Terrestrial Development

    To open, here is a fact: our local star, commonly called Sol, is pure white and not yellow–a fact that annoys me to no end when reading science fiction.
    A star begins its life as a dust cloud–how did the cloud get there?–at some point the gasses coalesce and several things could happen:
    Not enough matter and you get a gas giant planet like Jupiter
    A bit more and you get a brown dwarf–basically a star that fails to have enough mass for ignition
    Next comes a red giant, as the name says these things are massive–though not actually red.  Over time the outer shell expands while the core collapses under its own mass.  If the physicists have their math correct in some billions of years the red dwarf will explode and collapse–let's face it the math they are using is insane; forget to move a decimal or to carry a one and everything becomes wildly different on top of the fact that the math for a solar system's creation is theoretical in the first place as no one has ever seen it happen.  The explosion will leave a planetary nebula while the collapse will yield a white dwarf within the nebula.
    From my research, physicists expect that Sol will eventually expand into a red giant and engulf our solar system in about five billion years…but what if this has already happened?
    If a white dwarf is the remains of a red giant that went BOOM and Sol is white and roughly the right mathematical size to be a white dwarf there is the chance that Sol has already gone BOOM, left a planetary nebula behind, and that nebula eventually formed a disk of dust, plasma, gas, and various other debris around its equator that over time coalesced into the plants we have now.  As well as explaining the Ort cloud and the planets both within and beyond the Ort cloud as it is probably the furthest extent of Sol’s bloating and subsequent explosion.
    A bit more proof is the amount of Uranium, and Gold we have on Gia (Earth) as these elements are thought to be created inside stars, and it makes more sense for them to have been locally created than to have flown her over cosmic distances and accumulated in veins as they have.  We also have an abundance of lead which is the byproduct of the decay of uranium–I wonder given their similarities if gold is the byproduct of another radioactive element’s decay?
    Pretty much all the other planetary formation theories remain the same but instead of forming from the same dust cloud as Sol we were formed from Sol’s expansion and collapse.  That means over time instead of Sol expanding it will eventually just run out of fuel and become a black dwarf in 10 to the 38th power years from now.
