First stage: it was Universal Acceleration


 The rate / value of acceleration because of gravity is not uniform on the earth.

It has measurable changes on earth due to earth not having uniform density, and changes with height like seen at the top of Mount Everest.

There are 'mysterious' energies from above, but it is measurable, at least you can feel it by your own body. There is downwards pressure.
That's why weights are not really equal in different places.

You can feel G-force. But this is basically motion strain. Whiplash. On roller coaster rides, you can be utterly certain of how "gravity" behaves.

This is why Newton's random musings have been able to prevail, it is a great lie with that grain or two of truth. We believe in the "equal and opposite" theory because we feel motion strain.

 But two rides show us the the truth:
https://amusementrides.org/a-list-of-amusement-park-rides/
1. What is usually called Gravitron, but is here called the rotor. A room spins at high speed, meant to emulate the 1000+ mph (16 miles per minute) spin of the Earth. Instead of the expected force though, this ride launched you straight up! If you have eyes to see, this is pretty clear indicator that the idea that Earth's rotation "creates gravity" is a lie. Oh also, you're pushed against your seat by the force.
2. Tilt a Whirl. At the surface, it seems like it should prove there is G-force and thus gravity. But then you realize that your body would adjust to the motion, it's when it changes direction or speed that you get whiplash. Unfortunately for Round Earthers, they have proposed an Earth with about four types of motion. Earth should constantly change direction and speed, and we should be in constant whiplash.

This mysterious force is enough that Newton was able to claim credit for his crackpot theory. But it appears to be a force of momentum not downward pressure.

You mean where gravity is still in effect. And drives pressure gradients that makes buoyancy / separation possible?

It stops all momentum. That's what you said. That's what we heard. And it does so, regardless of air resistance?  Can I quote you on that?

So if I fire an arrow from a bow, you will admit that it falls not because of the curvature, not because of wind resistance, but that (by your own admission) it has lost momentum, and its mass causes it to sink?

Where buoyancy is in effect. And you can see for yourself that your so-called gravity is a lie. Instead of air resistance, you get water resistance. And then it sinks again when it loses momentum. In fact, you should go to a big aquarium in the city and show sharks this trick. I imagine they'd be impressed for all of nine seconds enough not to eat you.

The mystery could be described as a work of satans/Lucifer that has unimaginable machineries all over the world in order to cleanse the heavenly aura of this life as meant in initial creation. Besides to create diseases and mortality among Adam's descendants etc. etc.

(If you believe in religion).

Trying to change the subject.  Stupid.

Quote the Bible where salvation is dependent on the shape of the earth in another thread.  Stop derailing this thread.

He's basing this on the idea that this is model is the work of Satan to get us to see ourselves as tiny specks in an uncaring universe. But this is the idea of wicked humans. Most of whom want money above all else. Round Earth is a NASA/globalist ptramid scheme for those who want money and power.

What a F’n word salad.

With no gravity in the flat earth delusion.

Why does a brick thrown straight up in your model you claim there is no air resistance.  Why does it slow down at all.  Loose all upward momentum.  Change direction of travel 180 degrees to ACCELERATE back to the earths surface.

How is that possible for the brick where there is no external forces to the brick in your delusion.

You can create all these imaginary holes that only make sense to you.  It just highlights the weakness of the flat earth delusion. And it cannot come up with a model to supersede reality, or a model that can better predict reality. 

Are your sure your not here to make flat earth look stupid.

But lemme save you a headache. Said brick loses momentum, (does it really flip over?), and then sinks to the ground.
But why?
The answer is quite simple, gravity.

Toss the brick up through the water and watch it fall back down through the water. Nothing has changed.
Sure it has.
The water has resulted in more buoyancy, meaning the acceleration due to gravity is reduced.
It has also provided a lot more drag, so the brick slows down much faster.

Now again, can you tell us what magic gives mass/density its directionality to cause it to fall in any particular direction at any particular rate?

