As matter spirals into a black hole, it speeds up more and more until it approaches the speed of light, most researchers agree. The matter -- stars, gas, dust -- becomes superheated, and is called plasma.

But not everything heading toward a black hole goes in. Some energy is squirted out in two opposing jets, along the axis of the black hole's rotation.

Astronomers have detected these ejection jets in radio waves and X-rays. They suspect that the infalling matter and the outflowing energy are related, all having to do with the violent interactions that occur right where matter reaches the point of no return, a sphere of influence known as a black hole's event horizon.

Strong magnetic fields play into this interaction. The research the scientists combined data about plasma swirling into a black hole with knowledge about how gravity and magnetic fields would affect it.

"In this case, jets of pure electromagnetic energy are ejected by the magnetic field along the north and south poles, above the black hole," said David Meier, an astrophysicist at NASA's Jet Propulsion Laboratory who worked on the study. "The jets contain energy equivalent to the power of the Sun, multiplied ten billion times and then increased another one billion times."

I watched something about them a few years ago. If you are wondering what would happen if one was sucked into a black hole, it is theorized that the "Spaghetti effect" would occur, and the person sucked in would be stretched out to their greatest capacity and then explode from all of the pressure.
That might be fun.

A black hole is a huge amount of mass compacted into a very small size, and technically it has no size because it is virtually nothing, only theoretical dark matter. It has a huge gravitational pull and pulls in everything around it even light cannot escape. It also emits X-rays from its rotation and pull. Which is one of the very few ways now that we can "detect" them.

The same effects that hold true for brown, red, and white holes.

the gravity is so large that it sucks everything in. even light cannot pass through the black hole

The mass is so dense that it results in a crushing gravitational field from which even light cannot escape.
