View Full Version : Fater than the spped of light??
daveyjones 11-09-05, 04:35 AM Hi,
I read that using Plasmas, the phase velocity of an em wave can be increased instead of decreased as in normal materials.

Does this mean that you could send data faster than the speed of light? Or does this defy special relativity?
Cheers,

one_raven 11-10-05, 05:05 AM I'm fatter than the speed of light, but that's because I tend to move relatively slowly as I get older.
By the way, "fatter" is spelled with TWO t's.
weed_eater_guy 11-15-05, 10:13 PM i havn't the slightest, you can't send material faster than the speed of light, but i don't think there's anything saying you can't send an effect faster than the speed of light. i.e, electrons move in a wire at only about 22mph (i think), but the "electricity" they transmit goes at light speed. alot like marbles on a groove, knock one marble on the end and the other end moves almost instantaneous. who knows, maybe we CAN make an effect go faster than light, thus FTL telecommunications? nice idea...
Perhaps "fatter" is spelled with TWO t's, but is sped speeled with TWO p's?
Your typos are certainly faster than light. ;P No offense, of course.
Anyway, light speed is the limit. You can't go faster, but you might be able to bypass it.

c7ityi_ 11-20-05, 12:17 PM Magnetic waves go with infinite speed so it's impossible to go faster than them. But it's pretty easy to go faster than 186000mph. Infact, we're already travelling faster than that. Speed is an illusion. To an observer, the speed of light is 186000mph but if you speed yourself to the speed of light, you go with infinite speed.
Actually, when you get right down to it, the speed of light is considered to be ( pretty much ) 186,000 miles per SECOND.
tucandan 11-21-05, 03:40 AM Actually, when you get right down to it, the speed of light is considered to be ( pretty much ) 186,000 miles per SECOND.
The speed of light actually changes based on where you are in the Universe, for instance, light speeds up as it bends around the gravity well of a star, or accelerates as it spirals into a black hole. With a variable for a limit, I'm sure we'll be able to surpass the speed of light someday.
c7ityi_ 11-21-05, 06:07 AM Actually, when you get right down to it, the speed of light is considered to be ( pretty much ) 186,000 miles per SECOND.
Yes, if an observer observes the light, but if an observer travels at the speed of light, it is different.
According to ideas about tachyons, they only ever travel faster than light, never slower.
guthrie 11-25-05, 04:17 PM But I dont recall anyone taking tachyons seriously since the 70's or suchlike.
Actually, when you get right down to it, the speed of light is considered to be ( pretty much ) 186,000 miles per SECOND.
But I thought light had no time to travel so it cannot have speed even thought it has so much speed that it makes everything --with time -- stationary and thus timeless.
Where did my BSc in physics go wrong?

"...Magnetic waves go with infinite speed..."
Not true.
"The speed of light actually changes based on where you are in the Universe, for instance, light speeds up as it bends around the gravity well of a star, or accelerates as it spirals into a black hole. With a variable for a limit,"
Not true.
"Yes, if an observer observes the light, but if an observer travels at the speed of light, it is different. "
Not true.
Have *any* of you ever cracked a book on basic physics? (Or are y'all just pulling my chain?)
Anomalous 12-22-05, 11:00 AM I am amazed and astonished at the ignorance permeating this thread.

Not true...
Not True ?
dude, light is a EM wave, at speed of light the E and M of light are not affected, had they been then we would have seen those effects on light at light speed when compared to less than light speed light waves.
guthrie 12-22-05, 03:56 PM Pardon? Infinite speed is not the same as the known and measured velocity of light.
Mosheh Thezion 12-22-05, 08:08 PM There is only one thing that can, without any doubt, move faster than light...
and that is an electric field .. or line of force...
T=CR.... it is not limited to light speed.

Euler is my Hero 12-26-05, 01:30 AM DaveC4,
I'm not saying that I disagree with you, but could you give a little support to your claims? Actually, same for you, Mosheh and Anomalous.
Mosheh Thezion 12-26-05, 01:35 AM T=CR... if we have a potential of say, 1 Mega-gigavolt.. and the resistance is low..
and if the overall capacity involved is low... say 1-2 lines of force..
then the timing constant shows that an electric field can form, literally across the entire universe... virtually instantly...
This is not commonly known... since many simply dont understand, and fewer still care....

