Brain Storming is good, it allows both FEs and REs to participate and try to help each other in the issue.
I would go for the idea of the Sun projecting "Repulsive Radiance" (RR™) towards Earth down below.
You can think of "Repulsive Radiance" (RR™) as the same of atomic nuclear force, it attracts electrons that has opposite polarity, but does not expunge the protons tied together, even having the same polarity. The repulsion itself is proved by the fact that no electron plunges and it is consumed by the nucleus - even being strongly attracted, it is also strongly repulsed. The scientists also have plenty of calculations and formulas to explain the Sun's flares and winds that can blow matter far away, the case of particles and gases from comets, forming the long trails.
So, "Repulsive Radiance" (RR™) is caused by the extreme energy from the Sun projected towards Earth, it repulses Earth and everything on it downwards, while the Sun itself becomes repealed by the masses below, so it stays up at a distance, like floating.
I could, in time, come up with a physics formula, trying to show Repulsive Radiance (RR™), may be something like that:
RrV = (Rra x m ÷ Ea) x eV x sin(a) ÷ d²
RrV = Radiance Repulsion Vector
Rra = Radiated Radial Area in km²
m = sum of all masses
Ea = Earth Area in km²
eV = electron-volts, energy generated by the Sun
a = angle of radiation vs angle of Earth
d = distance between the Sun and the Earth
Note that I did not include "steradians" in the calculation, due considerations of a non spherical Sun or Earth in this case study.
This (initial) formula could explain why the Sun stay afloat above Flat Earth, as well, why everything is pushed down against the solid solid Earth underneath, considering not only the edge is solid ice, but the bottom of the flat earth is also a very tick ice base.
Of course I don't believe in a single word I post above, but a brain-storm process relies exactly on that, go out of your mind and find possible alternative explanations. If Einstein was under effect of some acid when he came up with the idea of space and time could deform, become plastic, elastic and dilute itself under presence of mass, I don't know, but there is a chance. If this was the case, hours later Einstein probably thought "wow buddy, that is a great possibility". Most musicians and artists sometimes need a "stimulae" in order to reach nirvana and get out of the box. For decades, "brain-storm" means exactly that, you need to turn off all your locks and even the logical, psychological and cultural bias and let the brain to process junk, like a dream. It may looks strange, but I already found path for a complicated Sin(x) calculation 24 bits routine I was doing in assembly language, while dreaming, woke up in a jump, rush to the computer. It is not rare for me to find answers while showering, try to explain that.
So, may be the above formula could be part of a larger explanation about day & night on FE. At least now we could explain the "push" of gravity from above and how the Sun floats. Oh, I forgot. The Repulsive Radiance is also reflected by the Earth's surface back towards the Sun, and that is what makes it move forward in a circular motion towards the West at angular speed of 15° per hour. So that also explains the Sun's movement above. That also, could be the basis for ocean tides.
Now no one could say I am a polarized insensitive RE, not at all, see, no FE even thought about RR™ up to now, and here I am, giving it for free.
