Title: UA
Post by: Lonegranger on July 07, 2019, 02:18:08 AM
While there has been much debate on this forum about gravity there has been very little on its flat earth counterpart, UA.

With UA being one of the cornerstones of FE belief it would be interesting to find our why FE believers gravitate toward that explanation of why things fall.

In the FE Wiki on UA, which appears to spend most of its time discussing gravity rather than providing any evidence for UA, provides little or no evidence to convince the reader of the validity of UA.

https://wiki.tfes.org/Universal_Acceleration#The_Basics

According to the WIki:

The are several explanations for UA. As it is difficult for proponents of Flat Earth Theory to obtain grant money for scientific research, it is nigh on impossible to determine which of these theories is correct.

I have to make clear the typo is on the Wiki and not due to my carelessness. The Wiki admits that there is no single explanation for UA and on exploring the Wiki there appears to be nothing in the way of supporting evidence. Though they do include these two experiments that we can all carry out at home!

Experiment 1: Step up onto a chair and step off of its edge while watching the surface of the earth carefully. The feeling of free-fall is the feeling of weightlessness. If you pay attention closely, you will observe that the earth accelerates upwards to meet your feet. Take note of any graviton puller particles or bending space that you observe during the experiment.

Experiment 2: Now find a ball and raise it into the air with your hand and let it go into free-fall. As it does this, as well as before and after, you should simultaneously feel the earth pressing upwards against your feet. This tells us that we are being pushed to be in the frame of reference of the earth, as the earth runs into the ball. Again, take note of any observed graviton puller particles or bending of space that you observe in this experiment.


......and Tom Bishop complains and nit picks the 200 odd precision experiments carried out under laboratory conditions to find the gravitational constant! While he presents jumping off a chair or throwing a ball as a way to prove UA!

It strikes me that the main argument for UA is based not on any evidence that may support it, as there is none, but rather on the grey areas that still exist in relation to gravity, which I am sure you would all agree is a rather feeble starting point.

The question is with so much evidence around to support gravity, why do flat earthers still reject it in favour of  its evidence free counterpart UA? Could it be due to the simple fact that gravity as we know it would  be impossible on a flat world, while UA Is a better fit  with their FE world?

Please discuss.

Thought experiment:

Take an accelerometer, calibrated to zero in empty space, i.e. away from any influence of gravity.

Now place this accelerometer on the ground, on earth. Does it show it is being accelerated and if so, by how much and in what direction?

UA conflicts with the main premise: "Earth is static".

They complain about "mind blowing" speeeds presented by modern cosmology:
30 km/s around the Sun" and 250 km/s with the Sun around the galactic core.

But little less than 300 000 km/s that was reached by now under UA was somehow "much less disturbing". :)

And through what is Earth accelerationg?

Velocity doesn't mean anything unless you also consider what an object is moving relative to. Even in UA, for the observer on the Earth, the Earth isn't moving anywhere close to c. This is an old and tired attack on an old and tired idea.

"Velocity doesn't mean anything" (by itself) - agreed.

"for the observeron the Earth, the Earth isn't moving anywhere close to c." - For the observer on the Earth the Earth isn't moving at all,
whichever model describes it in cosmic refernces. However, the UA would require the Earth to constantly approach c, due to the Relativity theory.
Without that after the Biblical 6000 years under the accelreration of 9.81 m/s2 we would move even faster:

31 556 925 sec x 6000 years = 1.89 x 1011 s
1.89 x 1011 s x 9.81 m/s2 = 1.86 x 1012 m/s
1.86 x 1012 m/s / 3 x 108 m/s = 620 c

"old and tired attack on an old and tired idea" - also agreed. The idea is old and debunked thoroughly by old attacks,
but what other replacement was offered to "gravity deniers"? :)

It should be obvious you are making a flawed argument when you get a result greater than c. And you also aren't stating what the Earth is moving relative to, making the whole thing meaningless to begin with.

In the UA model, the fact that the Earth accelerates constantly would be taken as axiomatic - a fundamental property of the universe. That constant acceleration is not at odds with Relativity.

Ofcourse.