BeavisAndButthead 12-26-05, 04:50 AM Traveling faster than the speed of light is not possible. Since light composes everything you see, there is a physical barrier (mass in itself) when you reach speeds of 299,792,458 m/s.
IF it were possible to send a person, for example, faster than the speed of light, you wouldnt be able to see that person at his/her actual location, but only at the point where the light travels. If I still didnt get my point across, please tell me as I can expand.
Or does this defy special relativity?
Nay, as the group velocity of the wave is slower than the speed of light in vacuo. Which means that the energy will not transfer at a speed faster than 'c'.
I suppose you could consider a phase velocity to be like a shadow that may appears to move faster than the object which casts it. The velocity of this shadow may appear to be greater than the speed of light.
Just don't quote me on that, my interpretation here could be garbage it seems like a reasonable analogy at this time of night. :p
Does this mean that you could send data faster than the speed of light?
Good question. I can't remember the answer to this as such. I've seen the Guiness Book of records print that music has been transferred at speeds greater than that of light in a vacuum. But, I'm hardly going to quote that as a reliable resouce... much like wikipedia.
The only instances I can recall of articles about faster than light information is anything to do with quantum entanglement (try a search for the EPR paradox).
On the point of magnetic fields:
I do recall the arguments stating that as no Magnetic monopoles exist, their field lines are continuous. If a material is given a bulk magnetic field then presumably the field lines would need to be connected instantly. But, then again people are currently searching for a way to violate this.
then the timing constant shows that an electric field can form, literally across the entire universe... virtually instantly...
Interesting. However, I'm in doubt as to whether the potential from a charge can appear instantly across the otherside of the univese. I was under the impression that measuring the potential of a moving charge was done at a retarded time, whereby the speed of the information of the potential is less than/equal to that of light in vacuo.
I don't consider field lines to be physical which might be my problem?
Mosheh Thezion 12-26-05, 11:48 PM an electrostatic line of force... has no mass... none..
and has no wave aspect like photons...
it is pure one dimensional force...
it is pure energy, in its most fundamental form... and is not limited to the properties of anything with mass.. or even slightly electromagnetic..

This is complete nonsense. Has anyone of you cracked a book on relativity?
Mosheh Thezion 01-03-06, 11:25 PM yeah... umm... NO.... sorry...
everything is not made of photons... as photons are actually made up of two known components.. and oscilating electric field, and the corisponding magnetic field..
so in fact.. while you can say that photons have a mass.. the same cannot be said about an electric field... which is not oscilating...
all speed of light measurements are made using light... and or electrical impulses..
both of which as muti dimensional wave forms of energy are restricted by the spatial flow rate of the Ether.
even an electrical impulse is a wave pattern on an existing field.
the field it self is established, technically.. at both ends at the same time...
and that is why it can be virtually instantaniuos...

Thoes were great points.
I am wondering what must be frequency of a photon wave at full light speed.
daveyjones 01-04-06, 05:09 AM Hi all,
I'm glad to see my post has generated quite a heated debate, even if my spelling is rubbish! :p
I just want to refresh what I was asking as some people have clearly not read the original post.
I am asking if DATA or INFORMATION could be sent through a plasma faster than the speed of light.
I am not asking if energy or mass or matter can be moved faster than light. That is not in question. Read the article at the link below
RMCybernetics - Faster than Light Information? (http://www.rmcybernetics.com/science/physics/electromagnetism2_light_in_materials.htm)
PS. there's a new page on that site with some really cool pictures of a Tesla Coil discharging through fire!

1. Cherenkov Effect
One way to go faster than light is to make the light slower! Light in vacuum travels at a speed c which is a universal constant but in a dense medium such as water or glass, light slows down to c/n where n is the refractive index of the medium (1.0003 for air, 1.4 for water). It is possible for particles to travel through air or water at faster than the speed of light in the medium. Cherenkov radiation is produced as an effect.
When we discuss going faster than the speed of light we are really talking about exceeding the speed of light in vacuum c (299792458 m/s). The Cherenkov effect is therefore not considered an example of FTL travel.
Mosheh Thezion 01-04-06, 01:34 PM the speed of any vibration of an electric field will be limited to light speed..
and so frequency doesnt matter... it still flows at the same rate... from a to b.
and we could communicate faster than light.. if we stopped using electromagnetic based technology and developed high potential static communication.
the problem lies in being able to establish for example.. one line of force between two objects.. at great distance.
and then.. too modulate the line of force.. but not with any side ways force...
i.e.. no vibration...
i.e.. of we has POS P+-----------connected too ---- NEG e-.... all we need to do is physically modulate the electron only along this vector... <------->
in this way... the potential of the field line varied without any side oscillation....
but since electron orbit atoms... this becomes extremely difficult.. especially when we are dealing one or few electrons which are attached to a polar field of say 100 million volts.....
