It's called a comparison. Try to keep up.
No, it's called dishonestly asserting your delusional BS to pretend reality can't work because it doesn't work with your delusional BS.
Your magical universal down doesn't exist in reality. So it has no place in the discussion.
If you want an honest comparison to your flat fantasy, compare down in reality (the RE model) to north in your fantasy.
Don't both saying would would happen if you keep digging down in your fantasy. Tell us what would happen if you keep going north.
If you kept digging in a round Earth, this would happen.
No, it wouldn't.
Assume you can survive the interior of Earth, you would reach the centre, where there is no net force of gravity of Earth acting on you, and every way is up.
Again, the round Earth has no underside.
That is you inserting your delusional BS where it does not belong.
Yes, that's great. But as I pointed out on a previous post, what exactly is there to keep above dirt and rock from compressing, until Earth collapses into a singularity?
You mean as you stupidly proclaimed, clearly without any rational thought?
Dirt and rock do not magically compress themselves.
They need a force to compress them.
And they compressed based upon that force.
If your delusional BS was true, you should be able to pick up a bolder and compress it into a tiny point.
You cannot. Because materials have material properties.
The atoms don't like getting smashed into each other, so they push each other away if you compress them.
So the question for you is what magic is there to compress the rocks beyond the pressure required to make a black hole?
On a flat Earth, there is actually something.
Really?
So what is your FE sitting on?
And then what is that sitting on?
And how about that, and so on?
Heavier objects sink with regard to the lighter surfaces that surround them.
We have been over your delusional BS with buoyancy countless times.
There is a force proportional to mass making things go down.
This causes pressure gradients in fluids which acts to push things up.
If the force from that pressure gradient is greater, the object goes up.
No need for your delusional BS.
We can also see that doesn't work anywhere near as simply as you want to pretend, by placing a lead weight on a table made of aluminium or wood.
The lead is much denser, much heavier, yet it doesn't magically fall through.
Once more, you are spouting delusional BS to pretend your fantasy works and the RE can't.
You simply must have realized the truth.
We have, and the truth is that you are spouting delusional BS, again.
And you still haven't addressed the problems with your delusional BS, and appear to be fleeing at all costs:
Again:
Zero-g in space is a result of free fall, not low pressure.
Objects in orbit experience zero-g because gravity acts on all of it to accelerate it together so there is no need to transfer force across it.
This also happens in the vomit comet, and is nothing like what happens under water.
Again:
Energy cannot be created or destroyed, it must be conserved.
So once an object is in motion, having kinetic energy, that energy can't just vanish.
Likewise, momentum must be conserved.
This means you need a force to stop an object. It can't just magically stop. That would mean energy magically vanishes.
And that requires an interaction with some object to stop it.
So what is a space craft interacting with to slow it down?
And remember, gravity doesn't take away energy, it coverts between gravitational potential energy and kinetic energy. So you need something else to stop it.
If you want to appeal to gravity, you need the orbit to intersect an object (e.g. a sub-orbital path), with the collision with the object stopping it.
