So, I've been told that meteors are explained by the pieces of the ice dome falling off. At this point, why is there not a hole
Just remember that this is my thoughts. Don't assume that all flat Earth theorists accept this or anyone else. I'm responsible if you feel you need to direct ridicule for it, no one else. Just understand this before we move on.
Ok, so why is there not a hole.
These are good questions and I'm pleased you asked them. Let's see if you can grasp the answers.
The Earth is continually sending up expanded matter, as in hydrogen and heliume, etc. Basically anything that has the energy apllied to expand into the atmosphere. Fair enough?
Ok, so in order for this to happen the elements have to be forced against the dome which is already frozen, so basically more are added against it and build up but build up slightly less frozen depending on energy applied as in the Earth sun sending them up.
As they build, just like an icicle on a roof, they start to form a mass that is applying more pressure onto the inner dome and being forced off. The dome is always intact.
and another question, what's the iron(Usually) things found in the craters?
You need to prove that they are craters made from space impact to be able to verify anything.
Also, how does it survive the air friction? The melting point of hydrogen and oxygen, which are the supposed materials of the Ice Dome, is -361.8°F (-218.8°C) and -434.5°F (-259.2°C), respectively.
It doesn't survive the air friction. Once the hydrogen ice falls, it falls into it's own sea of hydrogen liquid and sinks and melts kind of thing, except the melting that you see is friction which causes it to glow from your perspective due to the massive difference in pressure up there to down here.
As it gets slowly closer into more dense atmosphere, which is way further up, it is hitting extreme dense matter and is dissipated and eitehr send back up depending on the suns energy being at that point or it forms a cloud eventually as it's taken apart by the friction.
They don't just fall like bullets like they tell you and they are not full of iron and all that clap trap.
Any solid objects will be ejections from the central Earth's sun, like a stray spew of rocks from build up pressure, not dissimilar to a volcano eruption, kind of thing.
Another thing, how does it dislodge itself, and how do we see it on fire?
Another question I'm not getting answered, I assume.
Build up of mass no different to an icicle hanging from your roof, except for different densities, that's all.
The fire, as I explained,is simply the friction at the front as the icicle pushes through , leaving a friction tail as it ploughs through the atmosphere it is in up there.
If you've ever seen friction welding, think of it like that, except it's just different masses in different pressures of atmosphere.
