Is it possible to communicate instantly across distance?

[haoest]

Imagine if there were a very strong string, so long that it extends from the Earth to the Sun, and so strong that pulling it would not cause any change in tension. Light would require a minute to get from Earth to the Sun, but pulling the string would signal the other end instantly!

 

Possible?

 

 

 

 

[Schrödinger's hat]

The tug on the string would travel at the speed of sound (of the string).

Much slower than light.

 

No matter how rigid the object, the way its components are interacting with each other is by exchanging photons (for the most part, nuclear forces and gravity can be involved as well, but gravity travels at the speed of light as far as we know and so do the strong/weak forces), so the signal can only travel at or less than the speed of light.

[Enthalpy]

Relativity makes the assumption that information travels at most as fast as light does in vacuum. Then it can explain why Lorenz' transformations are meaningful.

 

That's why neutrinos faster than light is a serious worry if confirmed. They're produced at will, and detected... well, some are detected. So they are a means to transport information.

 

Other experiments with a wave guide used below its cut-off frequency, hence carrying a fading wave whose phase speed is infinite, claim to have transmitted a modulation, hence information, without delay over a limited distance. The limit must be more subtle, like: the amount of data arriving too early is limited, increasing it slightly requires impractical power losses. Just like any computer modem violates the energy-time inequality by transmitting more than pi bits per second per Hz of bandwidth, but does so by using a big signal-to-noise ratio, and hits a hard limit quickly.

 

Intricated particles share a synchronized behaviour within a delay smaller than light needs to travel between them, but acting on one particle doesn't influence the other, so it's not a means to transmit information.

 

Gravity waves should propagate at light speed... This is consistent with the energy and momentum loss of an observed pulsar pair. But gravity waves escape our detectors up to now, and this might indicate a flaw in present understanding.

 

I haven't seen anything about the propagation speed of the weak nor strong forces. Present physicists would naturally assume "c at most". As these forces are observed over tiny distances, any argument about their speed must be indirect.

Enthalpy - I've never heard of intricated particles, do you have any links where I could read up on them, or is this a translation blur of entangled particles; which agreed do not allow the transmission of information

[The time Traveller]

On a humorous note I would say yes and the answer is bad news it can travel faster than any thing I know of I think it abides by its own set of laws .

 

The other answer would be to put your information on to a electron /particle by encoding it they can disappear and then reappear in two different places at once instantaneously this will lead to the next quantum super computers

How, exactly, do you do that?

Oops, exactly.
