comment If the hammer and feather move at the same speed why do comet and the tail particles move at different speeds?
The ejection speed of the comet material is negligible compared to the solar winds carrying it into space. So while it does impart a bit of velocity, it does not explain the "slow down and fall away as it disintegrates" effect the author is asking about.

comment How to build a powerful home made telescope
It would not be possible to actually answer how to build a powerful telescope in this type of Q&A. I would suggest doing a bit of research to get started and ask questions about specific problems you may encounter.

comment iteration to cover the whole sky with right ascension, declination, angle
@Envite Do you happen to know the percentage of overlap you get with this configuration? In other words, how much of the analysis would be redundant/wasted if you were forced to analyze the entire field with each step?

comment What is the maximum transmission distance of the radio signal in the outer space which could still be understood?
This feels somewhat empty and unsatisfying. The entire field of Astronomy is about measuring and theorizing about places we have never been. Surely we know something about the physics of radio signals in a vacuum and can surmise the effects of interstellar space on signal degradation. Maybe the author didn't provide enough information to define the problem, but saying "don't know because we haven't been there yet" just feels a bit lacking. No offense; I just don't think your opening premise is correct.