That's why I say:

However, the UA would require the Earth to constantly approach c, due to the Relativity theory.
Without that...

And you also aren't stating what the Earth is moving relative to, making the whole thing meaningless to begin with.

You correctly noticed the reason why I asked "Through what?"

In the UA model, the fact that the Earth accelerates constantly would be taken as axiomatic - a fundamental property of the universe.

Also agreed. Fundamental property of the Universe gives two main possibilities:
- acceleration through movement
- acceleration through "some kind of attraction field or spacetime distortion"

Is there third option?

Acceleration through movement requires enough room for that movement.
(Again that question "Through what?", or as you rephrased it as "what the Earth is moving relative to".)

Acceleration through "attraction or distortion" is in RE model named "gravity".

If there is that third option now is a good place to mentiom it.

Can you?

That constant acceleration is not at odds with Relativity.

Yes, that is why the Relativity is there, to explain why the c is not exceeded.

Acceleration through movement requires enough room for that movement.
(Again that question "Through what?", or as you rephrased it as "what the Earth is moving relative to".)

This send to be the only relevant question to address. For Universal Acceleration, the idea is that everything is accelerating constantly. The thing it's accelerating through would likely be hypothesized to be a higher dimensional space. But it really doesn't matter. What matters is the observation that things fall to the Earth, and from there, arriving at a mechanism that would cause things to fall in that manner. UA does that. And it's got some issues that haven't been addressed in this thread. Going "620c" and having to explain how the Earth would be moving mind-bogglingly fast are not along those issues.
Title: Re: UA
Post by: turtles on July 07, 2019, 11:51:56 AM
Does UA presume that the whole universe is accelerating in the same direction at the same rate? (I guess so otherwise it would just be called "the A")

Is the bit of the universe "behind us" empty as everything has accelerated out of it? Is there plenty of empty universe in front of us?

Is the FE universe expanding as it is in RE physics? If it is, is the origin point of the big bang the centre of "pushing from" for the UA?

We already established that twice, but you do have your right to repeat it.

Ok, I respect your
"Most of the FE here do not promote UA."

But your later comments made me wonder, do you think that in UA model:
- Earth accelerates towards falling objects, or
- falling objects accelerate towards the Earth?

Tom, you're the one who loves accurate experiments to demonstrate if an idea or theory holds water, as you are, I think, a proponent of UA why not explain to everyone some of the experiments that you or other people have conducted and published that demonstrate the possible validity of UA. So far all we have from you is a bunch of words and a rather biased critique of gravity. I don't think the experiment of throwing a ball or standing on a chair demonstrates the necessary scientific rigour.

I think the idea of this thread was to see if there were any actual experiments that have been carried out in an attempt to give any credence to UA. One can think all you want about an idea but sooner or later you have to back that idea up with some hard science.

Gravity, as we all know, has some pretty robust experiments that support it, as well as systems whose functions operate in according to its laws, but as far as I am aware UA has nothing other than a few people who have thought that it might help to explain another idea, the flat earth, that too has no hard evidence to support it. Currently, it looks like flat earth believers have one unsupported idea trying to support another.

Many Flat Earthers such as Tom Bishop use the problems that exist around the theory of gravity as some way of supporting their belief in UA, which to my mind makes no sense whatsoever. If you believe in something like UA then the idea should be able to stand on its own. Currently, I see nothing that supports it.

Sooner or later if you have an idea that is at odds with a well-supported one you have to offer even better evince to support your new claim. The ball is very firmly in the UA believers corner and nit picking gravity does their cause no good whatsoever.

Well, you could at least try to answer the thought experiment, you might find it enlightening. You might even find it gives some credence to UA. Aside from the calibration in empty space, it is a practical experiment.

For the current speed of the earth, the so called 'light speed' is like a dust, even tinier.

With exception of hitting something, there is no limitation and prohibition for a body to accelerate continously.

Firstly while thought experiments can be useful to help visualise an idea, for it to have any real value the the elements within the thought experiment should be known to the thinker and based on some previous work. What you are suggestion is not a thought experiment, it’s more idle speculation.
Have you been into space? How do you know how an accelerometer would function in space, all you could do is guess, and it’s hardly a practical experiment.
I fail to see how this would throw any light on UA, but then again idle speculation is about all there is as far as flat earth experimentation goes.

