suppose that everything in the universe is constantly engaging in a
kind of rotational motion around a single point in space.

1) Every point in the universe is at its exact center. all 4(pi)
steadians exactly point to the Big Bang.

Read the following carefully.

[Al]
2) Acceleration, linear and angular, is an absolutely measurable
observable in hermetic isolation - mechanical gyroscope, laser ring
gyroscope, Foucault pendulum, cantilever accelerometer, etc. Mount
three orthogonal accelerometers and look.

[Mark]
Now read the last sentence again. Keep it in mind, because he isn't
suggesting anything new.

[Blade]
If you take a basketball and put it on your fingers, and spin it, the
basketball is rotating. Now superimpose a basketball that is not
rotating. You can see the difference. In fact, on the 2D world of the
basketball's surface, the spinning of the basketball can be said to be
spinning about two fixed points. If you have a better choice of words,
then offer it.

[Blade]
That which
is close to the point in space is moving more slowly, and that which
is on the opposite side of space is not moving and that which is
closer to the other point is moving slower as well.
[snip crap, by Al]
If everything IS relative, shouldn't rotation be relative as well?

[Al]
Acceleration is absolute.

[Blade]
Yes, when the rest of the universe isn't accelerating. What if it is?
Shouldn't frame dragging make it so that if I wasn't accelerating and
the rest of the universe was, I'd feel like I was accelerating in the
opposite direction?

[Mark]
Irrelevant; even if you were being dragged along with it you could
measure it. "Three orthogonal accelerometers" are an essential part of
an "inertial guidance platform" which is pre-WWII technology. The
latest incarnations are laser gyros precise to degrees that would curl
your hair.
If the universe as a whole were rotating it would have shown up as
an irreducible bias even in much more primitive platforms decades ago.
It simply ain't there, therefore the universe as a whole is not rotating.

Right, Marky,
Even our observable portion of the Universe can not be rotating
because if it were, it will imply a single center and that center
would be the holy grail of the astronomers... ahahaha... & ***
all that 4D and curved space. These are mental masturbations
or math mind games that have no empirical counter parts in
the real world.
------------- now let's turn the glove inside out --------------
Start with, say, our solar system. Then ratchet up its dimensions
to galaxy size and beyond. Now, show how, the larger the
radius of such a matter containing 3 D space volume gets, the
slower its rotation becomes. Show/calc/project/estimate what
this rotational peripheral speed/velocity will be when the radius
reaches the size of the observable universe... ahahahaha....
ahahaha... ahahahanson
