Nothing can strike the dome.
Then why did you use an analogy involving a foolish man who cannot see a sliding glass door (much like a bad 90s sitcom) to illustrate the fact that "Nothing can strike the dome"
You only get dome hydricals and helicals and nitricals, etc.
They're what you would view as meteors and comets and what not.
They're the dome fallers that you see in friction burn ups in the sky.
Icicles made of hydrogen, helium, and nitrogen would not explain fragments of meteorites that have been found all over the world.
Oh, right. Those are ALL fakes, according to nobody except you.
