Is this information traveling beyond speed of light?

If we could make a really long piece of twine long enough to reach from earth to mars, and put one person on each end - suppose the twine is incredibly strong, essentially an inelastic material, and one person on mars gives it a tug and the person on earth feels it almost instantly, in like .0001 seconds, that would be information "the fact that a 'tug' happened" traveling faster than the speed of light. Is this possible?

Is this possible? No. The wave traveling on a sting is incredibly slow compared to the speed of light. It would take hours (or more) for the wave to make it from earth to mars.

:lol:  Yea, I was half tempted to put "Holy shit!  Nobody has ever thought of that before!"  but I decided to play nice.

:shake: How frustrating. You failed to address the obvious factor in the speed of this wave, which is the limit of its material hardness. Can a material be theoretically hard enough to let this happen? I am curious. AND DON'T MAKE FUN OF ME!!!! :crankey:

A common misconception that internet people have is that faster than light communication can be done using a group velocity. That is, when two waves are superimposed, a wave packet can be formed that travels faster than light. However, this does not violate relativity and does not allow communications faster than light.




I remember watching a PBS program about group velocity. They showed the experiment with microwaves going through brass faster than microwaves going through vacuum. Next, they modulated the microwaves (with music) and demodulated the 'faster than light' microwaves on the other end through a speaker. Very sketchy, noisy music could be heard. The 'scientist' claimed that the music was proof that information was being transmitted faster than the speed of light. It took me a while to realize that the information did not travel faster than the speed of light. The music was recognized as music because humans have learned what music sounds like. Had they sent a sequence of random numbers, the results would have been much different. It is very easy to deceive oneself, even for a scientist.

So what you're saying is the local rub and tug isn't doing me light speed justice for my dollar.  I'd better get a tax right off for this:crankey:

When you're playing with distances such as these, it's the very fact that the twine IS elastic that screws up its ability to go FTL.

Theres only one thing faster then light son... and thats quantum tunneling.



"In quantum mechanics, quantum tunneling is a micro nanoscopic phenomenon in which a particle violates the principles of classical mechanics by penetrating or passing through a potential barrier or impedance higher than the kinetic energy of the particle.[1] A barrier, in terms of quantum tunnelling, may be a form of energy state analogous to a "hill" or incline in classical mechanics, which classically suggests that passage through or over such a barrier would be impossible without sufficient energy." - wiki

Also, space expands faster than light.

:rocket:

edit- wait tunneling?  no, tunneling isnt faster than light.  Unless your playing tricks with phase/group velocity like I mentioned above.
