I can't speak to the scientific value of the paper--actual quote:
We focus on a more exciting possibility: if the OGLE events are due to a population of PBHs then it is possible that the orbital anomalies of TNOs are also due to one of these PBHs that was captured by the Solar System.
But the writers of "What if Planet 9 is a Primordial Black Hole?" get an A for showmanship. Page 5 includes an "exact scale image" of the black hole discussed:

The AI paint name generator (previously) has refined its preferences. Though still very bad at naming paint colors, there seems to be (to my mind) an emerging personality, one that has beliefs and, perhaps, opinions about its creators.
Pictured at the top of this post, for reference, is the human-named classic Opaque Couché.

We can't be far off a time where we can order buckets of paint by punching in RGB color values. The big paint companies could obviously do this, but right now all they seem to offer are elaborate, bloated interfaces wrapping their own marketing-driven color schemes. And I'll grant that the paint pigment gamut might have some very weakly-covered areas, lightfastedness issues, and so on. I hope whoever eventually does this (brand suggestion: LATHEX) also creates a robust API for it and a affiliate program, so that Paint Colors Invented By Neural Network can be tested and refined against thousands of actual purchases.

μcapsmic zooms in on the found at of spray paint caps used to paint a mural of the Star Child from 2001: A Space Odyssey.
Used and naturally clogged in the most random ways possible, these spray paint caps were once indistinguishable from one another to the human eye and untouched by the human hand in the making.
Now, each of them is considered to be small-scale models of the Universe that they created it.
The first part showed here is a selection of six clogged spray paint caps that were used to create the stellar mural "StarChild (Genesis)".

The lovely brown hues in Eugene Delacroix's 1830 painting above, titled "Liberty Leading the People," were actually pigments made from ground-up mummies from Egypt. From National Geographic:

The use of mummy as a pigment most likely stemmed from an even more unusual use—as medicine. From the early medieval period, Europeans were ingesting and applying preparations of mummy to cure everything from epilepsy to stomach ailments. It's unclear whether Egyptian mummies were prized for the mistaken belief that they contained bitumen (the Arabic word for the sticky organic substance, which was also believed to have medicinal value, is mumiya), or whether Europeans believed that the preserved remains contained otherworldly powers.
What is clear to researchers is that early artist pigments were derived from medicines at the time, and were commonly sold alongside them in European apothecaries. And just as mummy was waning in popularity as a medical treatment, Napoleon's invasion of Egypt at the end of the 18th century unleashed a new wave of Egyptomania across the Continent.
Tourists brought entire mummies home to display in their living rooms, and mummy unwrapping parties became popular. Despite prohibitions against their removal, boatloads of mummies—both human and animal—were brought over from Egypt to serve as fuel for steam engines and fertilizer for crops, and as art supplies.
By the beginning of the 20th century, however, the supply of quality mummies for pigment appears to have dried up. A 1904 ad in the Daily Mail requests one "at a suitable price," adding: "Surely a 2,000-year-old mummy of an Egyptian monarch may be used for adorning a noble fresco in Westminster Hall…without giving offence to the ghost of the departed gentlemen or his descendants."
