Is 10K Resolution Possible for Faster-Than-Light Transmissions?

In summary: Heres another question, can we detect radio waves clearly 1000 light years away?Yes, it is possible to detect radio waves up to 1000 light years away. However, the signal would have to be extremely powerful for us to pick up.

Hey Gold, as has been said time and time again in discussions like these, we simply know far too little to conclude anything with confidence about non-detection!

Expansion is not the only factor influencing redshift, but is the most dominant factor. There is no other viable explanation for high redshift. If redshift was intrinsic, we should see high redshift objects superimposed over low redshift objects all over the sky. But not a single, incontrovertable observation of such has been found.
To clarify: There is a relationship between redshift and cosmological distance. The more distant an object, the more it is redshifted. The conventional explanation is that the universe is expanding and therefore all non-gravitationally-bound objects are receding from one another. This may or may not be true. If it is true, it in no way falsifies the concept that some objects have intrinsic redshifts.

and i believe its true, since there is overwhelming observational evidence that the the expansion is accelerating over time...
The 'accleration' factor (The Cosmological constant) is believed to have become dominant(over gravity) about 7 billion years ATB(afer the bang)..

Since we have only been sending out radio transmissions for about 100 years, do you guys think if there were a technological civilization let's say 100-200 light years from now they would have heard it?

Only if they were listening for it, which is hardly a foregone conclusion.

And plus the transmissions would have to be faster than light...which is quite impossible...right?
