Black Hole Conundrum

15 Apr 2020

Stolen from the Tall Bloke - the headline that is. Nice video - see ... a video ofa supermassive black hole spewing a brilliant jet of particles (derived from ...). The blog author rightly asks - how does visible material escape from somewhere that nothing is supposed to escape from? He then quotes the Wiki - a black hole is a region of space time exhibiting gravitational attraction so strong that nothing - no particle or even electromagnetic radiation such as light, can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform space time to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. See the comments which are interesting.

The answer of course is that black holes can be messy eaters - the get out clause from the Wiki overview. It all happens at the event horizon - unless Tall Bloke can show us the electromagnetic light switch comes from within the so called black hole. Mainstream, when defending a  consensus theory, can be surprisingly fluid - even doing somersaults.
