Neufer made a very interesting statement during our discussion of why spins and orbits are in the same direction. Allow me to quote Art: "When the solar system was formed it was probably a plasma locked into a constant rotation rate by strong magnetic fields. You cannot ignore the plasma/magnetic field aspects and expect to get the right answers."
I am not disputing this statement. But I desire more details. A cold molecular cloud of dust and gases starts to collapse due to some higher concentrated density gradient. How is the plasma and magnetic field generated ? Certainly a magnetic field can be generated if ions and electrons in a plasma are in motion, but what energy caused the plasma which needs very high temperatures to exist ? How does the plasma become "locked" into a constant rate ? And why is this constant rotation rate required to get the right answers ? This is just a friendly discussion; please don't allow Chris to intimidate you.
Neufer also suggested that the solution lies in the fact that almost all of the angular momentum of solar system lies in the planets themselves. Art, if you have some new idea about why this helps the solution, could you share it. By the way, most of the angular momentum of the solar system is in the orbital velocites and not the rotation spin of the planets. This is indeed for me a big part of the solution.
Art, I am definitely in agreement with you saying that to get the right answers or solution you need magnetism. But which magicians hat did you pull the magnet from ? Maybe I can supply the magic wand for you.
My new friend, Thoth, explained that magnetic fields were strong interior to 1 AU and past 100 AU. I imagine that as the protostar begins to gain energy, it transfers radient energy to the extreme inner part of the disk thereby creating plasma and magnetic effects. How are plasma and/or magnetic effects created at the extreme, cold perimeters of the protosar disk ?
