I'm not entirely sure you used the term strawman correctly.
I am.
You are dishonestly misrepresenting the RE model, pretending it is something it is not, so you can attack that misrepresentation rather than the RE model.
That is a strawman.
A key part of physics is no preferred directionality.
This means that if you want to discuss the underside you need to have some reference for where down is.
That's funny, because when I discussed the idea of no preferred directionality in another thread...
I basically got sass.
I wouldn't call that sass.
You could not explain the directionality.
If no directionality is preferred (because you need to have the Earth round) then it is fully possible to rotate directions, and indeed push objects straight up
Without gravity, yes.
Gravity provides directionality.
Either we have non-fixed directionality and you have to account for multi-directional movement including straight up walls and ceilings, or we have a fixed directionality toward the bottom of the Earth (FE or RE), or we have semi-non-fixed directionality and a FE.
Or I can pick reality.
We have no intrinsic directionality, and directionality comes from interactions.
That means if you have a large sphere in space, in free fall, well outside the Roche limit of other objects, down is towards that object and up is away from it.
No need for a magical, inexplicable down.
So why is it that objects fly?
Because multiple forces act.
I create a random object with a dense magnetic & metallic center. All objects should be pulled strongly toward the center. For purposes of this experiment, this object's outside is a sturdy water bucket (holds 20 gallons of water) made from indestructible plastic, while the core is a floating orb in the center of the bucket that has equal mass (compressed and proportional to the surface space) to the Earth. Basically, I'm creating an experimental microcosm. It ought to supposedly stick any gravel, sand, and water into it, while leaving everything outside the bucket alone.
Why would it magically leave everything outside the bucket alone?
But there's a problem. I introduce a bee hummingbird (since the experimental space is small, so must the bird be). The bird is not grounded. It flies out of the bucket going back to what you call normal gravity. It's not stopped by that either. Neither is a helicopter, jumbo jet, or hot air balloon.
Wrong again.
With the mass of Earth placed into a region smaller than a bucket, the gravitational attraction would be much greater.
If it was an orb with a radius of 6.371 cm, then its radius is roughly one 100 millionth of that of Earth. And as the force of gravity scales as 1/d^2, that means the value of g for that orb would be 10 quadrillion times that of Earth.
Your little bird would fall in and be killed by that force.
But ignoring that, and sticking to just reality, where birds can fly, that is because another force acts.
Gravity is not magic. If you have a strong enough force acting opposing gravity, you can have a net force acting in a direction opposite the force due to gravity, allowing birds to fly.
If you remove the wings, the birds can't fly.
If you remove the helicopter's blades (its rotary wing) or the jumbo jet's wings, they can't fly.
If you allow the air in the hot air balloon to cool, it can't fly.
They all need an additional force acting.
Yes. There is. Just because your "scientist" gurus say no, doesn't mean that's the case.
No, there isn't.
Your irrational hatred of the RE model, and wanting to strawman it by pretending there is an underside will not change that.
If you wish to claim there is an underside, then tell us what location on the RE is the lowest point, and most importantly, WHY.
If all force were equal, we still have other forces to work with! Even central gravity, you're basically describing a sort of magic that mysteriously violates angular momentum. Or do you want to answer this question?
The one clinging to pure magic here is YOU! Where you want to claim things fall for no reason.
What question?
Why things can be pushed on level ground but not up?
And why it accelerates when going down?
Because gravity pulls it down. When you move it up, you need to apply a force to overcome gravity.
When you move it down, gravity pulls it for you.
When you move it level, you are neither fighting gravity nor having it assist you.
If you mean your crappy drawing, again, Earth is not a tiny ball, neither is Hyrule.
Meanwhile, if you were honest, you would tell me that Link's eyes cannot see around corners.
I am honest.
I'm not the one blatantly lying to everyone repeatedly, with pure BS like a clearly irregular terrain magically being straight.
That would be YOU!
Do you know why you can't see around corners? Because objects block the way, e.g. the corner.
We can even use a doorway as an example.
The wall around the doorway blocks the view.
An honest person would admit you can see through the doorway to the other side, seeing objects on the other side of the door; where it is when the line of sight is obstructed, such as trying to look straight through the wall, that you can't see it; clearly demonstrating how obstructions block the view.
Conversely, dishonest people want to pretend that this magically means there is some distance limit to your eyes, where perspective magically cuts off your vision, as if you can't see someone standing on the other side of the doorway, because of the wall to the side, even though the wall doesn't block the view.
Now, maybe if you didn't double-down when caught in lies, and shift the facts to whatever you want them to be to suit the purpose at hand, we could actually have a real discussion and not just have alot of crap.
And more pathetic projection.
You are yet to catch me in any lines. Conversely I have caught you in plenty.
You happily lie, making up whatever dishonest BS you think you need to pretend your delusional BS is true.
There have even been plenty of times where you contradict yourself, and switch back and forth between different contradictory blatant lies to pretend the RE must have a problem
If you want a real discussion, try having one.
Notice how yet again you avoided the real issue?
Whatever magic you appeal to should work equally for UA or gravity. So the floating islands do not need a FE.
You know you have no rational response to this, so you deflect with whatever dishonest BS you can muster to pretend RE must be wrong.
We can't climb walls or ceilings, we can't push objects uphill, but you say gravity is not fixed.
Why should we be able to?
Again, you just assert delusional BS with no justification at all.
Why don't we get sick in the same way as jet lag, when we walk over the equator? Or around certain points of latitude or longitude? Even if gravity is centered, the liquids inside your body should be doing this.
Again, WHY?
Stop just asserting delusional BS and try explaining it.
Why should we magically get jet lag from walking over the equator?
What makes the equator so magically special?
Why should any other point of latitude or longitude magically cause that?
