But that's not possible since the system lacks the necessary heavier elements. Our solar system is a 2nd or 3rd generation system, so we have enough heavy elements like C, N, O, Fe, etc, to form rocky planets. This ancient gas giant is part of a system that is almost certainly 1st generation - as the article states, pretty much only H & He.kojikun wrote:I think he means that if the solar system its in is that old, then there could be equally old earth like planets.SyntaxVorlon wrote:Only if a civilization can be created in a nearly pure hydrogen environment, if not life at all.BlkbrryTheGreat wrote:Actually, now that I think about it, I'll be pretty suprised if there aren't at least a few.
Elements heavier than H & He are almost exclusively created in stellar cores, so you have to have at least one supernova before those elements are available. (White dwarfs don't spread the love much.)