On the Infinite FE, there is no upward acceleration, there is just simply a force very much like Gravity that makes things fall. JD showed the math for it. Some other ideas are density, pressure, scepti's denpressure, and I'm not sure what others there are. That's just a few off the top of my head that I have seen discussed more than UA. Ski used to argue for UA, but he not here much lately. Tom Bishop is here now, he can share his own thoughts on the matter.

It is actually a fairly simple thought experiment based upon the fact that for a small area, gravity is equivalent to the ground accelerating upwards.
Accelerometers rather than directly measuring acceleration, measure a force being transmitted through the mechanism, which is calibrated to know the acceleration required to produce that force. (With the force itself being measured by some device, such as spring, with a known spring constant).

You also don't actually need to go to space.
Calibrate the accelerometer when it is sideways, so it isn't feeling gravity. Then turn it so it is vertical and it will report an acceleration of roughly 9.8 m/s2 upwards.

A direct measurement of the "acceleration" of Earth using an accelerometer would yield a result indicating Earth is accelerating upwards and thus constitute a direct measure of this acceleration.
Some FEers choose this over gravity as that is what it feels like, that you are being pushed by Earth that is accelerating upwards, and that they don't feel themselves being pulled to Earth by gravity as it acts on the entire body at once, and they haven't done the experiments which demonstrate gravity over highly selective UA or the experiments which show issues with highly selective UA.

It would depend where you were standing, up a mountain, in a deep mine, at the poles or equator or in Canada where there is a large anomaly due to historic glacial melting.
Where would you like to stand?
As you could be standing anywhere I think this should cover everywhere.

But this has nothing to do with experiments that have been done to prove UA. Accelerometers confirm how gravity varies over the surface of the planet, and are one of the many factors that tend to disprove UA.

I’m asking what experiments have been done to prove UA other than standing on a chair or throwing a ball?

Variation with latitude for sure.
Weight is only way to measure gravity.
The simple fact is if objects falling was just being caused by Earth accelerating upwards, Earth would have been torn apart long ago.
That means either way you need some unfelt "spooky action at a distance" to explain it.
Either by the highly selective UA somehow accelerating the objects, or gravity, or something of the like.

Absolute gravimeters
(https://ipfs.io/ipfs/QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco/wiki/Gravimeter.html)
Absolute gravimeters, which nowadays are made compact so they too can be used in the field, work by directly measuring the acceleration of a mass during free fall in a vacuum, when the accelerometer is rigidly attached to the ground.

The mass includes a retroreflector and terminates one arm of a Michelson interferometer. By counting and timing the interference fringes, the acceleration of the mass can be measured. A more recent development is a "rise and fall" version that tosses the mass upward and measures both upward and downward motion. This allows cancellation of some measurement errors, however "rise and fall" gravimeters are not in common use. Absolute gravimeters are used in the calibration of relative gravimeters, surveying for gravity anomalies (voids), and for establishing the vertical control network

Evidence for UA is here and here:
https://wiki.tfes.org/Evidence_for_Universal_Acceleration
https://wiki.tfes.org/Variations_in_Gravity
Where?
Variations in gravity doesn't even discuss UA.
The closest you get is the equivalence of gravitational and inertial mass.
But that is expected by relativity, where gravity is the result of curvature of space time.
This also matches with the feeling of free fall.

The absence of a mechanism for gravity is not evidence of UA.
Firstly, gravity is a fundamental force of nature and it has a "mechanism" as much as any other force.

UA on the hand is not. Earth accelerating is not a fundamental force of nature, yet has absolutely no mechanism or justification provided for it by UA.
Pretending you have a mechanism by pretending Earth accellerating upwards is a mechanism is just distracting from the fact you have no mechanism.
That is worse than saying gravity is the mechanism.

Talking about the equivalence principle is not evidence for UA.

