 There has been fuss about this interstellar object passing through our solar system. We know it is interstellar because it dropped from above the solar disk. Everything in our solar system is near the disk. This dropped from above then changed direction at the disk near the sun and went skittering off along the path of the disk.

Why did it change direction? The two reasonable explanations are outgassing from the object and solar wind. The sun produces heat and radiation so one of those must have moved the object. But the object doesn’t change direction until it reaches the solar disk. Why wouldn’t heat or radiation move the object earlier? The explanations given are unsatisfying. Aliens are suggested.

It looks like it bounced. It bounced near the sun on the disk. Why did it bounce on the disk? It looks like it hit something and changed direction. What could it have hit?

The man on the stair. Something that isn’t there. Sounds like dark matter to me. Dark matter varies in density. Play with corn starch suspended in water, it bounces your fist when you hit it and lets your fist in when you touch it. Sticky dark matter sings better than modified gravity theory. Particularly with a bounce. Sticky dark matter, composed of neutrinos, neutrons, whatever, varying its characteristic with its density should explain the disk, rings, moons and belts.
