Observational Evidence...
There are two kinds of expansion, the first kind (1) Accelerates and then slows down, and the second kind (2) which starts slowly and then accelerates.

Well, to follow your obscure parlance...There are also:

1. Starts slowly and then slows down
2. Accelerates slowly and then accelerates quickly
3. Maintains a steady rate of expansion
4. Maintains a steady rate of expansion and then slows down
5. Maintains a steady rate of expansion and then stops
6. Accelerates, slows down and then accelerates again
7. Starts quickly and then accelerates
8. etc.

So, it doesn't look like your initial premise holds up.

That must be how the slow-moving serial killer manages to catch the fleeing teenager in horror films...Edited by Panda, : No reason given.

I did not claim anything regarding regarding this: I did not say that air doesn't travel in to the nozzle.Here is what I wrote: So, back to what you wanted: your 'Observational Evidence'... No - there are many kinds of expansion (see above).Edited by Panda, : No reason given.

...and several other kinds of expansion (see my previous 2 posts). I can't understand why you are unable to see the other kinds of expansions I listed. Let's focus on one claim at a time. No - there are many kinds of expansion.

So - you weren't saying what you were really saying.Before I go down this new rabbit hole - are you retracting your claim that: You are now abandoning your original claim and are now saying: Correct?Please confirm that you no longer believe that "There are two kinds of expansion, the first kind (1) Accelerates and then slows down, and the second kind (2) which starts slowly and then accelerates." Well, it would help if you didn't keep changing your claims.Edited by Panda, : No reason given.

What slows down? Their speed.
How did they get that speed? From accelerating.
So, your own definition says that outward expansions all accelerate, slow down and then stop. ...and also outward expansions.
If you don't believe me, ask Peter Lamont.

An "initial kick"?
What do you think the "initial kick" does?
It accelerates the outward expansion.Your claim that outward expansions do not accelerate is contradicted by your own statement.Edited by Panda, : No reason given.

Yes, outward expansions accelerate.
I agree.But you don't seem to agree: Edited by Panda, : No reason given.Edited by Panda, : No reason given.Edited by Panda, : No reason given.

Yes - it is an accelerating outward expansion.
No need to repeat it.
I agree - it is an accelerating outward expansion. Even if the outward expansion accelerates for just 1 second, it is still an accelerating outward expansion.
This clearly conflicts with your other claim that "Any 'accerlerating expansion' is Inward." I've told you what I think: I think your statements are contradictory. "explosions (Big-Bang) start by accelerating." contradicts "The only kind of expansion that accelerates is Inward."I don't know how to make it any clearer.Edited by Panda, : No reason given.

Yes - it is an accelerating outward expansion.It is an outward expansion, yes?
And it is accelerating, yes?
Therefore....it is an....accelerating outward expansion, yes?
The outward expansion is accelerating, yes? But if you listen to what Peter Lamont and I have been saying: "Outward Expansions ... they start by accelerating." you will see that both inward AND outward expansions accelerate.Is that clear enough for you?

So - finally you agree that both inward AND outward expansions accelerate.
Great. Expansion (outward expansion) goes through the following stages:
1) Zero velocity
2) Acceleration
3) Deceleration
4) Zero velocityThen contraction (inward expansion) goes through the following stages:
1) Zero velocity
2) Acceleration
3) Deceleration
4) Zero velocityOk - let's look at your new claim: What do you mean by 'continues'?
Are you saying that inward expansions never slow down and stop?Edited by Panda, : No reason given.

One issue at a time.
I'll come back to that. It is in between 'terminal velocity' and 'stop'.
You can't go from 'moving' to 'stop' without decelerating. If you didn't slow down and stop then you would shoot past the centre of the black hole and head off back out in to space.So, unless you have an alternative way to reduce the speed from the terminal velocity to rest, then contractions (inward expansion) decelerate.

Expansion/Contraction is not affected by spin.
If you inflate a balloon while it is spinning, it still expands (outward expansion) at the same speed as when it is not spinning.
If you deflate a balloon while it is spinning, is still contracts (inward expansion) at the same speed as when it is not spinning.Expansion is measured by the change in distance between the expansion 'surface' and the centre of the expansion.
Even if an object at the centre of the expansion is rotating, that does not affect how far the surface of the expansion is from the centre.Let's look at your own words again: So....how does it stop without decelerating?
I am not putting words in to your mouth - this is what you said and I am simply trying to get you to understand what you have said.You say that the expansion stops.
How can it stop without decelerating?So - to try and put it as simply as possible:
How does something stop without slowing down? If you don't want people pointing out your mistakes, then perhaps posting them on a discussion forum is not the best idea?

This does seem to be the main point that Peter is unable to grasp in his "Where is the 'average density 'greatest?" question.
