2 thoughts about Black Holes’ spacetime and jet-wobbles

Jonah Ohayv, Nov., 2018

Black holes have numerous stars just outside their event horizon (accretion disk = at the lips of their mouth) which can be fed upon when needed. The energy they receive from chewing up the stars and their surrounding gas, spins down the hole, where it is then redirected – partly to control the spin and size of the whole galaxy it’s the center of, and partly released again in spinning energized jets of gas and particles more or less perpendicularly shot out from usually both sides of the galaxy’s black hole. The ”mouth” changes its axis however in an adjustable wobble, so it can make adjustments in the surrounding galaxy. The jets are turned on and off as needed, like releasing extra steam, and adjust their spin, like fine-tuning the release. Their ejected material often forms big gas clouds at a distance from the galaxy, where new stars are born.

What I’ve been trying to figure out is: The arms of a spiral galaxy turn say clockwise – so from it’s backside, the arms look counter-clockwise. The galaxy is not one-dimensional flat, so looking from the side, it has an up and a down, with a Black hole entrance on each side, each of which draws material down towards the galaxy’s center. That either gives a terrific clash at the center, whereby almost all energy is released in all directions sideways, creating and controlling the galaxy’s revolving turning. And some of the ingoing energy will bounce back out the same mouth, helping to create the eventual jet from it. Or there’s no clash, but a cooperative two-way street, so some of the energy in the middle continues out the other mouth of the black hole.

The traditional science-fiction-movie fear that black holes gobble everything up forever is totally wrong. Also that nothing (that is, no visible light) escapes them: the jets are in the form of heated particles (infrared wave length and radio waves), so they’re energy on just other sections of the electromagnetic scale.

Likewise with binary stars (two which orbit each other, where sometimes one is invisible): the Black Hole in the second star may suck up energy from the first, and then release these in jets.

Now about space and time ”disappearing”. Time is measured by the movements of bodies (the Earth turning, a watch-hand moving, the degeneration process of an atom, biological growth, etc.). Space is extention. Our usual concept of space and time is an oversimplified reflection of the placement of our senses, our own biological processes and phases, that we walk and don’t fly or swim, etc. When we sleep or dream, where’s our time (even the metabolic rate changes)? When our conscious state changes, our time and space changes. So it’s not a question of spacetime ending, but of our conception’s assumed limits.

Our body-mind’s simplification into 3D space and past-present-future time ignores all the spaces and other dimensions around these concepts. If for example, you look from a high building at the activity on many streets below you, there’s an overall sense and simultaneity that you can’t view on the ground. In a Black Hole or galaxy, space and time change under the gravitional stress and movement, but they’re still there in (from our viewpoint) stretched and compressed forms.
