Posted August 20, 200520 yr http://www.eurekalert.org/pub_releases/2005-08/epfd-ltt081905.php So much for what we thought we knew about our universe. Now how do I get my brain signals this fast when I am playing online games.
August 20, 200520 yr a couple years ago they slowed light down to something like 35mph. I think you can also use Bose Einstein Condensates to "trap" light (BOE's are the 5th state of matter i think, a kind of super atom). I might be wrong, Ky is the most qualified to talk about this topic
August 20, 200520 yr Faster than light group velocity and non-violation of relativity? That would be the day... I didnt read the APL article (cant from home), but i trust it. I think the author(s) of the article under the link must have misunderstood something. Faster-than-light phase velocity - sure it can go all the way up to infinity, but group velocity? Thats one hell of a black hole. "Slow down" light - sure. I dont know exact numbers, but as light travels though disspersion body one gets effect of light 'slowing down'. Thats the first time i heard someone call BE Condensate as 5th state of matter. I dont think its called that officially. But its definately NOT called a super atom. That title is reserved for quantum dots. Optical memory is cool. If the effect depicted (minus the faster-than-light something) could be controlled in greater extent, then the optical processor is just a handspan away. And thats where my future work lies (not in THE processors, but maybe in their controllers).
August 20, 200520 yr I saw Atma running one time in FA and he actually stopped light from moving. Believe it or not!
August 20, 200520 yr It isnt really faster than light, if it is light. Then they would be the same. did you just tell scientist they are wrong? a few years ago they proved that it can be slowed down by freezing particles around it, part of the absolute zero and quantum computer projects
August 20, 200520 yr Author Or maybe my brain already goes this fast, which explains why Deadroach can be point blank behind me in CS:S, shoot me in the back, and I can still turn around and kill him before I go down. *poke poke poke*
August 20, 200520 yr Now, lets just expand that optic fibre to the size of a spaceship and we'll be set
August 21, 200520 yr He said "faster". as proven with nearly anything else..... slowing down by freezing can increase speed by increasing heat, or energy. sorry i guess i took basic chemistry for granted
August 21, 200520 yr slowing down by freezing can increase speed by increasing heat, or energy. ........ .... .... .... .... DECIPHERING FAILED return 1;
August 21, 200520 yr .... .... .... .... .... .... DECIPHERING FAILED return 1; are you serious? when particles are cooled it slows them down (rememebr the direct corralation between heat and energy) when heat(energy) is addd they are excited and speed up intheir collisions and velocity.
August 21, 200520 yr You can see who are the nerds out here lol:P j/ k it sounds cool, can you imagine the dload speeds in the future oh man, dloading dvds in a second, no lag on bf2 sweeeet
August 21, 200520 yr slowing down by freezing can increase speed by increasing heat, or energy. if that really is just one sentence, then I took basic grammar for granted. Grammar and syntax are important, and that includes punctuation. If you fail at communicating your ideas properly, it doesn't matter how much you know because no one will understand you.

If you fail at communicating your ideas properly, it doesn't matter how much you know because no one will understand you. This is why i said DECIPHERING FAILED Also, the 'explanation' post is strange, for it suggests, that light can freeze the same way as particles... which i dont think is the case. Speed of light in vacuum (where, according to the standard definition of temperature as an average kinetic energy of the particles, we have 0K) is set and, i believe, derived from first principles using methods of quatum electrodynamics (which i didnt have a pleasure to study, but not all is lost yet). Its the interaction that light has with solids and liquids and gasses that gives us all those wonderfull effects.Speed of light cannot be higher than the speed of light (when considered as a group velocity of propagating wave packet), for it would suggest that 'some parts' of our universe are (considering a moment in time on the time-space plane) in the future. Maybe this thing happens magically in those magic balls sharlatans use to get money from people, but physics is reluctant to believe in this. There is also one more, shall we say technical, aspect of this. This effect would couse cathastrophic breakdown of our space-time plane destroying all symmetry and physics with it - not to mention ending space and time and us with it. PS. "Direct correlation between heat and energy" is that its THE SAME THING. Heat is the thermal part of the energy called differently for names sake.

August 22, 200520 yr Well, I guess there are those who hide in the shadows and wait for someone to say something they didn't know. Then, they attack them for speaking in a syntax that online gamers use and understand. In the sense of lacking grammar, punctuation, and full sentences and words. It's still nice to know that not all of America, or the world for that matter have gone down the hole and lost any sense of correct communication. Thanks Haya
August 22, 200520 yr PS. "Direct correlation between heat and energy" is that its THE SAME THING. Heat is the thermal part of the energy called differently for names sake. righto, the rest of it is your standard set of rule when looking at matter. However, the question still remains, is light a particle or a wave? The debate continues. A lab in the Midwest attempting to reach absolute zero noticed they can also slow down light. What is light? (Electromagnetic radiation of any wavelength) the color spectrum is a great example of the speeds. While some are noticeable and some are not, the various wavelengths are such because they travel at a different frequency. The speed of light in the STP (standard temperature and pressure) conditions will mostly remain constant. However, in computers and other imperfect conditions, the speed of light is actually slowed down, do to fiber channeling. The reason there are different levels of fiber optics (not to mention pipe size) A little history for our readers: http://www.colorado.edu/physics/2000/bec/temperature.html http://news.bbc.co.uk/1/hi/sci/tech/254305.stm time for work
August 22, 200520 yr eh, isn't light a wave? cuz how can particles travel trough lets say fiberwire? you can't move particles trough something solid can you?
