Planetary accretion?

<br />I can't see how planets could form from the solar disc as surely any matter present would be swept up into the main body of the proto star?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">There are problems with planet formation from a disk, but being swept up by the protostar is not one of them. Anything with angular momentum (i.e., orbiting) cannot be swept up or get any closer to the star than its elliptical orbit allows. -|Tom|-

Hoping it is helpful to make this comment: the disk accredation explaination of how planets form is just a model and does not in fact reflect real events. The truth is no one knows how planets formed or how anything else formed. It is just models that are being played for all they are worth and nothing more.

Jim, models are made to be invalidated. My own is a case in point. Refer to my foolishness in the Valles Marineris thread. LOL:)!

Honestly I'm more clear on accretion than I am on why planets distribute out with the spacing they have, and why they don't end up in the same orbits. I've read on it, but I honestly haven't fully absorbed it yet.

Correct me if I am wrong but doesn't Bode's Law predict the distribution of the planets using the Law of Gravitation? Several predicted locations eventually yielded discovered planets. Notice (Jim especially since I know how much you hate models) that the distribution is governed by a law, not a theory. That is the purpose of this thread, to hash out hypotheses about why the planets spread out the way they did.
My own question now: Could a star experience overspin and eject material that later accretes according to Bode's Law?

See metaresearch.org/solar%20system/origins/...nal-solar-system.asp (which you have probably seen, but which needed to be referenced in this thread anyway). -|Tom|-
