8. SMBH Speed-dating

If supermassive black holes were at a speed-dating event, they'd skip the small talk and go straight to business: these astronomical heavyweights aren't formed by smaller black holes playing the dating game and merging together, but rather through direct gas cloud collapse or a less-than-romantic mass accumulation over eons! Who knew that these cosmic beasts could be so non-dramatic? : The simple fact is, every large galaxy has a supermassive black hole in its midst, and they have masses up to billions of times that of the Sun; failing fickle courtships and comet-swaps, it's the slow-and-steady, gassy growth that takes home the crown.

9. Cosmic DJs Remixing Gravity

Black holes: the cosmic DJs spinning records out of spacetime. They don't just remix gravity; they make it wobble and wave when they join forces on the dance floor: In a groundbreaking model incorporating nonlinear gravitational wave propagation effects, researchers discovered unique frequencies and interactions when black holes collide and merge. This could eventually lead to better testing of whether general relativity is still cutting the rug as the reigning theory of gravity around these celestial party animals.

Picky Eater Black Holes

10. Picky Eater Black Holes

Black holes: the universe's picky eaters who won't swallow just any celestial broccoli! Gentleman jesters of cosmic dining, these massive misfits defy popular belief and follow their own dietary guidelines: consuming a relatively small portion of their own mass, with the highest recorded black hole munching on a mere one solar mass every two days, or about 183 solar masses annually.

11. Stars Turned Noodle Soup

Next time you see a black hole, you might want to tell it to keep its hands to itself! As it turns out, these cosmic vacuum cleaners have a habit of turning stars into noodle soup: when a star drifts too close to a black hole, the intense gravity stretches it into a long, glowing spaghetti of hot gas, which then orbits the black hole, forming a disk that can outshine entire galaxies – all in just weeks or months!

12. Cosmic Sneezing Galaxies

Have you ever sneezed so hard that the rest of the universe said "Bless You" and then ghosted you for eternity? Well, some galaxies might just understand that feeling: Turns out, black holes aren't the only ones with event horizons – the point of no return where even light can't escape. The universe's expansion is so quick, it's causing galaxies beyond a certain distance to disappear from our view forever, as they too cross an event horizon, never to be seen again.
