They’ve discovered new stuff about supermassive black holes. 
You know how small children are afraid of monsters under the bed, or boogeymen? I never was. Black holes freaked me out, though. I would imagine a big one wandering through our solar system and swallowing the Sun before it hit the Earth, and to this day I still have nightmares about it on odd occasions. 
What weird stuff scares you?