We believe in the "equal and opposite" theory because we feel motion strain.
We accept this because it is backed up by mountains of evidence.

meant to emulate the 1000+ mph (16 miles per minute) spin of the Earth.
Pure BS. It is not meant to emulate the spin of Earth at all.

this is pretty clear indicator that the idea that Earth's rotation "creates gravity" is a lie.
A pathetic lie put forward by FEers to act as a strawman to knock down.

Earth should constantly change direction and speed, and we should be in constant whiplash.
Why?
Again with pathetic vague claims.

But it appears to be a force of momentum not downward pressure.
Do you understand what any of those words mean?
Momentum isn't a force.
Pressure would act based upon area, not mass.

you will admit that it falls not because of the curvature
Who is suggesting it will fall due to curvature?

its mass causes it to sink
No, as mass has no directionality. It shouldn't cause things to sink anymore than it should cause the same object to rise or to fly fowards.

What you have is gravity acting to accelerate the object, which eventually results in the arrow hitting the ground, unless you somehow fire it fast enough to go into orbit or reach escape velocity.

Where buoyancy is in effect. And you can see for yourself that your so-called gravity is a lie.
Buoyancy relies upon gravity.
So it certainly doesn't make gravity a lie.
Without gravity you have no explanation for buoyancy.
With gravity, you have the weight of the fluid above causing a pressure gradient such that objects immersed in the fluid will have an upwards force from that pressure acting on them to push them up.

Explainer: How do mass and weight differ?

https://www.snexplores.org/article/explainer-how-do-mass-and-weight-differ

Weight is a measurement of the gravitational force on an object. It not only depends on the object’s mass, but also on its location. Therefore, weight is actually a measure of force. In the United States, most people measure weight in pounds.

Let’s say that your body has a mass of 40 kilograms. Your mass is 40 kilograms on Earth, on the moon, on Jupiter — and even floating inside the International Space Station. Your mass is 40 kilograms no matter where you are. But your weight differs from place to place because of differences in how hard gravity at each site pulls on you. On Earth’s surface, 1 kilogram of mass is equivalent to 2.2 pounds of weight. So your 40-kilogram mass on Earth would weigh 40 x 2.2 — or 88 pounds.


I have no idea what point you thought you were making?

If you an algebra problem and there is a value/variable on both sides, the thing is irrelevant.

x+ 2v + 2= 2v + 4
x + 2 = (2v-2v) 4
x = 2

As you can see, 2v was basically pointless. Whatever value it had became zero as it was wiped out by itself. This is the same as 2v not existing at all.

I understand the math.
 
You don’t get that weight is mass times the gravitational constant.  (or force is mass multiplied by acceleration) when you solve for mass you get mass.

The masses are equal, but you don’t get to “cancel” them out.  Each mass is still there, but in equilibrium.

In class three levers you need g to make the equations accurate and be able to predict real world models


https://www.school-for-champions.com/machines/levers_classess.htm#.Y2hx5yVOmEc




Bicep is the effort for the lever, and measured in force.  Not mass.  The load on the hand is mass * g which is weight, or a force….

Why are bridges rated by weight, not mass?

Let's suppose I have an extra long truck. The truck is a long cage similar to a chicken truck. The truck in question carries pillows. Lots and lots of pillows.

The weight of the truck is probably more than the weight you mentioned. But the freight cart is not very heavy because it has a thin cage instead of full metal. Also individually, each pillow doesn't weigh much. So a 2.5 ton truck with a long long trailer weighs about 9.5 tons, but all the weight is scattered over a fair distance. It probably won't harm the bridge... but it won't be let in anyway.

Ton of feathers vs ton of bricks.

Why are they weighted by weight, not mass? Mostly because we don't design super-long ultra-light freights for the most part. They are cumbersome and hard to maneuver, resulting in just as much a hassle to the bridge as a dense and heavy truck. Accidents and such.

