All Cosmological evidence point to clouds of dust and gas which gradually coalesced under the influence of its overall gravitational field. The gravitational field intensified steadily as material condensed, thus hastening further condensation.<quoted text>
Should we gay an old science book about star formation? You know, back when they "knew" the Milky Way was the universe?
Or should we get a newer one, where they "know" more about gravity & hydrogen?
Or should we wait for a future science book where they'll "know" even more?
This condensation produced out present sun, but it isn't likely that it did so in one smooth process. There must have been subcondensations formed so that there was a stage during the formation of the solar system where there were innumerable chunks of icy or rocky material--colliding, gorging, breaking up, recoalescing, and so on, and most of it gradually ending up in the central body.
As the coalescing Sun turns faster and faster, the centrifugal effects that tend to throw outward form the center grow marked, particularly where the rate of turn is greatest--at the equatorial region of the coalescing body. As the Sun progresses toward its formation, it becomes an ellipsoid, with matter jutting far out from the equatorial regions in the form of a thinning sheet.
The matter within this equatorial regional sheet can coalesce to form conglomerations of matter smaller than the central body---conglomerations that will continue to move about the Sun caught in the grip of that body's strong gravitational field and themselves separated by great enough distances from the Sun and from each other to be safe from collisions or near collisions that would alter their orbits drastically. And thus we end with planets circling the Sun.........So, now you know!!!!
