Nice Pun.
Actually if they could find it, it would explain behaviors we observe but haven’t figured out, like what and why objects are knocked out of the orc cloud on semi regular (if very long periods between) cycles.
Of course one would think if something was out there, its assumed someone would have seen it by now, but that is a long long way away, and there is no guarantee whatever it is, its orbit would be aligned with the other planets, so what angle do you look for it?
I will certainly yield to trained astrophysicists but I think the circumstantial evidence certainly seems to suggest something could be out there.
I think you meant the Oort Cloud. I agree that the periodic ejection of large numbers of comets from the Oort is one indication that there is a large object/planet in a very long orbit.
