I am inert and the earth is observed to rise upwards to meet me.
Has anyone in the world on seeing something dropped, had a first instinct to say, hey look at the Earth rising up to meet the dropped object? Lunacy.
What is the scope of the universal acceleration? I read mentions of it as the Earth constantly accelerating. But wouldn't everything we see in the sky have to be accelerating also? I assume UA isn't bringing us rapidly closer to the sun, moon, planets and stars. So you propose that something hidden from us below the disk Earth is accelerating us, and something between us and the objects in the sky that is invisible to us is accelerating them also?
If you want to make the case for something below the flat Earth, obviously it can't be seen. But if something is also accelerating the sun and moon, what visible and
empirical evidence do you have for this force?
