I just had a thought. Maybe a new thought...

Suppose matter and antimatter are not opposites,
but created by fields at right angles to each other.

They might not attract or repel each other, nor
would they annihilate, but twist together like the
electric and magnetic and become photons... That
would look like annihilation, but totally different.

If the the field we already assume we know about
is Higgs', then the field responsibe for anti-matter
must surely now be Ken's. You're welcome...
 
Lets go on about holes for a sec:
I promised you an explanation about
the donut. Now seems opportune.

Scenario, junk falling to a singularity:
Sorry, there ain't time enough in this
universe for that to have occurred yet.
And thanks to dilation, it never will.

Scenario, junk falling to a thin shell.
Newton sais there is no gravity inside
a hollow shell, but still looks the same
outside. Time might restart inside, and
anything trapped inside by a growing
event horizon can migrate outward to
get re-stuck in the new shell.

But junk tends to spiral inward and not
evenly from every direction, certainly
not against the wind of the jets. Thus
the shell builds in the form of a ring.
Which due to internal time becomes a
donut.

Or could be a distorted shell without a
donut hole. But the jets give evidence...
I think a near miss with a donut might
easily make for jets, with or without the
help of magnetism.

Donut also allows conservation of angular
momentum required for magnetism.

Might be close to infinitely dense, but 2
dimensions, its not an absurd singularity.
The inside is probably full of Hawking
radiation migrating to some other part
of the shell, only to get stuck again...

Which would just as likely escape nowhere but convert back to
mass in constant equilibrium. At the extreme, mass and energy,
probably all the same thing.

If we assume equilibrium might occur at 50% energy, 50% mass.
We are still talking 50% the mass of TWO supermassive holes...
So, this presumed release of energy thats going to easily wipe out
an entire _______ is not going anywhere...

There is a possibility that the gravities of matter and anti-matter
repel, and the proposed merger could never occur. But since we
never see reversed lensing, both assumed types of galaxy would
appear to exert the same curve of spacetime upon passing energy.

I do not agree.. testing (at CERN) provides enough information to conclude that pro- and antimatter combine in energy. Not in an equilibrium of matter and energy. The two massive black holes thus will combine in one epic energy flash with some pro- or antimatter...

It would definitely be a nice firework in the night- or even day sky, but nasty when the energy hits.

Enjoy your donuts... 😉

But, they may already have and the energy released just has not reached us yet.


Back to how big the universe is and our position within it.

When the big bang occured, mass adn energy acceleratedin every direction. From the standpoint of a three dimensional universe, there should be very little left at the "center" of this event.

However, we are attempting measure the "edges" of the universe and from the pictorials I've seen have positioned our galaxy neer the center.

If I were to go 1/2 the way toowards what we define as the "edge" of the universe (direction won't matter) and take the same measurements to find the "edges of the universe, Would I find that I am still at the center of the universe and the distance to the "edges are the same in all directions?

Massless energy warps space and time just like mass. See Follow-up #1

Therefore a hole+antihole (or donut+antidonut) merger isn't releasing
anything, even if the combination annihilates entirely to energy.

You forget that matter, antimatter, and energy are all exchangeable
currencies under adequately extreme conditions, and none can escape
that gravity well. This is the jelly in the donut.

It should be noted that even if the mass is not uniformly distributed, it will still have a center of mass that would behave (from the outside) as if all of the mass is at that central point 😉

I never mentioned warping time and/or space due to matter/antimatter combination.

The combination of matter and anti-matter (no matter the concentration) will result in an immense energy surge. Because of the transformation of anti-mass and mass into energy, there will be no more gravitational fields (which are related to mass, not to energy) to contain the energy to the location. The energy therefore will explode in all dimensional directions.
 
I agree, there is a lot of stuff in an empty glass.

Anyhow I think, the Doppler shift is misinterpreted. The analogy is similar to that of an approaching car, the sound frequency increases while the car is coming at you, then decreases once it passes you.

What is not immediately apparent is whether or not the passing car was accelerating, or decelerating, both of which will produce a Doppler shift.

A theoretical controlled demonstration could have a car decelerating while approaching you, then accelerating immediate after it passes you.
If all you had was a frequency to guess where the car was going you would say it is sitting still in front of you.

While there may be some useful observations in Hubble's career, this does not provide evidence to support a Big Bang theory.

Gravity is the warping of spacetime wherever something exists.
It won't go away just because you convert mass to photons.

On doppler shift: a factor you don't hear about is differences in gravitational density, which influence light speed too. More gravitational density means a reduction in light speed seen from a distant observer. For the local observer this change in light speed might translate into some redshift, but not as a speed change due to Einstein's Theory of relativity.

Yes, that might be confusing.
