Re: Biggest ever seen black hole jets; blasting plasma well beyond their own galaxy

I thought that only hawking radiation could escape a black hole. Now a paper describing a vast jet of emitted plasma?? The article doesn't quite clarify this point. It mentions the jets shooting from below and above the black holes, but does this mean they're emerging from their interior or being created by the accretion of superheated material that forms in orbit around black holes? The article simple states this, w…

Its not coming out of the black hole itself, its more like the black hole has an accretion disk around it of material that is being sucked in. The dynamics of the huge forces and energies involved can cause jets to form, throwing high energy particles away from the black hole. The jets still represent a tiny fraction of the matter, most of which is still heading into the hole.

And crazy strong and twisted magnetic fields that will heat things up/create large forces on charged particles.

If the plasma jet is wildly larger than our entire galaxy, I wonder if some sort of exotic life could evolve inside the jet. Some sort of life that would be totally rare in the universe.

Sometimes I wonder if our whole universe is some kind of transient aberration, if you zoom out far enough

Not my field, but could the Big Bang have been a massive black hole that "spat" out jets of plasma that formed into new stars and galaxies? I call this the black hole big burp theory.

This seems incompatible with inflation

Some might say humans are exotic life that evolved.

This is very close to an idea known as "Black hole cosmology" -- basically the idea being that the visible universe is inside a black hole, leading to a sort of "nested multiverse".

A related theory, rather than being inside a black hole, is that the other side of a black hole is a "white hole". As matter collapses into a black hole, it is emitted from the white hole, creating another universe.

Here's an article from 2010 that expands on the idea, though this is definitely not the first time (or last time) it was discussed, it just happens to be an easily searchable article.
