Perhaps my earlier question was not clearly stated, and in fact, there probably ought to have been more than one question. So here goes…
We know that the Solar system was formed from material that was created by one or more Supernovas because the Earth and other bodies are rich in metals. The creation event(s) must have been quite remarkable because we find elements that are as heavy as possible without immediately decaying into lighter elements. Even in our laboratories, we have not been able to create stable element heavier that we find in the top layers of the Earth’s crust. The supernova(s) that created this material must have been extremely violent to have the energy that created this amount of stable heavy elements. (Can we observe supernova remnants with Uranium, Thorium, etc.?)
Subsequently, a pressure wave went throught the Inter Stellar Medium (ISM) that caused the ISM to condense. That condensed material would have further colapsed due to gravitation attraction. Often I have heard that the material then heated up and formed the sun. I think that is a bit innacurate. Rather, the ISM must cool off first in order to allow gravity to colapse the cloud which if heated would scatter in random directions. Once the density reaches a critical stage, then gravity and heat can balance and form a stable system that can heat up enough to allow fusion reactions to resist the inward pressure of gravity.
OK, so the two questions are:
1) Can we find the core left from the supernova that created the enriched ISM that formed our Solar system?
2) Can we find the cause(s) of the pressure wave(s) that caused the ISM to colapse and condense into a cloud dense enough to let gravity bring in more material and overcome the inevitable heating caused by the energy of the infalling matter?
I know that these are difficult questions and there may be too much complexity for our current knowledge. I’m posing them in order to stimulate thought and investigation.
If you have a cute or clever answer, please save it for a more appropriate venue.
