So what about you simply answering the OP:Well simple consideration. Whole Earth is accelerating at g = 9.81 ms-2 but what does it make accelerate??? And where does it take the energy to give Earth so big kinetic energy?? It cannot accelerate just itself because it would violate the Conservation of energy rule. So I think that because of this UA model cannot work.
It was baked into the statement that he'd also be disproving inflation. Energy can be an inherent property of space. It's understood to be true today. The magnitude is what UA FEers would disagree with mainstream science about.
Let's look at your first post:
I'm excited. I think he's about to disprove cosmic inflation and UA at the same time!
For a start, what do you mean by "disprove cosmic inflation".
Are you seriously claiming that some hypothesis about the first 10
−33 to 10
−32 seconds after the "non-Big non-Bang" has any relevance to what is happening on the flat earth right now?
UA demands some source of acceleration equal to
g and there is nothing in of these any modern theories (other than gravitation) that approaches that.
You say "The magnitude is what UA FEers would disagree with mainstream science about." Of course it is!
Gravity on the edge of one of the most massive galaxies, Messier 87 (that one) is a factor of about
1/(4 x 1010) less than
g.
And
dark energy (in case you suggest that) competes with far weaker fields than that.
All the other guesses you make are likewise exceedingly small. So, again the magnitude is important.
You claim is no better than
flat earthers claiming that air refracts light, therefore refraction can explain sunsets on the flat earth .
Or getting "more (pseudo-)scientific", the atmosphere contains water (as vapour but they ignore that bit).
Water refracts light quite a lot, therefore the refraction of the water can explain sunsets on the flat earth .So, yes the magnitude (and direction) here is vitally important.
From what I have seen one of the reasons many flat earthers insist that the earth must be flat is to
avoid the "necessity" of believing in the "Big Bang".That reasoning is totally false as is easily demonstrated.
But carry on if you must.