No.  Because the amount of force is calculated per axel to over simplify.  Because the mass of the truck is under the force of gravity that “fuels” the capability of the truck to distort / break a bridge if its over the bridge’s weight limit.

Bridge Formula Weights
https://ops.fhwa.dot.gov/freight/publications/brdg_frm_wghts/


Mass doesn’t have the means to damage/work on something unless it has force.  A solid shell shot into a bridge can damage the bridge because it can apply a force.  The same for the truck.  As a truck drives or sits on a bridge the force of the truck applied to the bridge because of gravity can damage /work on the bridge.

The point is.  A truck can overload a bridge and damage it.  The reason a truck can damage a bridge is because gravity gives the truck the ability, to oversimplify, to do work.  The truck under gravity can force a week element to bend down and deform or break.  What property of mass or density can cause a piece of steel for example to bend / distort to a breaking point without force behind it.

The samething for a waterwheel tied to a grind stone.  If water is applying to the drive.  The water has to impart some force to the grindstone.  The water under gravity applies a force to the water wheel that causes it to transmit a force to the grind stones.  This force overcomes the friction of the grindstones to turn them. 

In your zero gravity flat earth delusion, where does the water get the force to turn the water wheel that in turn transmits force to overcome friction so the whole system and operate? 

In your flat earth delusion, there is nothing to give force to the water to impart it on the grindstone to turn.

As an observation, with no explanation.

This means this formula is a lie.
No, it means this formula is used to explain the previous observations.

As you can see from this formula, g (gravity) is immediately crossed against itself. In other words, it is irrelevant to the the equation.
No, it means it acts on both sides of the equation.
Being able to cross it off doesn't mean it is irrelevant.

This is most obvious to see when g is 0. In this case there is no buoyant force and no weight.
This means there will be no precise amount of fluid to displace.

Ever notice thar the observed pressure gradient seems to be related to altitude?

E.g. Underground or underwater, if you quickly move to ground level, you will suffer from the bends. Likewise, your ears pop because air molecules continue to be more spread out, the higher the altitude. Decompression sickness.

Gravity theory has no explanation for why this is. Buoyancy theory, however does. Same process underwater as climbing a mountain.

And btw, these formulas that use gravity in buoyancy are all dated after Newton, meaning all of them are rubbish.

The origin of "bouyancy" is from differences in density; gravity is usually the relevant force but any force will do, for example the centripetal force. So, bouyant flow can occur in the absence of gravity; for example, you can separate air from water in space by rotating the container- the air will migrate to the center.
In conclusion, gravity is not necessary for density and buoyancy. Forces already exist that explain this process. What forces? I'll talk about that below.

So what's the explanation? Well, each upper layer is less dense than the one below it. We have space (where lack of much of anything is more common than air), air (air is more common than space), water (water is more common than air), lava and rock. Each of these layers, the atmosphere is more dense, and changing suddenly creates pressure issues. This is cohesion, not gravity. Particles are close together in loose bonds. Because of their own buoyancy and density, each layer is in order.

 Because more dense objects cannot reach a layer of atmosphere lighter than them, bricks fall, fish tend not to fly into the stratosphere, and deep sea diving devices need either downward propulsion or to be dragged down by some kind of heavy weight (lighter object trying to enter heavier atmosphere).



I muted much of this because I have no truck with NASA. But around "water droplets in a bubble in a sphere" we see that the air/water inside the bubble is unable to escape, since they have created a strange ultradense layer, and the less dense outside means the bubble bounces off when it attempts to escape into lower density. No gravity just water difference.

No, sorry, I won't answer that question. Because it's already solved. Mass is .286. Also, the formula is outright wrong because it assumes gravity exists and then extrapolates mass and density with with gravity (yes, you measured radius and length and spit it through .986 for gravity, and assume you know its mass. But you don't. This formula doesn't tell us whether this bobbing object is wooden cork, hollow piece of metal, solid piece of metal, or a solid cylinder of purest osmium). You don't need a buoyancy formula. Weigh the water. Weigh the empty container. Subtract the two. Weigh the object, and adjust for density. Compare the two. If an object is less dense than water, it will float.