The closest you seem to get to evidence are your 2 tests of you falling and dropping a ball, but you just state the way you want.
A straightforward analysis is that Earth appears to move towards you, accelerating up to meet you while you are stationary, and that the ball accelerates downwards while you are stationary.
All it really measures is relative motion.
You know that in exp1 you move relative to Earth and in exp2 the ball moves relative to Earth.
We cannot see that Earth moves upwards, just that there is relative motion.

The absence of any feeling from gravity in free fall is exactly what is expected, and the exact same reasoning can apply to other fundamental forces.

Gravity doesn't need a power source. It isn't just dumping in an unlimited amount of kinetic energy. There is gravitational potential energy, which can be converted to other forms of energy.

Your addendum is also wrong.
Gravity does not behave exactly like Earth accelerating upwards.
Objects falling do.
Earth accelerating upwards doesn't explain why Earth orbits the sun, or the moon orbits Earth, or satellites orbit Earth or the variations in g across Earth, or gravitational attraction between other masses.


So where is the evidence for UA?
So far all I have seen is UA can explain why things fall just like gravity can, and you don't like gravity.

Your pulling my leg again Tom, that’s just empty words you have linked too. Proof is based on experimental data derived from a carefully controlled experiments that can be repeated by anyone that yields the same results.

You complained about the 200 plus experiments that all that proved attraction between masses as the theory of gravity predicts, admittedly there was a very small variation in the numerical results, not the ten times you claimed.......however enough of gravity as this thread is to shine the light on the case for UA, which looks like has nothing whatsoever to support it.you have been unable to provide any information on any data that would support it, all you have been able to link to is some random words of a-flat earth Wiki........hardly convincing is  it.

If the UA is "universally" accelerating, why isn't it accelerating me? I'm definitely being pulled down to the ground with a force of 1g. If I was being universally accelerated at the same rate as the ground below me, I'd just be hovering next to the ground.

If it's just the ground that's being accelerated, the ground should weigh nothing, I could pick up tons of it with my hands (albeit, slowly. We still have inertia on the flat earth, don't we?).

It's not idle speculation, it's about measuring the accelerating forces acting on an object on earth. The point about calibrating the accelerometer in empty space is that it should read zero when not accelerating, that's all.

Now, would you care to say what you think such an accelerometer would read on earth?

It would depend where you were standing, up a mountain, in a deep mine, at the poles or equator or in Canada where there is a large anomaly due to historic glacial melting.
Where would you like to stand?
As you could be standing anywhere I think this should cover everywhere.

I wasn't really asking for a precise figure. It's the direction that is relevant.

You're not being pulled down to the ground, you're being pushed up by the ground.

Under General Relativity (which is the basis for the UA idea) there's no 'force' of gravity. The ground is forcing you to deviate from your natural position which is to stay where you are:

Well, briefly, because it's not really UA that's going on here. Sure, everything on earth is being pushed upwards but that's because the curving of spacetime by the earth's mass means that 'standing still' would mean moving downwards relative to the ground (like the ball and feather in the video). So the physicality of the earth pushes everything out of the way.

A falling object has no force on it so it obeys Newton's 1st law and doesn't accelerate. An object on the ground does experience a force from the ground and accelerates upwards.

Yeah, I get what you're saying, the flat earth is effectively a rocket accelerating at 1g. So what do you imagine is under the flat earth accelerating it? Why doesn't the sun and moon fall down?

Sorry if I've misled you but, no, I don't go along with the whole UA thing or a flat earth etc. I'm just pointing out that the idea of the ground accelerating upwards isn't so silly, in fact it's mainstream science, allowing for the fact that it needs to be thought of in terms of spacetime and not just space.

Now you know that’s not quite true as the reading would depend on where you happened to be standing. However what has that got to do with UA on a flat disc. The problem is the two are interwoven and have to be taken together.

Light blue shifts or red shifts when traveling upwards or downwards in the same manner as if the earth were accelerating upwards. When the photons on the floor travel upwards the ceiling is moving away and the light red shifts, and when the photons on the ceiling travels downwards the floor is moving into the photons and the photons blue shift. Just as would happen if the floor were accelerating upwards into the photons.

See this blueshift and redshift of light diagram which shows how light red shifts or blue shifts when motion is involved and it is approaching or receding from you.

