Effect producing laser

I've just noticed this link - I was WTF at first glance, but after reading paragraph or two it was clear what they are talking about. I call it "science tabloids". However it is just seemingly breaking relativity - no information is carried with this higher speed. It is just mentioned there as well. It is similar like you might shine laser on very distant wall and move really fast by rotation -the dot on wall might also be faster than speed of light, but does not carry any information from place A (first hit on the wall) to B (the last hit on the wall).

Also there were some doubts that they measured neutrinos (?) faster than light (in vacuum!!!) recently, but it was proven to be a problem in some cable or something like that, if I remember it correctly.

Another interesting effect is in nuclear reactors - cherenkov radiation - also caused by particles faster than light (but in that particular environment of course). It looks like this:

Oh yes, I was by far not suggesting that the information was being transmitted FTL, but it sure was an interesting article. Neutrinos was a measurement error and haven't been proven to be FTL. I have heard of Cherenkov radiation but have no knowledge on it. Thanks for sharing Radim. :)
 





@Accutronitis: OMG, that is something Thor would be proud of. :D This laser is a serious fire hazard. And it is a very nice sound effect demonstration for OP.

I think I'll go to see some industrial lasers in some of our companies in holding I work for. I guess there will be also nice cutting sound, but not sure how to record it as there are likely cooling, technical gases and other noises during operation. What I've heard some new lasers are being bought, so that would be nice opportunity for an inspection. Shame on me I did not do it already. :D

@Oliver: Yes, I'm sure with that. BTW when I was a kid I wanted to build a reactor, luckilly I could not find any radioactive material to be used. :D These child games were awesome...
 
Burning something underwater with any laser that can burn produces a sound too!

ED: I tried it on a piece of plastic in a glass.

Good point!

BTW:

I would be interested to see some extreme power IR laser vs. water. :D

I didn't see anything, What happened ? Was that the laser making the sound or was it the water ?

Are there any lasers that make effects happen? Heating things up will not count. My question is about lasers that can move objects or make sound or any other interesting effect.(eg. open portals, or cooling objects)

Open portals?

But more than that a laser that builds elements using photon particles is what i am interested in. Possibly a water producing laser.

If the tech doesn't exist there is likely something useful to be had.

What useful laser applications have we not invented?

A water producing laser? It is called a garden hose.

What inventions have not been invented? :crackup:

I smell a troll, also.

Go back to your video game world of make believe.

Thanks Accutronitis. :beer:
I'm glad to say that was the first time I've been spoken to like that on here. Everyone else is so friendly and respectful.
 
What I really like on this forum is that "small minded" people here might have a nice discussion initiated by kind of these troll-like questions. :D I personally found some nice links and printed one article to read later. I think this is what counts. Why not to turn all troll attempts to this as defence against them?

Be careful, he might open up a wormhole, a very backdoor to another dimension, controlled by other worldly forces! You can be sucked in and transported wherever! :drunk:

This is so true. We should just twist troll posts around for our own liking. That will annoy them. I wanted to rep you a few times today Radim, but I've got to spread some around. :beer:
 
Do not worry, Oliver. The same here. I noticed that in most cases I want rep someone I cannot as I need to spread more. :D
