Stars to Planets
Jeffrey, I don't know if Charles already told you this, but he discussed a similar idea as yours on the Thunderbolts forum a few months ago, maybe last fall. It may be copied on this website somewhere. He came up with his compressive ionization theory as the means by which stars and planets can store energy and gradually release it as electrical energy and so on. I think he figured that stars and planets may also gain mass if they encounter a dense area of space, but generally they should be gradually losing it. So they should be gradually decreasing in size.

Star System Exchanges
Your idea about objects going from one star system to another isn't something I've heard before though, although it's similar to Cardona's idea that the Saturn system, which included Earth, Mars and some moons, came from outside the solar system about 10,000 years ago. He actually thinks they came from the Sagittarius Dwarf Galaxy, which intersects the Milky Way near where we are. I'd like to see what your evidence is for such moving about among star systems.

GTSM? What does it mean? Gyroscopic Toroidal Stellar Metamorphosis?