That is not evidence for UA - it is simply not inconsistent with UA.

But you conveniently omit the rest of Einstein's Theory of General Relativity in which mass, including the mass of the earth, curves spacetime (note not just space but spacetime).

And that curving of spacetime (mainly the timelike component) causes gravitation that acts as though mass attracts mass.
So under UA, if you accept all of GR, you have both gravitation and UA - so either you are doubling up or do not need UA.

Worse still for your Flat Earth is that Einstein's GR, acting exactly as Newton's gravitation, would collapse your flat earth into a sphere!

What you are forgetting Tom all the calculations and thought mr E. Put into SR and GR were done on the basis of a spherical earth orbiting a sun at 93million miles, along with-all the other cosmological things you deny. Cherry picking is not allowed.

The solar system you claim would require the calculation to be done from the square one going back to first principles. What you claim is a very different ball game with very different rules. Trying to graft GR or SR on to your flat earth just won’t work.

If you want to show evidence for UA you will have to go back to first principles, and imsure you will find no help in the bible for that.

If all of his works were from others why didn't those "others" present:
     ON THE ELECTRODYNAMICS OF MOVINGBODIES By A. EINSTEIN June 30, 190 (http://hermes.ffn.ub.es/luisnavarro/nuevo_maletin/Einstein_1905_relativity.pdf) otherwise called Einstein's Theory of Special Relativity and
    The Foundation of the General Theory of Relativity By A. EINSTEIN (https://www.academia.edu/375613/Einsteins_Original_Paper_on_General_Relativity).

Had Albert Einstein plagiarised either of those documents there would have been a tremendous outcry at the time especially as both were quite against the "mainstream science" of the time.

And Einstein was an extremely successful student - please show contrary evidence, not just your empty words.

But yes, probably more of Nikola Tesla's work should be taught in schools but that would not help you flat earth or denial of gravitation in the slightest.

Nikola Tesla firmly believed in the Globe earth, the Heliocentric Solar System and the Cosmology of his time.
He was, however, very opposed to Einstein's work because he believed, incorrectly, that Einstein destroyed the work of Isaac Newton. Have a look at:
What I can't work out is why Tesla seems to be held up as a hero by so many flat earthers.  He certainly did not believe the earth to be flat or stationary!

See this address by him: HOW COSMIC FORCES SHAPE OUR DESTINIES, ("Did the War Cause the Italian Earthquake") by Nikola Tesla (http://www.tfcbooks.com/tesla/1915-02-07.htm) in which he states:

For the sake of simplicity we may assume that the earth's axis is perpendicular to the ecliptic and that the human automaton is at the equator. Let his weight be one hundred and sixty pounds then, at the rotational velocity of about 1,520 feet per second with which he is whirled around, the mechanical energy stored in his body will be nearly 5,780,000 foot pounds, which is about the energy of a hundred-pound cannon ball.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
The sun, having a mass 332,000 times that of the earth, but being 23,000 times farther, will attract the automaton with a force of about one-tenth of one pound, alternately increasing and diminishing his normal weight by that amount

Though not conscious of these periodic changes, he is surely affected by them.

The earth in its rotation around the sun carries him with the prodigious speed of nineteen miles per second . . . . .

From the above address.
I have also read, though I cannot verify it right now, that one reason Tesla disliked Einstein so much is that he believed that  Einstein destroyed "Newton's gravitation".
From what I can gather, Tesla did not deny Newton's Law of Universal Gravitation, just differed with Einstein's "curved spacetime" explanation of it.

Sure, Nicola Tesla had a lot of "different ideas", but he most certainly did not believe in a flat stationary earth.

And many of Nikoa Tesla's inventions specifically mention and picture the Globe.

Look here and learn all about the "Real Nikola Tesla":
Quote from: Frank G. Carpenter
Tesla universe INVENTIONS OF TESLA (https://teslauniverse.com/nikola-tesla/articles/inventions-tesla)

Mother Earth Put to Work.
“By this invention every live part of Mother Earth's body would be brought into action. Energy will be collected all over the globe in amounts small or large, as it may exist, ranging from a fraction of one to a few horse power or more. Every water fall can be utilized, every coal field made to produce energy to be transmitted to vast distances, and every place on earth can have power at small cost. One of the minor uses might be the illumination of isolated homes. We could light houses all over the country by means of vacuum tubes operated by high frequency currents. We could keep the clocks of the United States going and give everyone exact time; we could turn factories, machine shops and mills, small or large, anywhere, and I believe could also navigate the air."

