Planet X is idiotic. The search for every planet in this era was predicated on a prediction made by studying the behaviors and orbits of the known planets.
A simple human error in recording observational data. A search was on for a planet that wasn’t there.
When the error was found and corrected, no planet would have been expected there.
And now this fantasy wont die.
“And now this fantasy wont die.”
Kinda like the fantasy that leftists are humans, when we all know that they’re lizard people from the Zskslszs system (their name for it) disguised with human skin suits.
