When you say “significant” in comparison to a molecule people don’t think that means Jupiter is the next threshold. They think of a spec of dust as the next step (if that).
Do you think this was truly a one off? It is likely such things have happened many times since our solar system was formed. Indeed, it would be remarkable if this was the first one. It is merely the first we have seen. Above people noted the Centaurs which may have come from out of the system. Above is a cite there are billions of rogue planets cruising through the galaxy. Your insistence that extra-solar things bigger than a molecule sailing through our solar system is rare is weird.
Not to mention you inconsistent use of “significant”.
Yeah. We know this. We can see material in our sun that would not be there in a 1st or 2nd generation star. The only way we get all the stuff we see in our solar system is from previous stars that forged new elements and then blew up and seeded vast nebula from which our solar system formed.
So yeah…most of our solar system is from a previous solar system. Probably more than one.
Looks to me, with your italics, that you think my notion that our solar system derived from previous solar systems is wrong…and then you say you agree. I can’t keep up.
Did you miss the words “larger chunks” there? From your posts, it seems you think the solar system is mostly composed of an agglomeration of asteroids and rogue planets spit out by previous generations. When it’s mostly made up of molecular hydrogen.
I’m saying all the material for the solar system comes from the previous generations of stars. But very little of it came in the form of large chunks of matter.
Not “only a large chunk of the matter in the solar system came from previous generations”.
I didn’t use “large chunk” to mean “large proportion of”, I used it to mean “in large pieces” (“large” being subjective, of course, but certainly not asteroid-sized)
