Andromeda is going to collide with us. Save the Milky Way!

The current model, based on gravity alone holding things together,
balanced against the effective centripetal and centrifugal forces as
in any stable orbit, works just fine.

Read it carefully and if you have a problem, be specific.

That is a bunch of somebody trying to sound important and sophisticated. But it makes no sense. Scientists already know gravity is not what is holding the galaxy together, so they insert the word "dark matter" into the equation. But that makes no sense either, since nothing at all is known about dark matter or how it holds the galaxy together.

1st - same to you buddy

2nd - you should post so others can easily read. I for one skip over
many posts because it's so much trouble scrolling right and left on
every line.

3rd - things emitting light are likely to be the exception rather than
the rule. They have to be quite hot. So, likely a lot of stuff out
there that can't be seen. But dark matter isn't even necessary to
account for a stable galaxy rotating at the correct speed with only
gravity holding it together.

4rd - are you proposing something additional to gravity, as yet
undescovered and unenvisioned by science ? If so, why don't you let us
in on it ?!

Well it obviously does. If not gravity, then what ?

No one knows. But you are never going to find the answer if
you keep inserting explanations that make no sense.

Isn't there two other forces ... Centripetal Force and
Centrifugal Force, or some such?? One acts to try to pull an
orbiting object towards the centre whilst the other acts to
force the object away from the centre. When the two are equal
(or is it "close to equal") the object orbits the centre.

The question remains what is holding the galaxy to its center as
it wheels about.

Didn't I just suggest Centripetal/Centrifugal Force would do
that??

If not, that is what I was trying to do!

Centrifugal force is what spreads the galaxy apart--it is not what
holds it to its center.

... and *what does Centripetal Force do* , Mark??

Centrifugal force pushes rotated objects out--does not hold them in.

.... and *your* answer to *the question I actually asked of you* (the
question I've highlighted above) is ...??

I don't think dark matter or gravity are holding our galaxies together.

I think what is the holding the galaxies together is the very same thing that

draws hydrogen atoms together to form a baby solar system; the very same thing

that coordinates all the necessary conditions for life on planet Earth; the

very same thing that keeps the Saturn V rocket from falling over during launch.

The very same thing that turns popcorn inside out. The Supernatural. You can

make your own speculation as to where that comes from. I know not to go

anywhere near there with scientifically minded people.

I just told you what it does. It pushes an object rotating around some center
outward.

Centrifugal force is an imaginary force...

https://en.wikipedia.org/wiki/Centrifugal_force

"... centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) directed away from the axis of rotation that *appears* to act on all objects when viewed in a rotating frame of reference..."

No, you didn't, you told me what *Centrifugal force* does. I asked you

I don't care how it's spelled. People still don't know what they are talking about.

I don't think dark matter or gravity are holding our galaxies together.

Gravity between all matter is indeed what's holding the galaxy
together against rotational forces, as in any stable orbit.

Not even the scientists think that anymore.