Transmission of Intelligence.
One of the most important features of this invention,” said Mr. Tesla, “will be the transmission of intelligence. It will convert the entire earth into a huge brain, capable of responding in every one of its parts. By the employment of a number of plants, each of which can transmit signals to all parts of the world, the news of the globe will be flashed to all points. A cheap and simple receiving device, which might be carried in one's pocket, can be set up anywhere on sea or land, and it will record the world's news as it occurs, or take such special messages as are intended for it.
It sure looks as though Tesla believed the earth a Globe.

Tesla may have begged to differ from your assumptions. And it seems you have been out-tesla-ed.

Nikola Tesla Quotes:

"A single ray of light from a distant star falling upon the eye of a tyrant in bygone times may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes in Nature.”

From: "On Light And Other High Frequency Phenomena" A lecture delivered before the Franklin Institute, Philadelphia (24 February 1893), and before the National Electric Light Association, St. Louis (1 March 1893), published in The Electrical review (9 June 1893), p. Page 683; also in The Inventions, Researches And Writings of Nikola Tesla (1894)


"He will be able to call up, from his desk, and talk to any telephone subscriber on the globe, without any change whatever in the existing equipment.”

From: On the Wardenclyffe Tower, in "The Future of the Wireless Art" in Wireless Telegraphy and Telephony (1908)

There are a bunch more Tesla references to a 'globe', but I'm too tired to copy and paste them all. Look them up for yourself if you have questions.

Tesla, Tesla, Tesla

"Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely IMPOSSIBLE ..Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has NO RELATION to reality. The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories. The scientists of today think deeply instead of clearly.

"The theory, wraps all these errors and fallacies and clothes them in magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king. Its exponents are very brilliant men, but they are metaphysicists rather than scientists. Not a single one of the relativity propositions has been proved."

“Earth is a realm, it is not a planet. It is not an object, therefore, it has no edge. Earth would be more easily defined as a system environement. Earth is also a machine, it is a Tesla coil.

For his wireless energy distribution Tesla calculated Spherical Capacitor between Earth and Ionosphere.
He calculated resonant frequency and designed harmonic resonant circuits to pump the capacitor.
Receiving parties would have their resonant circuits on their side.
(J.P. Morgan stopped the project because he wanted the system in which he could measure and charge for the delivered energy.)

Another Tesla's idea was to create ring around the Earth like Saturn's rings to illuminate the night side of the globe.

This and more surely shows that Tesla knew the real shape and size of our planet.

I recently started a thread on Neutrinos. I think they are an absolutely fantastic particle to answer many of these questions with.

No, I would say that almost certainly you are the one lying, or just repeating a lie.
Just where did Tesla allegedly say this?

Looking for your site, I see no indication of the 2015 date.
Instead I find a few results from debate.org:
https://www.debate.org/forums/science/topic/87964/ from the 1st of June 2016.
https://www.debate.org/debates/The-Earth-is-more-flat-than-it-is-spherical./1/ from the 14th of May 2016.
And the one you provided in the image without a link:
https://www.debate.org/opinions/concerning-the-flat-earth-theory-can-you-prove-your-living-on-a-round-earth

With no clear indication of date.
So I needed to resort to using the wayback machine.
The page did appear in 2015.
But that quote wasn't there from the start.
The first snapshot it appeared in was this one from 3rd May 2017.
https://web.archive.org/web/20170503220010/http://www.debate.org:80/opinions/concerning-the-flat-earth-theory-can-you-prove-your-living-on-a-round-earth

In the snapshot prior to that, on December 31st 2016 it was no where to be found.
https://web.archive.org/web/20161231043512/http://www.debate.org:80/opinions/concerning-the-flat-earth-theory-can-you-prove-your-living-on-a-round-earth

That means it showed up there some time in 2017, not 2015 like you claim.
A page being created in 2015 doesn't mean all the content on it was.

