The fact the gov wants to shut down our only xray telescope for "budget reasons" genuinely pisses me off
-
NOBODY expects the Spanish Inquisition... or dormant black holes relatively close to the solar system.
-
One model, a ways back, suggested about 10 million unseen blackholes should be wandering around the Milkyway...
-
A black hole is close enough to actually send a long term mission to. Exciting stuff for people in guessing about 5 to 8k years.
-
Very interesting work based on X-Ray detections! Good thing we have a dedicated X-Ray satellite, Chandra..... Uh, what? They want to shut it down to save money? Really? Really. Apparently someone decided the place to save a few bucks...was the NASA budget.
-
This shouldn't be too surprising. The gravity wave interferometers have been finding black holes of this mass since they started. I believe the first black hole merger they detected were black holes around this size.
-
Just want to say thank you Anton for your daily uploads. Can't imagine the time and dedication it takes research every episode.
-
"In the constellation of Cygnus There lurks a mysterious, invisible force The black hole of Cygnus X-1 Six stars of the Northern Cross In mourning for their sister's loss In a final flash of glory Nevermore to grace the night" Neil Peart 1977
-
Imagine traveling to another star and accidentally flying into a dormant black hole because you had no idea it was there until it was too late since the gravity is too strong already
-
I’m putting $5 on Planet 9 being a mini black hole…
-
I imagine there are millions of small undetected black holes in the Milky Way. So any future space travel needs to have a way to detect gravity ways or something.
-
I misread the title as 'Doormat Black Hole Found' - I was like, wow, Anton has real contempt for supermassive stellar objects
-
2:24 woa woa woa, I had no idea a star could even become a black hole without going supernova! Could you make a video on this specific topic explaining it in further detail?
-
I find myself amused at miss-hearing certain lines like "Ultra violent observations"
-
Bought one of Kip Thorne's books on black holes in the 90's. Written so a non science person as myself (went to business school) could understand. Not sure if would have had the smarts for it, but if could go back in time, I'd probably go for it and change my major. These interests have been with me since childhood, writing space stories even then. Thank you (wonderful human) for such a great channel.
-
Press f to pay respects to Chandra, likely going to be decomissioned. There's a petition out to keep it on budget for upkeep and repairs, but it's not looking likely to make a difference.
-
A sneaky black hole, I also had a X-Ray and I ended up looking like a spooky skeleton!
-
And… Oh wait… Oh, man, I think I’m hearing the faint sound of people having an existential crisis
-
Anton, no one makes me more excited about astronomy like you do!
-
Thanks for covering this news Anton.
