I'm (probably foolishly) going to do itone more time:Suppose you wanted to measure the gravitational constant G, how wouldyou do it? You'd do it the same way Henry Cavendish did it 200 yearsago, you'd use Newton's formula F= √(GM/r) where F is thegravitational force of attraction between 2 lead balls of equal massif you chain one of the balls to the earth's surface and let the otherone swing freely.

?? F=GMM/r^2

Now you'll need to determine the mass of the balls, and you can dothat by noting how fast it accelerates when exposed to a knowncalibration force, for example a force provided by a precisely madecoiled clockspring, but if the energy in the clockspring is half ofwhat it was in Cavendish's day and the inertia of the lead ball isalso half of what it was in Cavendish's day then the value of M youwill write in your lab notebook will be the same as the valueCavendish wrote in his lab notebook. And the amount of time it takesfor the freely swinging ball to hit the stationary ball that you writein your lab notebook will be the same as the time Cavendish found. Sothe value of G that you write in your lab notebook will be the samevalue Cavendish wrote in his.

`So you're equating forces Kx=GMM/r^2 where K is the spring constant in`

`Cavendish's experiment and x is the deflection. Then you halve K and`

`the M's. Then G must double??`

Newton says the orbital velocity of a planet a distance r from the sunis v= √ (GM/r) ,

`So the orbital velocity at the same radius would stay the same...which`

`contrary to my idea that stellar aberration would change. But now the`

`number for G in books has changed. But wait, there's more. Distances`

`are measured by time*SoL, and the speed of light, time is measured by`

`cesium atoms energy levels. So halving energy will double periods and`

`wavelengths and the meter will double. So if G->2G, M->M/2, and r->r/2`

`then v does increase by sqrt(2).`

so if G is the same and M is the same (because the inertial andgravitational mass are always the same) then the orbital speed of aplanet is the same, and the solar system would look the same. Andbecause the gravitational acceleration on the surface of the earth g=GM/R^2 where M is the mass of the earth and R is the radius of theearth, g would still be 9.8 m/s, and force would still equal masstimes acceleration.The one thing both Newton and Einstein agreed-upon is thatgravitational mass and inertial mass are always exactly the same, andthat's why Aristotle was wrong, something twice as heavy does not fallto the ground twice as fast; that's also why even physicist who areadamantly opposed to many worlds and love to badmouth it don't use theargument presented around here that the solar system would becomeunstable. Some around here are arguing in effect that Aristotle wasright after all, an object twice as heavy would fall to the groundtwice as fast and we should just ignore 2000 years worth of progressin physics. Unless somebody says something new that I haven't alreadyresponded to at least twice before (and at this point that seemsunlikely) I'm done with this andGroundhog Day is finally over.John K Clark See what's on my new list at Extropolis<https://groups.google.com/g/extropolis>dgd --You received this message because you are subscribed to the GoogleGroups "Everything List" group.To unsubscribe from this group and stop receiving emails from it, sendan email to everything-list+unsubscr...@googlegroups.com.To view this discussion on the web visithttps://groups.google.com/d/msgid/everything-list/CAJPayv0vqPZ5ZW_myVNeYhnZkNV-t6HUdaoHCKiwu_Ve4PbrhA%40mail.gmail.com<https://groups.google.com/d/msgid/everything-list/CAJPayv0vqPZ5ZW_myVNeYhnZkNV-t6HUdaoHCKiwu_Ve4PbrhA%40mail.gmail.com?utm_medium=email&utm_source=footer>.
