Acceleration is not constant on Earth
« on: July 18, 2019, 06:31:36 PM »
FE theory claims the Earth is accelerating up at 9.8 m/s^2.  The problem is that you can measure a different force of gravity whether you're at the North pole, or Equator.  The acceleration is slighty less 9.780 m/s2 at the Equator, due to centrifugal force of the rotating globe. On the FE, acceleration would have to be the same anywhere on Earth.  Earth cannot be flat because of this.

They claim that "Celestial Gravitation" causes the variation of g with altitude:
Quote
TIDAL EFFECTS
In the FE universe, gravitation (not gravity) exists in other celestial bodies. The gravitational pull of the stars, for example, causes observable tidal effects on Earth.

Q: "Why does gravity vary with altitude"

A: The moon and stars have a slight gravitational pull.

But
  • In my book gravity is gravitation.
  • How the moon and stars can explain a predictable variation with altitude is unexplained.
  • Why g varies with latitude seems inexplicable.

This experiment is uncontrolled. There are no examples of it being performed in a vaccum.

I have already demonstrated that that is completely irrelevant.

The buoyant force, and more precisely, the variation of it, is insignificant for any sufficiently dense object.
Even water is roughly 1000x as dense as air.
That means the buoyant force is only roughly 0.001 x (0.1%) that of the downwards force.
Even if the atmospheric pressure varied by 10%, that would only amount to a 0.01% change in the apparent weight due to the variation in the buoyant force.

So that is clearly not the cause of the much larger (~0.5%) observed variation.

If you instead go to something much more dense like steel, with a density roughly 10000 x that of air, the buoyant force and its variation is even less significant.

You will need a better excuse than it not being done in a vacuum as the air is clearly not an issue.

Air pressure, humidity, air viscosity, temperature, all affect a scale. Scales vary wildly if left uncalibrated. It seems that precision scale manufacturers can't even define exactly how, and just recommend frequent calibration.

Any singular analysis would be insufficient, as there are many properties of the air. Variances in scales can and do occur far greater than the fraction of a degree sought in the experiment. The experiment needs to be done in a vaccum chamber.

The vast majority of that has no effect.
The main thing listed there which will affect it is the temperature as some electronic components will have their properties change with temperature and some mechanical components will also have the properties change.
The air pressure and humidity don't directly affect the scale. Instead they affect the buoyant force. Air viscocity has no effect on the scale and instead is effected by similar things to the buoyant force. You need to calibrate for that to ensure you measure the mass of the object correctly, and even then there are variations due to different objects having different densities and thus different contributions from the buoyant force per unit mass.

But these effects are minor compared to the variation of gravity.

Variances in scales can and do occur far greater than the fraction of a degree sought in the experiment.
What fraction of a degree?
We aren't measuring angles. We are measuring acceleration.

The experiment needs to be done in a vaccum chamber.
No it doesn't. If you want to assert it does you will need to provide evidence of these massive variations.

Again, I have shown the effect of the atmosphere is negligible. The only time it would be significant is if you were trying to weigh a balloon or switched the atmosphere to water or the like.
In order for temperature to be an issue you need to go to quite extreme temperatures, like in a furnace.

So far the only thing that indicates the current experiments are not sufficient are your claims because you can't explain the variations in gravity on a FE.


And of course that ignores the experiments with absolute gravimeters which directly measure the gravitational acceleration.

A vacuum chamber is not needed.  You zero the scale first with air already factored in, then measure the weight of a specific mass.  This effectively throws out any variations due to air pressure or density. 

Can a FEer explain how there is less gravitational force at the equator than at the poles?  Tom, surely this isn't the first time you've been faced with this question.

There are additional factors beyond lattitude that influence gravitational force. There areas on Earth with more density that have a greater gravitational pull.  The nome experiment reflects this.

Some interesting quotes there. The gravimeter is really a seismometer and it is detecting signals in the low frequency band as 'gravity waves' and 'infra-gravity waves' under a theory that gravity would cause variations as picked up by a seismometer. The gravity anomalies seem to be correlated with the seismic zones of the world.

If a 1kg weight is measured with the same precise scale at the same lattitude with the passage of low and high atmospheric pressure and it resulted in the same measurement, you would have to concede that atmospheric pressure changes are not why things weight more at the equator.

Here's the other weight experiment done with a properly calibrated scale measuring at different lattitudes. 



I think you wouldn't accept it anyway, would you?  You still wouldn't be able to explain it.

That is merely a casual version of the weight experiments done 300 years ago. They didn't use vaccumes then and no one is using vaccumes in the present version. The reality of the matter is that a gravity variation would be a violation of the Equivalence Principle which says that gravity is exactly like being on an upwardly accelerating surface with no other gravitating sources around. Many experiments have been tried to detect such violations, from high hights or even from gravity sources such as the Sun, to which they speculate that selective gravity is occuring to maintain the EP through 'preferred curves' in spacetime.

The Weight Variations by Latitude is an ancient hold-over, from before the modern EP experiments. The few types of experiments cited in favor of 'gravity' in these discussions are actually a minority compared to the wide range of experiments which have sought to find violations of the Equivalence Principle without success.

Precision absolute gravimeters are not seismometers!

Absolute gravimeters work by directly measuring the acceleration of a mass during free fall in a vacuum.

Quote
Absolute gravimeters
Gravimeters for measuring the earth's gravity as precisely as possible, are getting smaller and more portable. A common type measures the acceleration of small masses free falling in a vacuum, when the accelerometer is firmly 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:

For the perspective of PHEW FE: The earth is a super huge spacecraft with the current unimaginable speed. (Speed of light is only a dust, compared to UA speed).
The earth breathes due to machinary like mechanism. There are various up and down of altitude in various places and times.

Universal Acceleration is the only strongest candidate to replace the dying gravity theory and be the core of physics.

The current dying physics will have a reliable helper: Universal Acceleration.

If a difference in gravity or gravity variation could be felt from the Sun in an experiment or from the earth in a very long drop test (skyscraper size tests have been conducted) then it wouldn't be like being in an accelerating rocket in intergalactic space far away from any gravity sources. They take that analogy quite literally.

The mining and oil industries all over the globe as a matter of course map areas of interest using a variety of techniques. One of those are field studies that look for gravitational anomalies.
Here is a simple paper on it you may understand.

What is interesting is that it was such a major study that brought about the discovery of the Chicxulub crater in the Gulf of Mexico.

https://www.lpi.usra.edu/science/kring/Chicxulub/drilling-projects/

Im really not sure what point you’re trying to prove Tom, but it’s an undeniable fact that gravity, what ever that that happens to be, is variable across the globe depending on both rock density elevation and latitude.
