Helium doesnt burn in any meaningful sense, noble gas named as it doesnt do a lot. Hydrogen burns with a barely visible blue flame - if there is a burning H2 leak you often can only find it from the heat it gives off. Auto ignition of hydrogen is around 500 deg c (freezing point -262 deg c iirc) helium is non flammable
Keeping your mind on it at sea level will not help you understand it high in the sky.
You say helium doesn't burn but you need to understand friction burning.
Metal doesn't burn but friction glow can occur.
Up at the dome the ice will not be like ice we walk on down here. It will be ice that is the result of massively broken down matter, namely hydrogen/helium, etc.
Once that ice drops from the dome it will be under friction and it will glow and turn back to a gas, hence why you see the tail.
It makes no sense because it's scientifically illiterate.
Of course it is, to you and others who think rocks can simply float around in a nothingness of space and also orbit at ridiculous speeds.
I honestly and truthfully do not expect you to come out with anything other than this. Why would you?
Your mind's made up.
There will be others who will actually sit back and ponder it all and think " you know what, there could be something in this."
As far as you're concerned there won't be but that's fine in my book.
Outer vortex, that's a new one you have made up for this answer. Never been mentioned in this thread before.
It has but I used a sink and plug hole analogy and it got lost on those who saw it. Maybe you didn't see it or it got lost on you.
I can't help that, I can only give out what I think by how I explain, which obviously will be far from most people's cup of tea.
It's amazing how quickly you can glue words together to plug holes in your "model" almost as if it was being made up on the fly
Or already thought of and only coming to light because it was overlooked.
