comment When will all eight planets in our solar system align?
Never even if they were co-planar.

comment Could there be dark matter black holes?
@questionhang As I've said a 'small fraction of matter accreted into the supermassive BHs (SMBHs) at galactic centres was likely dark', I'd be surprised if its much more than 1%, likely much less.

comment Why is the Solar Helical (Vortex) model wrong?
Nowhere was the (a) definition of vortex used/provided.

The term dark-matter black holes makes little sense, see also my answer.

comment Is it just coincidence that the Moon follows the ecliptic?
I don't think that tides with the Sun will necessarily bring an inclined moon into the ecliptic. Do you have any reference/evidence for this?

comment Is it just coincidence that the Moon follows the ecliptic?
@LocalFluff No, only the total angular momentum is conserved, i.e. the inclination of the combined Moon-Earth system is about the same as that of the (mass-weighted) mean inclination of the pre-Earth and Theia. But the orientation of the resulting Moon-Earth orbit is not contrained by angular momentum conservation (the angular momentum in the relative orbit is tiny compared to the orbit of the Earth-Moon system around the Sun).

comment Could we estimate the age of the universe based on the planar property of the Solar System?
The Solar system formed well after the BB, but, of course, its age (which we can meaure from isotope ratios) is a lower limit for the age of the universe, though not a very useful one.

@William You accepted my answer but didn't upvote it. Why do you think this answer is acceptable but still poor?
