"The detection system and even the nature of the EM Signals here is not particularly important."

Au Contrare!! They are of the utmost importance! It is the entire basis of your theory. All theories and science is like a house of cards. If the foundation falls, so too the entire building upon which it is built.

If you cannot support your theories and ideas by giving details about the foundation upon which it is built, then you are going to have very few interested parties, except those that are into buying bridges unseen.

Don't get me wrong, here. You may in fact be entirely right. I'm open to that possibility. Please try to see what I say as sharp constructive criticism.