Meanwhile, you answer this question. Gravity is supposed to be a force thar pulls objects down toward Earth's center (and you like to employ the idea of multidirectional gravity to explain away upside-down water in the souther hemisphere, or just pretend it doesn't exist because "a sphere has no top or bottom", yes it does). So why is it involved in pushing an object up? This is force away from center, or anti-gravity. It is a contradiction of gravity, and an inconsistency in the entire theory.
Gravity pushes things down, but wait except when we use it for a formula to do the opposite. Uhhh okay. Meanwhile, we have to have gravity and buoyancy because we see buoyancy as only related to objects in water, and that people can move in three dimensions underwater doesn't seem to strike us as some kind of pro of gravity, nor that they aren't pulled down like other objects in gravity because they are floating on a raft. Sure, whatever, let's believe all that.

Remove gravity from the paradigm, what do you have? Buoyancy works the same in air as it does in water. The only difference being there are relatively few objects naturally lighter than air. Which is why flight for humans often involves propulsion or momentum as a cheat. We can't simply ride a levirock raft, because levirock doesn't exist.

Ever notice thar the observed pressure gradient seems to be related to altitude?
You mean the weight of the fluid above? Yes, I have. Gravity explains this quite trivially.

Gravity theory has no explanation for why this is.
Pure BS.
Gravity does explain it, incredibly simply.

If you consider a column of fluid of area A, and height h, and assume that for simplicity the density of the fluid and g remains constant, then the weight of that fluid will be given by:
W=rho*g*h*A.
This weight acts on an area of A, giving an increase in pressure of:
W/A=rho*g*h.

If instead density or g varies significantly, you need to do an integral.

So gravity most certainly can explain the pressure gradient, and the results of it.
But buoyancy observations have no explanation (don't pretend it is a theory, when you have no explanation at all).

Instead you want to claim there is no downwards force, yet you then have a pressure gradient trying to push things up which just sits there.

So gravity can explain it, and without gravity (or a substitute) you have no explanation.

And btw, these formulas that use gravity in buoyancy are all dated after Newton, meaning all of them are rubbish.
You not liking it because its destroys your fantasy doesn't make it rubbish.

In conclusion, gravity is not necessary for density and buoyancy. Forces already exist that explain this process.
An understanding of gravity is not needed for observations to be made. But gravity is needed to explain it.

So what's the explanation? Well, each upper layer is less dense than the one below it.
And the question is WHY?
That is due to gravity causing a pressure gradient.
Again, stating an observation about air being less dense the higher you are does not explain the pressure gradient.
Nor does it explain why the pressure gradient depends on the density of the fluid.

Because more dense objects cannot reach a layer of atmosphere lighter than them
Sure they can.
Just look at people lifting bricks into the air.
That is most certainly reaching a layer lighter than them.

But around "water droplets in a bubble in a sphere" we see that the air/water inside the bubble is unable to escape, since they have created a strange ultradense layer, and the less dense outside means the bubble bounces off when it attempts to escape into lower density. No gravity just water difference.
No, what we see is that when they are in free fall, i.e. an environment without gravity able to act to create a pressure gradient, buoyancy falls apart.
It is regular water, nothing special about it.
This shows how important gravity is.

Personally, I prefer this one:


You see the density tower under conditions where the effective value of g is non-zero, with the fluids clearly separating.
But then under conditions of weightlessness, there is no separation.

Once more, no gravity (or something to replace it), no buoyancy.

the formula is outright wrong because it assumes gravity exists
You hating gravity doesn't mean it is wrong.
The formula can actually explain what happens, and also explain why the same effect is not observed in free fall (i.e. weightlessness, where the effective value of g is 0).

Weigh the water.
i.e. measure the force due to gravity acting on the water?

