Yes it is, but it doesn't work the same downwards, does it..and this is the argument in truth, because you call this the force of gravity and I call it denpressure.
Your gravity has no real explanation for why all this happens and mine does, yet mine is discarded and yours isn't. Why?
The simple answer is, you are a voice of the mass believers.
Any object that is heavier than the atmosphere it is in, will naturally stay at the bottom. Not because of fake gravity but because of the nature of how elements compact into their dense states.
Firstly, you need to accept the fact that there is
NO such entity, force, or phenomenon as your imaginary "denpressure". I defy you to find any reference to such a term in any physics texts from the last two centuries. Further I defy you to get any support for this "denpressure" concept from you fellow FEs here. You will find that not one of them supports it. Why? Because at least they have a basic understanding of elementary physics, and don't simply make things up on the trot in order to support their arguments.
Our "idea"—as you call it—of gravity is accepted, and has been, by scientists the world over for around 400 years (Galileo and his early tower of Pisa experiment, ans Newton's confirmation in 1687). Are you seriously suggesting that the millions of scientists since then who acknowledge gravity are all mentally deluded, morons, liars, or part of a centuries-old global conspiracy? Really?
Do you not wonder—for even a moment—why there exists a body of "mass believers" that accept the gravitational theories?
Gravity explains so precisely and simply so many concepts we take for granted, but which you choose to willfully ignore: ski runs, bathroom scales, pumps, see-saws and swings, pendulums and mechanical clocks, roller-coasters, artillery and archery, hot-air balloons, waterfalls and clouds and rain, ball games, space shuttles and satellites, ballistic missiles, flush toilets, elevators, ferris wheels, ten-pin bowling etc etc etc.
Without the force of gravity,
none of these things could exist in their current form.
And your assertion that "elements compact into their dense states" needs some sort of detailed explanation from you, as there's zero physical, scientific evidence that supports this idea.
