Sure there is. Up is the direction that the UA is pushing the FE.
That poses a few questions:
1) What is "qualified" and what isn't qualified for being accelerated by UA? That should be a fundamental question, since everything else seems to be accelerated except of us and the ground.
2) Is there anything that is actually stationary? Because if there were stationary light emitting/reflecting bodies, we would probably receive massive amounts of radiation due to the blue shift.
3) Is every other celestial body a solid rock? Because if they weren't, they would be shedding matter all over the place. Except if everything on them is accelerated by UA, but you haven't told what is and what isn't accelerated by UA!
4) That poses another question, what are comets, shooting stars, etc.? Why are they accelerated "less"? Are they accelerated at all? If not, then why are they not moving at immense speeds compared to us?
5) What force keeps celestial bodies revolving around us and the moons of other planets revolving around them? Are they not affected by centrifugal acceleration? What qualifies as being able to revolve?
6) Why does the Earth still have an atmosphere? If it was a disk, it should be gone by now. If you don't believe me, try to keep a bunch of water on a flat disk without getting spilled.
7) Why can I see satellites and the ISS with my telescope?
