High school experiments with centrifugal force are NOT
scientific, nor do they in any way measure the equality in
forces! You HAVE no data on the equality of forces between a
planet and its sun. What are the differences between the high
school experiment you describe and planet revolutions, and why is
this non-scientific? 1) In the high school experiment gravity is
pulling to the side, not the center, 2) the centrifugal force is
continually reinforced by pulling from the student's arm, 3) the
pulling by the student's arm is not measured, 4) the simulated
gravity attraction of a sun is done by a string that is fixed and
cannot reflect variability.
You complain about OUR lack of dealing with facts, Greg, and
then use this example to bolster you claim that Newton explained
all adequately! Get a grip!

What does the price of tea have to do with any of this? We
described an experiment in a vacuum chamber, where a centered
object, spinning was dropped and the centrifugal force measured
precisely as it did so. What you call the centrifugal force DIED
as it dropped, without friction from air pressure to use as the
usual standard excuse. This means that Newton's balanced equation
was a DESCRIPTION of what he saw in the heavens, not an
explanation for what was happening, regardless of how detailed
his description is.
Address THAT, not the price of tea.