So why is it involved in pushing an object up?
Because gravity creates a pressure gradient in a fluid based upon the weight of that fluid.
And in the cases where the force due to this pressure gradient is larger than the force due to gravity acting directly on the object, the object will rise and the more dense fluid will sink.

It is a contradiction of gravity, and an inconsistency in the entire theory.
No, just your pathetic strawmen of it.
Once more, multiple forces can be acting.
You saying this is a contradiction is like saying if you get a see saw and put a 1 kg weight on one side, having it fall to the ground, and then put a 100 kg weight on the other, gravity is somehow contradicted because gravity is indirectly causing the 1 kg weight to go up.

There is no contradiction at all.
This is entirely expected with the theory.

Remove gravity from the paradigm, what do you have?
Absolutely no justification for why things should fall, nor any justification for buoyancy.
Again, we see this in free fall, where buoyancy no longer applies.

W=rho*g*h*A.
This weight acts on an area of A, giving an increase in pressure of:
W/A=rho*g*h.

More throwing around fake math formulas. I'm not even good at math, and even I noticed from a cursory look that this "formula" inserts gravity in, instead of calculating for material. Further, the way the layers of atmosphere are arranged is in defiance of gravity, which has heavier things hold down lighter things. Based on this model, the most dense layers should be at the top, and the least dense at the bottom. However, that doesn't work, as by definition layers are able to organize based on density.

No. It doesn't In order to explain something, you have to actually use plain terms and not throw around crappy math like Domo-Arigato=rho*b*o*t(sq). Simple comparison. Density of object > density of medium (e.g. water), object sinks. You only have to figure out the density. Something is buoyant if it can be said to have a mass density less than its medium. If you really need this complicated, add through like velocity and momentum and air resistance. But I think it's far more neat if we understand that this is really a simple formula.


Instead you want to claim there is no downwards force, yet you then have a pressure gradient trying to push things up which just sits there.

So gravity can explain it, and without gravity (or a substitute) you have no explanation.

No, that's not true. Why does a fish jumping out of water fall back down? It's because it hits a molecular lattice than basically has a ton of holes in it (air). From water into air, a fish isn't built to fly (aside from the "flying" fish (which actually glides). We humans can dive against buoyancy, as the force takes over only once we stop swimming. But it is clear that we are more dense than air, and mostly more dense than water, except fo r ppl who can float on their belly.

And btw, these formulas that use gravity in buoyancy are all dated after Newton, meaning all of them are rubbish.
You not liking it because its destroys your fantasy doesn't make it rubbish.

No, it's rubbish because it is rubbish. What birds cannot fly? All of them are fatsos. That is, their density has a very real effect on their ability to make loft. Humans, being potentially heavier than an ostrich, nonetheless fly by riding in mostly hollow vehicles. Airplanes were often called "airships" and this is a right assessment, because a jumbo jet weighing in the tens or hundreds of tons shouldn't be able to get off the ground by virtue of the effect gravity has on it. But it can fly just fine.

In conclusion, gravity is not necessary for density and buoyancy. Forces already exist that explain this process.
An understanding of gravity is not needed for observations to be made. But gravity is needed to explain it.

As I already told you, all that is needed for buoyancy equation is to compare object density. A denser medium pushes a light object back up, and a lighter medium pushes are denser object back down. Why? For the same reason a heavier object can push a light object around a table.

Why does a brick in a no gravity flat earth delusion overcome the surface tension of water and friction with the liquid to sink?

Same way any dense object overcomes surface tension. It breaks through the atomic matrix and falls through, being more dense than the medium it entered. Brick is heavier than water so buoyancy and surface tension are not super-big factors.

Btw.

I guess that this term is only meaningful for solids. Liquids change their shape and the resistance to do so is measured by viscosity, not friction. Water has a low viscosity relatively to 'thick' substances like honey
TL;DR the term frictions only applies to solids.

