What? Huh?

There are a few things I don't understand. Nothing is supposed to escape the gravity of a black hole, not even light. How do they explain "cosmic jets erupting from a supermassive black hole" and "particle jets that emanate from the black hole".

This quote might be a more accurate description: "These jets arise as infalling matter approaches the black hole"

And the mass, 55 million stars worth. Where did that come from if a black hole is the result of the collapse of a single massive star? 55 million stars are the equivalent of 550 globular clusters at around 100,000 stars each. This thing must have been sucking up matter for a very long time.

When black holes were first theorized, it was said that their mass was equal to 50,000 tons- in a matchbox. I think it's much more than that now. It boggles the mind.

Time to buy a ‘current’ cosmology book.
