Argh! Black holes! Me stupid! Help Erik understand physics, please?

Question

I know these:
- Objects that get really big with lots of gravity cannot support their framework and so the object just eats big bites out of itself until it and the surrounding material plus its color and its light are no longer visible.
- Stuff goes toward the imploded object which is smashed into a negative nothing. Yet it exists as a something because it effects other things. Or maybe these other things are just the excess fat of nothing?

What I want to understand is why are galactic jets shooting out of the rear-end of black holes? Are they shooting out? They look like it. And what are they made out of?

If black holes consume light, could it be that dark matter is matter that is being blocked to us-- the observer-- by a black hole(s) that is between us and the "dark matter"?

Could we be in a black hole, as we speak?

Answer 1

First forget about holes, and think stars!
A black hole got its name because you can only see one due to the lack of stars around it!
So now you have a star who's gravity is equal to the speed of light, it emits light, but it cannot escape from the surface.
Black hole have magnetic fields the same as stars, so the, "galactic jets", are materials converging at the poles.
And YES we are in a black hole, there is one in the centre of our galaxy, and it is powering the whole rotation!

Answer 2

The jets come from the accretion disks around black holes. The material is compressed and transformed from matter into energy at a pretty decent rate in this disk. The jets the shoot away are just the energy released at the event horizon of these black holes. They do not actually come from the inside.

Edit: Also dark matter is not matter that is hidden to us because black holes capture the light that the object emits. Dark matter is still not understood entirely but some theories are that it is gravity leaking into our universe from other ones.

Answer 3

Awk! Too many questions all at once.

The jets coming out of black holes are from the matter falling into the hole. Before it gets to the hole, it gets squeezed so much, and spun around so much, that it gets pushed out along the spin direction of the BH.

Look for "jet" in the second link.

Answer 4

It does not "consume" light.

It's a dying star that decreases in size but increases in rotational velocity, therefore making the escape velocity too high for even light. ie. huge gravitational force.

Things don't shoot out, they leak out, but that, and black holes themselves have yet to be proven
