If the earth is flat and if the dome is ''hemiplanic'' (meaning like a round bowl turned upside down over the flat earth).
Is there some point where the dome meets, or rests, on the flat earth ?
Does the dome meet , or rest , on the top of the ice wall ?
Is this ''dome'' something solid ?
(My apologies for the use of the word ''hemiplanic''.....I couldn't think of a flat earth word for ''' hemispheric'' if you get what I mean. LOL)
In models with a physical dome, generally it and the ice wall are connected. There may be regular ice leading up to the wall proper, maybe some kind of gradient, but generally that's how it works.
Also the word is hemispherical. They use hemiplane to refer to half a plane. A dome is not half a plane.
You mean that the expansion only acts on the up down direction. Makes sense. But this case a person on a plane would weight less that on Earth.
1. They do. 2. Why? The expansion could happen at a specific height.
But those that promote this Expansion of Space commonly uses Cosmology's expansion of epace as a justification of their hypothesis.
No, they don't, you were just physically incapable of letting that straw man go despite being corrected way, way, way too many times. The only time that ever gets brought up is to point out an REer's hypocrisy in accepting sufficiently large and accelerating expansion of space in their own model, and rejecting it in someone else's. Something you are a spectacular example of, so no wonder you hear it so much.
This is also completely incorrect because the expansion of space does not cause gravitationally bound objects even up to Galactic Groups to move apart.
This expansion of space does not "drag" objects with it in such a way that could overcome the gravitational forces between the earth and the sun, moon, planets and stars.
And we went over this before too, and you also evaded it. Once again: that's not how gravity works. Gravity does not have a finite limit, the force has denominator r
2. That never becomes zero. You are exerting a gravitational pull on stars we can't even see, it's just tiny. If gravity magically equalled no effect from expansion, then expansion as a concept would never be noticeable.
What you in fact mean to say is that the expansion of space can overwhelm the force of gravity if it is sufficiently big. Nothing is getting dragged, falling objects just have further to fall. Gravity does not stop basic physics from working. Under RET the expansion of space is small enough in those locations for gravity to be greater than it; that is not a property of being 'gravitationally bound,' it is a property of those specific cases.
It isn't that it 'can't' it's that you 'don't want it to despite it being perfectly possible.'
If the Earth is infinitively wide, it will still expand. Mathematically concept of infinity can be applied. See the hotel paradox? Multiply every number smaller than infinity by 2 is possible.
That's finite numbers that get multiplied. You don't expand infinity, by definition.
