Astronomers witness energetic switch on of black hole
- dathos 3y ago“Very Large Telescope”, I love this name. Any better ones out there?
- mecsred 3y agoThe checklist is accurate: https://xkcd.com/1294/ https://xkcd.com/1294/
- throwaway7868 3y agoIs the "final telescope" massive enough to be its own black hole?
- hinkley 3y agoThe OWL was cancelled? Can we propose the Obnoxiously Large Telescope to replace it?
- etra0 3y agoNow they're building the ELT –– Extremely Large Telescope. They're great with names haha.
- cyberax 3y agoDon't forget OWL: Overwhelmingly Large Telescope ( https://en.wikipedia.org/wiki/Overwhelmingly_Large_Telescope https://en.wikipedia.org/wiki/Overwhelmingly_Large_Telescope ).
- OldGuyInTheClub 3y agoOr, "Once Was Larger" "The ESO specialists expect resolutions from OWL that are up to 40 times higher than those of the Hubble Space Telescope. If the 100-meter mirror cannot be financed, a 60-meter variant is being planned. The name OWL would remain the same. Because then the project is jokingly called »Once was larger«." https://www.itespresso.de/2006/04/17/groesstes-observatorium-der-welt-pcpro/ https://www.itespresso.de/2006/04/17/groesstes-observatorium... --> Google Translate
- moffkalast 3y agoStill waiting for the Stupendously Gigantic Telescope.
- FredPret 3y agoThey should build one ten times the size of the next largest one, and call it the Quite Sizeable Telescope
- ProAm 3y agoThere is the "Very Large Array" too! the VLA. I love these naming standards. Way better than any startup or open source project name
- willis936 3y agoPotentially inspired by Very Large Scale Integration.
- ck2 3y agoGo read about the solar gravitational lens telescope proposal by physicist Slava Turyshev It is the most mind blowing thing that could actually be built someday by humans imho, well if we decide to stop blowing all our budget on killing other people https://google.com/search?q=solar+gravitational+lens https://google.com/search?q=solar+gravitational+lens It would be able to image exoplanets, 10 square kilometers for objects 100 light-years away.
- floxy 3y ago>solar gravitational lens telescope Here is a great video about it: https://www.youtube.com/watch?v=NQFqDKRAROI https://www.youtube.com/watch?v=NQFqDKRAROI ...and a paper: https://arxiv.org/abs/1802.08421 https://arxiv.org/abs/1802.08421
- nonameiguess 3y agoAstronomers are great at this. Three postulated categories of dark matter include: * WIMPs: weakly interacting massive particles * MACHOs: massive compact halo objects * RAMBOs: robust associations of massive baryonic objects There's also the HERO (hyper extremely red object), which isn't quite dark, but close.
- imchillyb 3y agoAstronomers and Astrophysicists are great at naming things. The rest of the scientific community...notsomuch. > https://www.youtube.com/shorts/uNnq2GrC01o https://www.youtube.com/shorts/uNnq2GrC01o
- denton-scratch 3y agoWhat does it mean for an AGN to "turn on"?
- treeman79 3y agoIt ate a star.
- ars 3y agoBut that would take infinite time (as we perceive the event) because of time dilation. You would not see it "turn on", you would see a slowly, very slowly, changing signal.
- drojas 3y agoI think this is good evidence in favor the plasmoid model from Eric Lerner as a replacement for black holes. Some key differences. * Instead of a black hole eating a star, a plasmoid is having an increased load. * Black holes are "gravitational" machines while plasmoid are "electromagnetic" machines. * With the plasmoid model there is no time dilation * With the plasmoid model, the load is any source of plasma, not necessarily a star https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=eric+lerner+plasmoid&btnG= https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=eric... https://www.google.com/books/edition/The_Big_Bang_Never_Happened/IwNVDMOgQRQC?hl=en&gbpv=0 https://www.google.com/books/edition/The_Big_Bang_Never_Happ...
- post-it 3y ago> With the plasmoid model there is no time dilation But there is time dilation, so the plasmoid model isn't very good at explaining observations.
- antonvs 3y agoIt might be good evidence for something else if it were correct. It’s not correct, though. As I mentioned in another comment, infinite time dilation (from the reference frame of an external observer) is only an issue exactly at the event horizon. But the events that lead to a supermassive black hole “switching on” are happening at the accretion disk, far enough away from the event horizon for time dilation to be an effect we’d have to measure carefully to detect. Also, the idea that you’d want a model that avoids time dilation here makes no sense. We know gravitational time dilation is a real effect because we’ve measured it, it matches the predictions of general relativity, and GPS would be very inaccurate if they didn’t correctly take the effect into account. To say that time dilation doesn’t occur near a black hole is completely inconsistent with well-verified facts. From this, we can conclude that Lerner’s conjecture is wrong. We can’t even call it a theory, because it doesn’t match the evidence.
- SomeRndName11 3y agoToday they witness energetic switch, tomorrow - energetic router.
- mrtksn 3y agoAnd still no reception in the kitchen.
- SomeRndName11 3y agokitchen must be beyond the event horizon.
- pixelpoet 3y agoThat's because of the CMB (cooking microwave in the background)
- civilitty 3y agoFollowed by a wireless gamma ray burst. Aimed right at us.

- gigatexal 3y agoMorbid but if I’m the future I’m terminally ill and we somehow find a cheat code to travel to a supermassive black hole in years instead of hundreds of millions of years I’d like to hop in a space suit and get launched into one Dave Bowman style.
