- excalibur 7y agoNear the boundary anyway. The headline is poorly worded, but the argument is that some of these objects aren't black holes at all. I don't think the "event horizon" term really applies to GEODEs. I also don't think they have too clear an understanding of what this crust would consist of, or if they do the article fails to mention it.
- ars 7y agoThese objects would no longer be black holes, and would not have event horizons. LIGO and other detects are not able to tell the difference. Black holes are assumed based on the mass, event horizons have never been detected, just [mathematically] assumed.
- bwood 7y agoDoes this not count as detection of an event horizon? Or is it just considered strong circumstantial evidence? https://eventhorizontelescope.org/ https://eventhorizontelescope.org/
- ars 7y agoNo, that is not evidence of an event horizon, it's not circumstantial evidence either because it pre-supposes the existence of one. Despite the name, no event horizon was directly photographed. Partly because event horizon's are not actually visible LOL. The photo taken can not distinguish between a true black hole, and a super massive object of the same mass. We just assume that if you have that much mass there is no force that is capable of preventing it from becoming a black hole. But, that's not proof that such a force does not exist.