So thanks for once again showing your dishonest double standard.
Whenever you find anything that you think can prop you up, you just accept it, with no scrutiny at all.
But when something shows you are wrong you dismiss it as fake regardless of how strong the evidence supporting it is.

But perhaps the best indication that the quote is not from Tesla is the name.
I have never heard of Tesla calling them Tesla coils.
They were high voltage transformers, or transmitters.

Slight variations in gravity due to other forces are no big deal across the surface of a planet. But slight variations in acceleration across the surface of Flat Earth would be catastrophic. Even a difference in acceleration of a few millimeters per second squared would add up to dramatic terrain changes in relatively short order.

If it's distortion in the UA, then yeah. But not if there is UA + another force at work that is the underlying cause. The thought experiment that at least helps illustrate the concept (even though it's obviously not a real world solution) is an elevator in a vacuum, accelerating upwards at a certain rate. It has 2 1kg blocks on board - one wood, one steel. There's also an electromagnet at the top. When the electromagnet is turned on, suddenly the measured acceleration acting on the two blocks is different, even while the elevator has a constant acceleration without breaking apart. Again, that's meant only to be illustrative of a situation in which something can be accelerating constantly, with varied measurements of a force like gravity, and doesn't explain any underlying mechanism for how there are measured variations in gravity across the surface of the Earth, but I only want to illuminate that those varied measurements don't necessarily immediately result in dramatic/catastrophic changes in the landscape.

That might change the rate at which an object reaches the ground(the ground reaches the object) or the force acting on an object, but gravity(or some other force) should not interfere with the measurements of the Earth's acceleration unless the unknown force is actually interfering with the Earth's acceleration. In which case, the same catastrophic results would occur.

In some older thread Ski and few others mentioned "Celestial Gravitation".

But:
If there was Dome or something like that then its mass would attract objets below it and make them less heavy closer to the Dome they go.
That Dome would not have the shape of the dome.
It would have to be lower at the Equator and higher at the Poles (North Pole and Ice Wall).
That way it would, by own attraction upward, make objects at the Equator lighter for (9.78 - 9.83) / 9.83 = 0.0051 = 0.51%.

If that was the case, the dome would have to have more complex shape than that and conveniently have lower parts right above existing high mountains.
With those lower parts in place above mountains the Dome wouldn't be allowed to rotate.

And why would some masses attract each other and some others wouldn't?

(If it was magnetic force it would differ between aluminum, iron and lead.
If it was electrostatic force it would attract plus and repell minus (or vice versa).
And both of those forces are much stronger than gravitation.)

Background question still remains: Is the Earth static or not?

Is "the firmament" firm? :)

I’m not sure what a vacuum has to do with this. But from the wiki link you referenced it states:

"One precision scale manufacture lists many factors which can affect a scale:
Factors That Can Affect Your Scale’s Accuracy
  “ Differences in air pressure – Scales can provide inaccurate measurements if the air pressure from the calibration environment is different than the operating environment. ”
If the air pressure from the calibration environment is different than the operating environment, it will effect the scale. Also listed on the page are temperature and humidity which can affect the operation of a precision scale.
"

That precision scale manufacturer cited in the wiki (Arlyn Scales) goes on to to say:

"Precision weighing scales by Aryln Scales eliminate the common errors that can be found when using mechanical scales or even less capable digital scales. These scales weight measurement is altered by local gravity. This is an issue that can be avoided when using the Ultra Precision Scales and the included calibration capability.”

https://www.arlynscales.com/ultra-precision-scales/accurate-precision-scales/

So it appears that even the folks you cited take into account and calibrate for gravity variances.

Why need the measurement be "conducted in a vacuum chamber"?
In a simple weight measurement, the only effect of the atmosphere is buoyancy.
Air has a density at sea-level of 1.225 kg/m3 and stainless steels about 8000 kg/m3 and all that matters is the change in density of the atmosphere.

But, in any case, precision absolute gravimeters do measure gravity by measuring the free fall of a mass in a vacuum!

