Fermi paradox and Tucker Carlsons claim about not detecting objects coming to Earth

Assuming no coverup, what would we expect to see of the objects that are reported within Earths atmosphere?

Assuming optical reflection, the light detected from a luminescent object falls at the distance squared, but reflected light of an object travelling towards or away from us relying on sunlight falls off a lot faster, so more like 1/r^4. See comment here by u/rocketsocks ” What that means is that every factor of 2 improvement in being able to see dimmer targets only translates to a measly 20% increase in the observability distance for objects in the outer solar system, and it takes a full 16x improvement in sensitivity to be able to see just 2x as far. ” https://www.reddit.com/r/space/comments/v7l1le/could_jwst_observe_oumuamua/

This would make detection of objects that are typical UFO sizes likely very difficult at range.

Oumuamua was about 400 meters long and its got beyond the range of visibility even for the JWST.

If the objects are much faster, then they may not move long enough for us to have much chance of observing them. It appears that most UFO’s are not very luminous since their luminosity is usually only apparent at night, and may be atmospherically mediated.

Despite this, a few researchers think we may have seen orbital distance(?) objects in photographic plates taken prior to the age of man made satellites – Beatriz Villarroel https://www.sciencedirect.com/science/article/pii/S0094576522000480#!

Its also perfectly possible that we can’t see them because they are not visible to us in the long distance part of the travel, for reasons beyond our current understanding, perhaps warping space or being too fast to detect, or via some ability to jump. I couldn’t possibly say, but I also am saying that we overstate our detection abilities for objects entering the solar system.

Additionally, if the object is shaped like a curved cigar or saucer, with precision surfaces, the area that reflects back if it is heading to you in the expected orientation, will be extremely small even if it is a high reflectivity material.
