[ WP ] The reason the 9th planet in our solar system , with 10 times the mass of Earth , has never been found , is because it 's the size of a golf ball .

`` There's something wrong here.'' 
 
 Johnson's bloodshot eyes looked up from the computer screen he had been staring at for hours trying to wrap his head around the information it was showing him. 
 
 `` What are you talking about?'' asked his senior, Dr. Sunl. `` Put it up on the overhead.'' 
 
 `` Whatever you say...'' retorted Johnson, allowing his fingers to fly over the keyboard to set up for full display of the projector. 
 
 The wall lit up with what was all over the man's screen. Error messages popping up, warnings and the like with calculations, and an ominous timer that changed from days to months to seconds to years to decades, as if it could n't make up its mind. 
 
 `` What exactly am I looking at here?'' Dr. Sunl asked as he squinted his eyes. 
 
 `` I just ran the numbers again of the anomaly that you asked me to pull up. Something has a massive gravitational pull and it's screwing with Pluto's orbit.'' Johnson explained, running the numbers over in his head. 
 
 `` We already know that, Johnson. Can you tell me something that we do n't?'' 
 
 `` It's worse than we thought.'' the junior continued as if the doctor had n't said a word. `` It's moving. Feeding.'' 
 
 ``... what?'' 
 
 `` Look.'' Johnson pulled up another window on the computer, the projection showing everything that he put down. He ran the numbers, calculated shifting of orbits and the sudden jarring difference in Pluto's orbit of Sol. 
 
 `` It's a black hole. It has to be. I'm calculating that this thing has to be small for us to not have seen it before, and because of its wicked gravitational pull, it has to be either a black hole, or something about to collapse and become one.'' 
 
 `` That does n't make any sense.'' Dr. Sunl dismissed. He did n't want to believe it. If it truly was a black hole that was coming closer, it would spell the end of Earth as they know it. 
 
 `` I'm calculating that it has to have at least ten times the kind of mass that Earth has. And it's... tiny. Absolutely tiny. Why else do you think that we would n't be able to find it after all this searching?'' Johnson spoke, looking up. His eyes widened as his face turned pale white. 
 
 `` What. What is it?'' Sunl retorted. 
 
 `` If it is what I think it is... it's going to collapse on itself. What's the density needed for an object to collapse and become a black hole?'' 
 
 `` Something like six septillion kilograms per cubic meter. Why?'' 
 
 `` Take a look at the kind of gravitational pull this thing is having. It's throwing almost everything out of whack. It'd have to have the pull of something ten times that of earth. And if it's something as tiny as what I'm thinking... then we have our hands on one of the universe's newest black holes waiting to be born...'' 
 
 `` Bullshit.'' Dr. Sunl spat, shaking his head. He rushed over to his own computers, punching in the orbital shifts. He shook his head, falling into his chair. `` Then why has n't it collapsed on itself? If it's that powerful and that strong, and that tiny... would n't it do us all in?'' 
 
 `` No doubt.'' 
 
 `` So then what do you propose, Johnson?'' 
 
 `` Well, what can we do? Take a massive racket and knock it farther? I do n't think we can do something like that.'' 
 
 `` Then I guess.... we just sit here and wait to be devoured by this black hole in the making?'' 
 
 `` I guess so.'' Johnson lamented. A long pause was held between then. `` Coffee?'' 
 
 ``... Sure.''
