Reply to comment by smurficus103 in For the first time, astronomers have observed how certain supermassive black holes launch jets (outflows of ionised matter) of high-energy particles into space by The_R3venant
That’s impossible. The event horizon is the point at which space falls towards the singularity faster than light speed. For anything to come back out, it would have to move faster than light. For any matter as we know it to move faster than light, it would require infinite energy.

You're right, i tend to think in more classical physics and not GR, but it's still fun to contemplate... ya know, could some magnetic generation inside of a black hole rival the force of gravity? Particularly if you don't think of these things as singularities and instead objects with a bunch of stuff happening inside that collectively are enough local energy density to always bend light into orbits
Dont get too excited by this article, they say it's probably a coincidence at the end of the article https://www.forbes.com/sites/startswithabang/2020/06/25/shocking-new-observation-merging-black-holes-really-can-emit-light/?sh=35cd33a417bf