Why do you think .986 is the gravitational amount? Any guesses?
1. The number comes from dividing 360/365 (a circle by a year) not from any actual measurements of gravity. In other words, they needed a constant there, so they made it up, on the spot. Don't believe me? This is the long version. 0.986301369863
2. There's a second reason. What do you get when you multiply a number by one? That number. When you divide by one? That number. How would you make a number look relevant without making much difference in addition or subtraction also? Make a number like one, but slightly under, so if it's a whole number, it just adds a decimal point. So .986 is a mathematically irrelevant number. If you took it out of the equation, it is close enough to one not to mater (even without cross-cancellation). For example, 36/.986 =36.5111561866. And 36*.986=35.496. In most less than a hundred, it barely shifts the original number. Why make a mathematically insignificant number? So that the equation doesn't need it unless you want to insist that someone is not being scientific. It's a tool for virtue signalling. Not something that makes a difference in objects weighing less than a ton (and even then, it's maybe 12-35 or so usually. Golly it was so important that I added .986 into this equation, it made so much difference. This minor difference means no raised eyebrows when someone measures the mass or density and gets nearly the same value.

A constant using a value approaching 1 is someone trying to pull a fast one. They know that if you were to remove the value, you'd get a more rounded (less "scientific") number, so you don't take a hard look at the number, which is designed mostly to add decimals.

I see why you like responding like this.
It allows you to pretend you have addressed everything while ignoring parts of the post which truly expose your BS.

Mmmhmmm. It's easy to tell us that it does without showing any proof.
Again, it comes down to explanatory power.
Gravity provides a consistent system, which explains why things fall, why there is a pressure gradient in fluids, why this pressure gradient is related to the density of the fluid, and why objects immersed in a fluid are pushed up by the fluid, either reducing their weight or making them actually move up.

Conversely you have no explanation at all.

Quote
Pure BS, you say.
If it is pure BS, you need to refute the explanation, not just dismiss it as BS, or dismiss it as throwing around fake math formulae.

So if you want to pretend it is BS, clearly explain what is wrong with it.

If you consider a column of fluid of area A, and height h, and assume that for simplicity the density of the fluid and g remains constant, then the weight of that fluid will be given by:
W=rho*g*h*A.
This weight acts on an area of A, giving an increase in pressure of:
W/A=rho*g*h.

Quote
I'm not even good at math
Then you shouldn't be dismissing the formulae.
But what your problem is far more fundamental, you just hate gravity and will object to it however you can.

Quote
even I noticed from a cursory look that this "formula" inserts gravity in, instead of calculating for material
You mean this formula uses gravity to explain things, as it is intended to do so.
Why wouldn't people start with gravity when they are demonstrating gravity's ability to explain something?

Quote
Further, the way the layers of atmosphere are arranged is in defiance of gravity, which has heavier things hold down lighter things. Based on this model, the most dense layers should be at the top, and the least dense at the bottom.
Just what are you smoking?
Yet again you spout pure nonsense about gravity.
Why should gravity have heavier things on top?
You have no reason for it at all.
If you wish to assert such delusional BS, then explain it. Explain why this should happen.

The formula above shows the pressure gradient.
If you have a compressible fluid such as air, this will result in the air lower down being compressed by the air above.
This more compressed air will be denser than the uncompressed air above, and thus sink.

More importantly, if you put an object inside it, this pressure gradient will act as a force pushing the object up.
Assuming for simplicity an object with a cross sectional area of A and a height of h, then the force will be given by P*A=rho*g*h*A=rho*g*V, where rho is the density of the fluid.

And we know the downwards force is rho_obj*g*h.
So if the downwards force due to gravity is less than the upwards force due to buoyancy as a result of gravity, the object will go upwards.

So gravity indicates that fluids should layer based upon density.
But if you put it in a zero g environment, it wont. Like shown in the video you chose to ignore.

And additionally, you can replace gravity with another inertial force, such as a car accelerating, which results in helium filled balloons moving forwards:

This is because acceleration causes a pressure gradient just like gravity does, which pushes the object forward.

