Thoughts
Planet 9 is so funny to me because it's like a real-life Russel's teapot. Russel's teapot is a thought experiment so you can reject it with
"there's obviously not a teapot" but Planet 9 is a real theory and scientists just haven't been able to prove or disprove it. And I keep expecting someone to know. Like surely even if there's not a consensus there's a "likely" or a "probable" explanation and not this 'well science just can't answer this question, sorry, check back in 10 years.'