I already posted this:
Absolute gravimeters, which nowadays are made compact so they too can be used in the field, work by directly measuring the acceleration of a mass during free fall in a vacuum, when the accelerometer is rigidly attached to the ground.

The mass includes a retroreflector and terminates one arm of a Michelson interferometer. By counting and timing the interference fringes, the acceleration of the mass can be measured. A more recent development is a "rise and fall" version that tosses the mass upward and measures both upward and downward motion. This allows cancellation of some measurement errors, however "rise and fall" gravimeters are not in common use. Absolute gravimeters are used in the calibration of relative gravimeters, surveying for gravity anomalies (voids), and for establishing the vertical control network

Typical absolute gravimeter:

Your claiming its being gravimeter does not magically gravity exist. You can call it gravimeter, weightmeter or angelmeter does not make any of them exist.

Gravity measurements show that gravity varies across the earth's surface.

That fact all by itself rules out UA.  There's nothing to discuss.

Since this is a "fact" then you should be able to point us to where these experiments have been conducted in a vaccum chamber.

See: https://wiki.tfes.org/Weight_Variation_by_Latitude

Oh no, you're linking to another rubbish article on that tfes website again. You really need to stop using it.

Explain how air pressure effects scales.

Even electronic bathroom scales are made to not be affected by humidity.

Why a vacuum?
All it not being a vacuum requires is that you take into consideration buoyancy and drag.
With an appropriate setup (e.g. something dense) then buoyancy can be quite negligible, and more importantly, variation due to variations in the atmosphere are even less significant.
For example, if you take a steel ball, with a density of ~8000 kg/m^3, with air having a density of roughly 1.2 kg/m^, the buoyant force amounts to 0.015%.
If you vary the atmosphere by 10 %, which is very significant, that would result in a 0.0015% variation in weight.
Yet gravity is know to vary by about 0.7%.
Buoyancy just can't significantly contribute to that massive variation.


You have already been provided with details on absolute gravimeters.

Again, stop to talk about anything isn't exist. No need to buoyancy at all. If the specific mass of one object is higher than the other, it moves down, and if it slighter than other then moves up. no additional force is required. Buoyancy fraud is the result of the desperation of popular science. You are repeating same fraud proves you have cornered and need to fraudments one more time.

Why do you have a problem with buoyancy? It's not incompatible with a flat earth with either gravity or UA is it?

Its having or not having a problem with any model isn't my problem. The problem its being absent. No need to it. I am against all forms of fraud. Throw out of your globularist mind, Come out of your cave and deny the buoyancy fraudment.

Archimed defines the heavier object is how moving down. The force described here is not buoyancy.

I have denied the flights which are fraud. some flight times are in contradict. in this case, you compare them to see which is correct. I compared. The route was contradicted by thousands of different routes, and the evidence was examined before it was completely erased. and it appears that these flights are fake and absent. and those fraudsters were asked to prove these flights. received response: "we do not have to prove anything". Then I don't have to accept your lie. This is completely honest.

Surely you must have had some other parameters for selecting which flights to exclude besides the data not fitting your expectations. That would be shockingly unscientific.

The only justification you have for dismissing them as frauds is that they show your map is wrong.
There is nothing wrong with their flight times.

The problem its being absent. No need to it
It has been repeatedly shown to be real and you have no rational objection against it.
So that clearly isn't the problem.
Buoyancy is very real and you ignoring it doesn't magically make it go away.
But if you want, go ahead and ignore it and tell Tom that his argument is garbage because buoyancy isn't real so it wont have any effect on the measured gravity of Earth.

Nope. You're lying again, again and again. prove this. I've explained all the null so called flights when I did it. And all was logical and none of them was about its doing anything wrong. If I would thought they were true, I would correct the map based on this information.

You've been here for years, and you're objectively objecting to everything. Have you ever cause one believer give up  to this belief, or have you made them think about anything as you think it? No. on the contrary, those who believe in global theories and come here, see the globalists who object to everything like you and begin to give us the right. Your objections are completely null in our mind. because you are too ignorant to be compared to the people you really argue with. and this ignorance increases the faith of the people here.

Either give up or go away.