There is no magical layering of the atmosphere just because it wants it.
A force causes that layering.

Quote
However, that doesn't work, as by definition layers are able to organize based on density.
No, they don't.
Instead, gravity and the normal reaction force to it, causes layers to organise based on density.
So your "definition" relies on gravity.
If you put it in a zero g environment, it doesn't.
Just like shown in this video that you chose to ignore:

There is nothing crappy about the math.
But the math does explain it.
Why shouldn't I be allowed to use math?

Quote
Density of object > density of medium (e.g. water), object sinks.
WHY?
That is what you leave out.

You have no explanation at all why this occurs. Gravity provides that explanation.

The answer to why is that gravity creates a pressure gradient in the medium (which must be a fluid), based upon the strength of gravity and the density of the fluid.
This pressure gradient then causes an upwards force on the object, which if you do the math is equal to the weight of the fluid displaced (Assuming g is non-zero).
This means an object will either have its apparent weight reduced by the weight of the fluid displaced, or if that would result in a negative weight, it causes it to move upwards.

This is also important for objects like boats, made of solid steel, where it needs to displace water to float, and if it gets a hole in the hull it sinks.
And where the centre of buoyancy, based upon the shape of the hull and the orientation of it, and the centre of gravity, can play a significant role in the stability of a ship.
Real life sometimes needs things more complex than goes up/goes down.
And you need math to figure out some of that.

Gravity.

Again, you have no explanation.

You have no explanation for why objects fall, you have no explanation for why there is a pressure gradient in the atmosphere which is maintained instead of destroying itself, you have no explanation for why objects can defy this pressure gradient and fall through it.

In short, because you hate gravity, you have no explanation for any of that.

You have no explanation for why an object should fall down, rather than remain in place or go in any particular direction.
Even appealing to the fluid it is immersed in, you have no explanation for why being denser than the fluid should make it go down, rather than remaining in place or going up or to the right or any particular direction, nor why being lighter should cause it to go up.

You mean semantics. Quite different.
Viscosity is effectively friction.

Why do you think .986 is the gravitational amount? Any guesses?
Because you want to spout pure BS about it, as it isn't the acceleration due to gravity at all?
In reality, g is measured, all over the world for a variety of purposes.
These measurements show it has a value which range from roughly 9.78 m/s^2 to roughly 9.83 m/s^2, on the surface of Earth.

You can even measure it yourself, without buying something specifically for measuring gravity.
Instead, buy an accelerometer, the dumber the better (so it can't try to compensate), a 1 directional accelerometer would be best.
Hold it vertically and zero it.
Then flip in 180 degrees so what was pointing up is now pointing down, and measure the acceleration it claims it is experiencing, then divide that by 2.
That is the value of g.

Additionally, this variation causes massive problems for FEers.

With your delusional nonsense, you have no explanation at all for the rate observed, thus no explanation for why the rate remains the same at a particular location (or only varies by very small amounts), while it changes significantly as you move around Earth.
Why should g at the equator be so different to g at the poles?

But a RE, with gravity as an explanation for why things fall can explain it.
Firstly, the rotation of Earth makes g appear less at the equator due to part of it actually contributing to following a circular path around Earth, and due to this causing a bulge at the equator such that it is further from the centre of Earth.

A constant using a value approaching 1 is someone trying to pull a fast one.
Or it is a measured constant with a value of roughly 1.
But you are off by a factor of 10.
But this entirely depends upon what your units are.
It is only 9.8 m/s^2 because we chose m and s as base units.
Those using the imperial system would instead say it is 32.2 ft/s^2.
That is nothing like 1.

So yet again you are just pathetically grasping at straws, looking for whatever BS you can to try and dismiss gravity, because you can't show any actual problems with it, nor can you provide a viable alternative.

You can repeatedly appeal to simple observations, but you have no explanation for them.
