Correct me if I'm wrong, but plainly stated we have:

1) missing matter
2) gravity gets weaker by distance (beyond the inverse square law,
naturally)

It seems slightly obvious that a third conjecture would be something
like:

3) missing distance

In other words, the distance from the center of the galaxy to the tip
of the spiral arm is far greater than what is measured.

We know there is a black hole at the center of the galaxy.

We also assume that black holes look like a big black hole, with all
sorts of light coming from around the edges.

But we don't see that in the center of the galaxy, do we? I know, I
know, there is alot of light covering it up, in the way, right?

Maybe our picture of black holes is wrong, and the surface area of the
event horizon is essentially equal to zero. Instead of a black hole
with light around it, like a nice big halo, maybe a black hole
including the event horizon really is a single point, and the light
coming from around the edges of a zero-dimensional point, obviously now
just looks like light.

That would mean... in addition to the black hole "hiding" mass in the
center of the galaxy, it is also "hiding" distance?

It seems like something worth at least worth refuting anyways.

In any case, it is a testable hypothesis. If we directly measure the
surface area of the event horizon, we should affirm General
Relativity's prediction, or affirm the zero prediction and explain the
spiral galaxies at the same time?

177. Needless to day, the scenarios outlined above do not exhaust all
the possibilities. They only indicate the kinds of outcomes that seem
to us mots likely. But wee can envision no plausible scenarios that
are any more palatable that the ones we've just described. It is
overwhelmingly probable that if the industrial-technological system
survives the next 40 to 100 years, it will by that time have developed
certain general characteristics: Individuals (at least those of the
"bourgeois" type, who are integrated into the system and make it run,
and who therefore have all the power) will be more dependent than ever
on large organizations; they will be more "socialized" that ever and
their physical and mental qualities to a significant extent (possibly
to a very great extent ) will be those that are engineered into them
rather than being the results of chance (or of God's will, or
whatever); and whatever may be left o

Looking up from near the edge of the foam on your beer is "easier" than
trying to look through all the bubbles.
