seems to me though i remember a theory that made the backside of a blackhole the the big bangand the beginning of somewhere else

In the Universe massive objects become spherical at a certain point of mass. (I'm sure they have a name for that point).

Black holes are spherical singularities of mass. The 'Light' event horizon is also spherical. No matter which way you look at a black hole you will see no light.

Matter coalesces at different rates on spherical masses. That is why planets and moons rotate. The unequal collisions of matter to the sphere causes it to spin. Black hole singularities spin too. Thus if it spins, it has a top and bottom.

Science has seen that black holes have gamma jets of energy being ejected from their poles. If you attempted to look at a black hole pole end, you wouldn't see anything, you would be fried.

Sagittarius A black hole gobbles up the matter from the Milky Way. The matter is spiral and kinda flat for a reason. The matter at its poles has been blown away by its enormous jets. All that remains is the matter caught in its gravitational influence at its equator.
There is a bar of density at the center of our galaxy.
That is currently the area of the singularity where the mass is highest.
That bar is spinning, where the bar ends and the spiral begins is a point of event horizon that is its 'matter' event horizon. The horizon at which matter is influenced by the singularity.

That is why it looks like a right angle to the spiral.
Its where matter is being pulled by gravity directly towards the singularity.
Light is not yet captured so we can still see it.

Thanks tom

I recall that.
It was based on the theory that black holes puncture the space-time fabric. I think it was dismissed because gravity is not unidirectional.

Mass pulls on space-time in all directions.

The two dimensional references of the ball on the trampoline are in accurate. The idea was that a ball massive enough could puncture the trampoline. Problem is space-time is around all points of mass. Just like if you threw a ball into the air, the air is around all points of the ball.

This is also why 'folding' space wouldn't work for faster than light travel. Can air be folded?

I also remember a theory that said there is a negative Universe that black holes dump into. Essentially they were 'white holes'. With the discovery of black hole gamma jets we now know that is not correct.

String Theory hypothesizes a multitude of different dimensions existing together. I don't think mass affects dimensional layers.
Yes mass can bend light by affecting the path of a photon because a photon is both a particle and a frequency. I have yet to see anything saying that mass affects sound.

Speed affects time but I am not sure how mass has anything to do with it.

Time is subject to relativity. If you are falling onto a black hole it may seem like time stopped. At a point at the event horizon it may appear that time stops because photons could be at a point of equilibrium and you may be moving faster than the photons but I would need to dedicate a bit more thought and research to the idea to understand it better.

I do understand that black holes do make sound. Sound is a frequency like light. Unlike light, sound has no mass. Black hole sound is at such a high frequency (gamma) we can't hear it. But is is still a frequency so in the same dimension as sound.

yes tom again if memory serves those all require acknowledgement or proof of more than 3 (4 if including time) dimensions
ie cube a line to get square
cube a square to get cube
then cube the cube

Okay, Time is the duration of change of state. That duration of change is relative to the state change being measured. So IMO, mass does not affect time.
That means that time at the surface of a black hole singularity is the same as time anyplace else.

Correct but only for physical dimensions.

What do you get when you cube time or sound or quantum state?
I'm sure someone is working on that but its beyond me?

yep except for the damned cat and the effect of observation

tho near light speed aging vs the stationary brother muddies it up a bit

so i think time is a bit more fluid

As far as black holes are concerned I don't think they affect dimensional states.
It would be like a ball poking a hole in time.
A ball can block sound because it blocks the frequency propagation but it doesn't change the dimension of sound, it reflects it or resonates it at a different frequency.
If the right frequency is used with the right materials of the ball, the ball could start to glow from sound because the molecules in the ball are excited to such a freqency of movement it causes radiation to be released as heat. Resulting in photon release. Since photons are both frequency and matter and matter has mass I guess sound can cross dimensional barriers. Now my feckin head hurts! LOL

the fact is that nobody knows what a black hole is, it was named that after Einstein did his thing... all we really know is there is something we can't see at the center of every galaxy...we know this 3 ways - the jets, when a star is eaten by a BH{1st pic} (which causes the jets), and the orbits of stars we can see(2nd pic)
