6. The dome can be indirectly observed via meteorological phenomenon such rainbows and halos.
Well, interesting stuff you wrote above... So,
genius, how rainbows or halos relate to your fictionary "dome"?

Example: rainbows are well known meteorological phenomenons caused by the light of the sun being refracted by droplets of water acting as prisms.
White light, once reflected, refracted and dispersed, takes the form of a multicoloured arc or spectrum of light always appearing in the section of sky directly opposite the sun.
I'm wondering where is the relation with your
imaginary dome... chances are you believe in the pot of gold at the end of the rainbow too...

Ok, I'm waiting for your reply!

PS: I'll start posting bits of
reality for you and your troll friends:

Light through water alone does not produce rainbow. And btw why is rainbow always the same shape? Start to think Guido. Don't be fooled by monkey man science.

And a small bonus for Guido
