Is the Sun’s position in the Galaxy close to its predecessor’s position?

    Since nebular theory states that our solar system formed from the gravitational collapse of a giant gas cloud.

    Could this giant gas cloud be the remnants of its predecessor’s nova?

    Most likely. A lot of the initial elements that were used to form our solar system in the first place were remnants of older, more massive stars that went nova/supernova. Another possibility was the gas cloud could've just been leftovers of some other stars forming, but I doubt that. I'd go with your assumption being right, but someone correct me if I'm wrong. (:

    Thanks for replying Calluuuum

    I have seen that some believe that the solar system is the product of 10 supernovas that happen ~6 bya. Personally, considering the vast distances (light-years) between stars, I find this statement very unlikely and difficult to put credence in. That is why I conjecture that our solar system is the product nearby red giant that went supernova >5 bya and then condensed into our solar system.

    Actually, I was thinking of coining term 'oscillating star' similar in idea to oscillating universe.

    The solar system IS the remnant of at least 10 supernova that occured over the last ~6 billion years. Google on cosmochemistry.

    Hi Chronos

    I did Google cosmochemistry, didn't find anything yet about 10 supernova; however, I did found the following theory at http://www.physorg.com/news167302986.html" [Broken]

    In the comment section there is the following reply to a previous question

    I will continue the Google search
