NASA will land a probe on the surface on planet 9 only to find that the entire thing is made of unsold carts of the Atari 2600 E.T. game.

It's your mother

Well I mean at this point it's a meme, and will continue to be so until somebody actually finds the damn thing.

Nope. MOND is not the answer. It is never going to be the answer. There are too many things that MOND cannot explain. One of the reasons why planet 9 was hypothesized to exist is because the orbits of objects far from the sun are out of plane in weird highly elliptical orbits not explainable through modification of gravity's effects at small force scales. Dark matter is another phenomenon MOND was meant to explain away but cant. i.e the bullet cluster is an object with less than 1% of its mass accountable by visible matter. MOND cannot make up the difference. Structures like this are only explainable if dark matter actually exists. The best MOND can hope for is to account for some but not all, of the discrepancy.
