Mikes10 Posted April 10, 2019 Share Posted April 10, 2019 Brian Greene hosts a discussion about black holes. This video was recorded before the published photograph. It is well worth a watch for those who are interested. https://www.youtube.com/watch?v=C-OyMPAq2PU Link to comment Share on other sites More sharing options...

As I understand it the pull of a black hole is so great that nothing can escape it. Everything is drawn in, even light. Soooooo.... How did any light (in whatever form) escape its pull to now be seen by our telescopes? It didn't. What they took a photo of is the gases being caught by the gravity and pulled into the black hole as they spiral towards the event horizon. It's not a photo of the hole, it's the stuff being sucked into it that makes it visible. Link to comment Share on other sites More sharing options...

FinBak Posted April 11, 2019 Share Posted April 11, 2019 It's a great photo and a massive leap in our understanding of Black Holes. Still there is that niggling thing....Where does all the matter end up? In the centre of a black hole, all matter is condensed to the point of 'Infinity'... Where is 'Infinity'?..And all the matter...?...It can't just 'Disappear'.! It will have to emerge 'Somewhere'. (Think about that..). Link to comment Share on other sites More sharing options...
