These black hole thingummyjibs get up to a lot of strange behaviour. Even to the point of contradicting the idea of black holes. They were, not so long ago, supposed to devour any matter that came within their munching boundary. In fact, we used to get a lot of papers telling us about the eating habits of black holes. Not so much nowadays. Then we had a complete change of mind. The idea of an event horizon surrounding black holes – something they say that was actually visible in the telescopes of the day. The event horizon came about as black holes were throwing out jets – of energy. Hence, firstly we had black holes consuming anything that came near them – and active only when they were chomping on matter. Then we had black holes that were not just consuming matter but spewing it out at the same time – at the event horizon. Now, we have a number of new telescopes and arrays in service and black holes are becoming even more problematic. At https://dailygalaxy.com/2026/04/dancing-jets-black-hole-power-10000-suns/ … dancing jets unleash energy as powerful as ten thousand suns. The pin prick in space known as the Cygnus X-1 binary galaxy has become a focus of cosmological interest. It is said to be a binary system – comprising an orbiting black hole around a massive star. As it spirals towards the black hole powerful magnetic fields accelerate it into fast moving jets that appear to be dancing. The jets are beaming outwards. Not only are they fast moving jets but they are extremely powerful jets of energy – pumping out into the wider universe. The dancing comes about, we are told, by the intense stellar wind interacting with the black hole.
Why are they confident that a black hole is involved? These things are supposed to be so dense they are invisible – which is why the event horizon idea popped out. What else might be causing this to happen?
