It was unfair. What I did not say, is that the G constant we use on the earth is NOT the true value of the G constant, just as the speed of light near the earth is NOT the true speed of light in a vacuum. How else am I going to squeeze in:

we have to factor into the equation a new property of space: It takes less time to negotiate a linear fraction of space near Saturn than it does the Earth’s distance from the sun. This is further complicated by the use of light, which is also moving faster, as our measuring stick. More, later.

Find me matter in a true perfect vacuum, and we can sit down and calculate the baseline value of G & c. Or we can extrapolate between the Earth and Saturn, and predict something close. We can also calculated the effect the mass of the Sun has on 'space', and use this in the future to properly predict the masses and densities of the planets. No more yellow "water ice" rocks.
And unless and until someone can come up with another reasonable explanation for the optical density on the surface of Titan, the small variance in the speed of sound during Huygens descent, the mystery roll of Cassini, and Huygens' thermal blanket sitting on the surface of Titan a few meters from where Huygens landed, that is just the way the universe is going to have to stay. |
I understand all now. G (and aparently c) are constant, it's just everything else that varies. You had me worried for a moment but we'll make 100 pages yet
