Actually that wouldn’t fix anything would it?

No, but they thought they would have their deep underground shelters to go to, then, enslave whomever was left, after the earthquakes, tsunamis, plasma storms and meteor showers caused by the passage, had destroyed civilization, and removed most of humanity (I have always wondered if this is how they get to rule over that 500 million human population).

They are not interested in helping anyone, other than themselves.

the passage would be a celestial event - unstoppable, unless there is tech that can prevent it, or aliens that can nudge it out of the way... who the heck knows.

We can only deal with it when /if it happens. (some of the passages in the past, have not been as destructive, it all depends on the proximity to Earth as it passes.

I have wondered if CERN was their attempt to find a reality where Nibiru does not exist, or passes at a distance.

Indeed.

Last summer (not so much this year), I noticed the portion of the sky directly opposite the sun, appeared as shadowed, darker, as if something in front of the Sun was casting a shadow on that area of the sky.

If this is Nibiru, at some point it will become visible to the naked eye, which will be both a wonderous, and, horrifying sight.
