The moon is receding less than two inches a year. There are many variables that are not factored in. Uranium continues to decay into a stable lead isotope. The existence of great quantities of space dust, which by the Pointing-Robertson effect would have been vacuumed out of our solar system in a few thousand years, indicates the solar system is young. In a closed system this would be true, but the solar system is not a closed system.
Comets bring in new dust.
At the rate many star clusters are expanding, they could not have been traveling for billions of years. There is a repeating cycle of stars forming and collapsing. With the Hubble Space Telescope we can see stars forming. See the picture at the top of this page. Saturn s rings are still unstable, indicating they are not billions of years old.
