No. You clearly stated that satellite orbits do not change as "proof" that the initial claim was wrong. Now you admit there are changes, some of which cannot be measured/quantified. So, your claim was wrong and changes in orbit could easily be affected by changes in charge along with all the other unquantified effects. The largest is obviously what you say is "disturbances from other planets". That could be conceivably be because of changes in their respective charges. Especially when you consider mass driven obit calculations have consistently failed their 350 year old theory.paladin17 wrote:I didn't say they never change. They do change, and there are plenty of known factors: tidal forces, disturbances from other planets, even solar radiation and solar wind pressure and atmospheric drag (for artificial satellites). What I did claim is that these changes are not caused by a seasonal charging and recharging of the Earth. Even more precisely: I did claim that there is no evidence for changes being caused by this.Aardwolf wrote:The information isn't available for anyone not just me, however, are you still standing by your comment that the moon and artificial satellites orbits never change?
Well, if they don't measure gravity as a whole please explain how are they able to confirm changes are only local and not changes to the whole? You're just assuming the changes are not on the whole planet without any proof at all.paladin17 wrote:They don't measure it. They use an existing model. What they do measure is slight deviations (with respect to the existing model) of the orbits of satellites, caused by local gravitational anomalies.Aardwolf wrote: And how exactly does GRACE measure the gravity of the Earth as a whole? Do you have any idea how this experiment works?
They all drift randomly so what is the "certain manner" you could identify from random fluctuations, and how exactly would you determine the specific cause and isolate from the other causes?paladin17 wrote:If the initial model would be incorrect (say, if the Earth suddenly became heavier), these changes would be a bit more than slight. I.e. the orbital parameters of both satellites would start drifting in a certain manner. Same is true for GPS satellites, geostationary satellites, Earth observing satellites in Sun-synchronous orbit etc. All of them would suddenly feel the increase in gravitational parameter of Earth.
Can't be done. As I said gravity is constantly fluctuating. Anything you read anywhere about gravity is an average. In addition, the IPK is measured against replicas of itself and they all have differing weights over time and they are pretty much clueless as to why. If you knew anything about gravity measurement you would be fully aware of this.paladin17 wrote:BTW, would this hypothetical mass increase affect us here on Earth? Maybe we shouldn't go very far and just measure the weight of something very precisely and see if something changes with the time of year - and by how much.
Interestingly the fluctuating instability of the IPK last for about 30 days after it's cleaned for "unknown" reasons. Clearly they haven't considered the effect of cleaning on the surface electrons. Obviously if the charge of an object was the real factor determining weight then disturbing the electrons would affect it's weight until it stabilises the electron balance again. Of course to suggest this to them would cause heads to explode so they'll have to stick with "unknown" reasons.
