So I guess the large size would have permitted it to smuggle stuff into the core that would have just vaporised in the corona if carried by many smaller objects?
- monster_truck 2mo agoSounds reasonable to me. But also what the fuck happens to the core of such a planet when that happens? We aren't actually sure what gave our core the spin it has, right? I'm not fully awake yet but I think it's plain where I'm going with this.
- andrewflnr 2mo agoIt's not plain to me where you're going. But the answer about the core of a planet engulfed by the sun is that it vaporizes eventually, just not right away.

- monster_truck 2mo agoNo we aren't. That's a theory that barely fits the lower bound of what we estimate the spin of the core to be
