'molecules' made of light

[jos]

It's not lightsaber time, not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings hint that weightless particles of light can be joined into a sort of "molecule" with its own peculiar force.  We're learning how to build complex states of light that, in turn, can be built into more complex objects. This is the first time anyone has shown how to bind two photons a finite distance apart. 

 engineers need a way to precisely calibrate light sensors, and Gorshkov says the findings could make it far easier to create a "standard candle" that shines a precise number of photons at a detector. Perhaps more significant to industry, binding and entangling photons could allow computers to use photons as information processors, a job that electronic switches in your computer do today.

 

 

Hope it wont be something that will never see the day of light

liking this because of the subject matter. no pun intended. 

[Trik'Stari]

When can we have holograms?

 

please?

[deviant88]

Light beam guns yes, lightsabers are overrated 

[Briggsy]

Pretty cool. At the rate technology is advancing, this should be a thing before dinnertime.

[Doobeedoo]

Nice. Always awesome to see tech based on light.

Idk if the materials are made of photons themselves, but technically everything is composed of energy. Photons (light and other electromagnetic waves) being one of them, baryons (most matter, but not electrons) being another.

It's one thing to bind 2 photons together, it's another thing entirely to get photons to stop moving around at the speed of light.

Light isn't matter.

Its been done before. They have stopped light in a crystal for a fraction of a second before.

Light isn't matter.

if light is both particle and a wave, isn't particle a matter ?

No, light is an energy. Matter is something that has mass, and takes up space. Light does neither.

still can't understand how shadow has a mass but not the light.

Would like to see the link to that article. Or this is a seriously misrepresented case of light refraction.

 

On the other hand, the light would have to convert itself into another form of energy. I wouldn't know which form though (excluding electron excitation/kinetic energy - that's how colour and refraction works) and how it would fit back into the crystal. It would then rapidly decay back into photons and continue its business..

I was wrong. It was a full minute. http://www.dailymail.co.uk/news/article-2380028/Scientists-stop-light-completely-record-breaking-MINUTE-trapping-inside-crystal.html

A shadow doesn't have mass. A shadow is the abscence of light. Shadows aren't matter either.

Your argument is moot.

 

(sorry my brain is fried i cant speak about the science of this now, but feel free to mention me if you dont get anyhting and ill come back later)

Awesome! and eventually it will be lightsaber time.

Im aware of that video. I figured that's what you were referencing as well. Weight and mass are different. Mass is the amount if matter. Shadows aren't matter. However, light does have a very very minuscule amount if force. The lack of light means shadows would make you weigh "less" than if there were not shadow. Please pay attention to the video. No where does it say shadows have mass.

I don't like how he is saying light "pushes a little bit" on things to make stuff happen. It doesn't.

 

It causes/forces electrons to be ejected from the surface light comes in contact with. Although NOT always like in the case of the light not being above the threshold of required energy to make the electrons fly off the surface of whatever the light is hitting. So technically however many electrons are removed from the surface would indicate a mass reduction of that surface material. If anything it would weigh less!

thanks for the response, i was just trying to prove my interpretation of pun was right. and yeah, i know light does not have matter, most of the people wont go further with this topic, unless they do like you did.

[Guest Strangerbob]

molecules cannot be made out of mass-less particles such as light

 

furthermore mass-less particles 100% of the time move and move at the mathematical speed limit of the universe, or "speed of light"

[deviant88]

Your argument is moot.

Unless you also have 'the force' with you lightsabers are useless.And stop acting like a kid. Weapons are used for killing, usually in war, there is no elegancy in war.Obi-wanker or not.
