Uso, are you applying 21st-Century physics and math to something tens of thousands, if not millions of years ahead in our 'future'? This is a science fiction setting, and should be treated as such. The guidelines and submission rules require that it be plausible, not a dissertation on Quarks and Quantum Particles.
If things like Aether, 24 Kilometer-long behemoths, planet-killing single-shot weapons, floating tentacle monsters, and a race of intelligent, cat-eared female androids that purr are plausible, I don't see why a stealth shield based on gravity (which is well-written and in the correct format) shouldn't be plausible. Things far stronger are currently in the setting, things far more dangerous make an active appearance on the battlefield.
Needing a Ph.D. in Physics to merely submit an article on a Science-Fiction Roleplay site is both ridiculous and asinine. I hadn't even remembered about the inverse square law until you brought it up again while tearing apart several submissions (not just this one) and I still had to look it up to even understand what you were talking about. How do you explain the Misshu, FTL, and Aether with hard science? You CAN'T. Because it isn't about the physics, it isn't about the math. It's about people trying to escape from the real world, and have a good time participating in something distinctly unreal. Because, honestly, how many of the people who participate on this site have killed a freakish monster, rode in a sleek warship, or saved the universe? No one, to my knowledge. SARP is a way for people to escape from stress, to embrace a good story with good company. SARP isn't another classroom with a sudden Pop Quiz. Whoops! You didn't study? Too bad.
My first rant aside, Stealth is a part of the HSC culture. How are they supposed to live up to their great history of hiding from major-faction ships? Of ambushing convoys? How is it possible? If we stuck to the hard science, they couldn't. They'd be spotted long before they were even close enough to shoot an angry glare. Their stealth capabilities are an integral part of the HSC faction, and forcing Nashoba to fight for something that has already been established is wrong.
Furthermore, you have ignored the guidelines you agreed to follow. You haven't suggested any alternative solution, you haven't said anything positive about this submission (and many other submissions) at all. You have to work with the submitter, not against him. Again -- we shouldn't have to have a Ph.D. to get our tech approved.
This issue needs to be resolved.
