And, since you have nothing to offer but bloviation, I will remain "ignorant," no thanks to you. i have paid attention, and all you do is make broad generalizations and speculations, and offer no insights whatsoever. You do nothing to alleviate "ignorance." It is all sophomoric b-s-ing. I got my fill of that in college. GPS satellites are not time travelers---unless you want to say that we are all "time travelers" by virtue of aging. But that is laughably trivial, and a cheat on what "time traveling" is supposed to mean. Photons don't travel from the future into the present, nor do we sent them from the present into the past. Too many internal contradictions. (A great article by Gregory Benford---"The Tachyonic Anti-Telephone---debunked supposed reverse time travel by superluminal particles.)

I don't do "hints," so what you are doing is reading a Rorschach blot. There is no message in such a thing. I'm more interested in the tangible statements about current political situations.

I spent a 40-year career doing system analysis and design, so I am quite familiar with abstract concepts. I have three degrees in applied physics, so I don't have to prove anything to you about my learning ability.

I'm not steering clear of anything. You haven't offered any crumbs, so what is there to steer clear of? You don't have any "arguments," just a series of rhetorical questions and speculations (when they aren't truisms).

In the whole progression of this dialogue, I see you walking back certain immoderate claims and seeking to carve a hole where you can fit by making generalizations. All you can do is make reference to notions that one picks up by reading popular science publications. Not interesting. Sorry.
