Q. How can one say, within aaquantum-epistemology, that a discovered
denizen of our soloar system was captured from another star?
A. We turn to the formation of solar system! It grew from a
rotating formation cloud in which gravity constructed various planets at
various distances all rotating in the same plane in the same direction, while
the centre grew in mass, started fusion, and became the sun. Prior to the
formation of planets, a nearby super nova has seeded the cloud with some
post-iron elements.
Empirics?
All the planets are measured in same plane, rotating in the
same direction.
The oort cloud?
Elements past Neptune were too far away and could feel
gravity of near by stars. They collected as a sphere of icy bodies with very
elongated tracks in noparticular plane. We know them as comets!
Retrograde motion?
Some bodies near jupitor in the asteroid belt do not spin
like planets in plane and same direction.6500 do but 100 do not! They are
interesting objects! Most are lkly captures from the oort cloud by Sir Jupiter,
itself a failed star!
Extra-solar?
One retrograde guy is special. Its orbit was computed in detail,
enough precisely that one could project it back 4 billion years. It stayed true
that long! It could not come from oort cloud, it could not have condensed.
That, as Sherlock would say, leaves only capture from nearby star. A plausible
low probability story.
