gave our lazy a``es something to do.

NO. STFU.

Our society is the worst you can imagine : the world change : not our society, not our way of living together : if you cannot see where comes the problem in our society (stfu).

I just tell you one more time : the illusion that progress will save human being have been use for 200 years : what I see : nothing : nothing changed in the system. Because the technology is not the solution : it is far from the real problem !

Where come the problem of violence ( so the so called insecurity , and "terrorist" in our society) : from proverty : where comes proverty in our rich country : from the capitalism , and the infinite accumulation for SOME ( this is their rules: the little fish is bigger and bigger : and bigger than a democratic state , and bigger than the power of individuals)

because 0. A cast society where the "money" rules the world (read plato, proudhon and marx) 1. NO real freedom : you have to work to get money in order to live : and TODAY WORK is not WORKING AT SOMETHING (read The Origins of Totalitarianism, Hannah Arendt.)2. No real way to live for 50 millions people in usa ( they have to find other way : this is prooved in sociology )

SO STFU if you have never think about it with a critical and opened mind !

If you just don't understand that the problem the system : the dispatching of ressources you are blind !

What is with the self-righteous outrage hijacking threads lately? Don't like the way the world is? then go do something about it, instead of posting on a forum and ruining other peoples' good times.

I can't believe humans are just now figuring this out, when it has been known for a long time.

Light is electromagnetic. The entire electromagnetic spectrum is light. Radio waves, microwaves, IR, visible light, UV, X ray, Gama ray, all of it is light.... all of it electromagnetic.

Since the invention of radio it has been known that Sunlight effects radio waves, so at night you get a better reception. Sunlight and radio waves are both light, and they are both electromagnetic, and they interact with each other meaning a repulsion and or attraction which causes bad reception.

That is the real reason for color. An apple is red because the electromagnetic atoms of the apple are repelling the red electromagnetic light, and attracting the rest of the electromagnetic light. A white t-shirt is repelling all light, and a black t-shirt is attracting all light.



....matter is compressed light.

Rings of light..............................

Imagine light attracted to itself in a circle, like a dog chasing its tail.

If it can be used for military purposes or cannot be adequately taxed or sold to the populous, it will most likely be stifled as long as possible until that prerequisite could be met.

Light needs a 'carrier ' as such. Light is slow in reaction and reabsorbtion compared to the host carrier. Frequency related speculation is fun isn't it?

Maybe science needs to examine the fundamentals, just maybe they will uncover some truth.

Matter of fact: light is an unrecognised element that requires admittance to Earths periodic table.

Nice rant. World not set up to suit your taste, eh?

Well, this is the Science and Technology Forum. Here we are not interested in wild imprecations against whoever it is somebody happens to hate. If you think scientific and technological advance is bad for humanity, why are you on this forum? Try the Philosophy forum, or Above Politics, or Below Top Secret where you can parade your dissatisfaction to your heart's content and find any number of sympathetic souls.
