Who dealt this mess...
You have completely misunderstood me. I maintain that in the Cosmic Background Radiation (CBR) the rate of expansion is slow and that increases further in.
The CBR is distributed throughout space. It is not located some distance away from any point, and accordingly the idea that some location is 'further in' the CBR is completely without meaning.
Something I've noticed = Old people don't like this theory. Young people are 'glad I came'.
How old are you?

Yes, it exists in the back-ground, rather than nearby.
No, Peter you are wrong. You have a gross misconception regarding the CBR. We detect the CBR by detecting the radiation that reaches detectors on earth or detectors in space near earth. The radiation itself fills all of space and is highly isotropic (uniform through out space). Earth and the solar system are already as far into the CBR as it is possible to get.
he Star Nurseries found there
You mean the star nurseries such as the ones in the Orion Nebula, a mere 1300 light years away from us? Where 1300ly is a tiny fraction of the radius of the observable universe? Is that what you mean by 'further in' to the CBR. Please think this through.
Go back to my 'Observational Evidence,' that I use to support my Theory.
About that evidence...
How old am I? How old is the Universe - trillions of years.
Probably the most accurate thing you've said yet.

Interesting question. Now, if there is such a thing as 'average density,' then the highest 'average density' will always be at the barycenter, Virgo Cluster included.
Here is an example in contradiction.
When Jupiter and Saturn are on the same side of the solar system, the center of mass of the solar system is outside of the sun, and clearly not in the most dense part of the solar system which would be in the sun's core.
Below is a simulation of the sun's motion with respect to the solar system barycenter

No Nukes, if Jupiter and Saturn are on one side of the sun, that pulls the barycenter out of the sun? I find that hard to believe, but if it does, then at the barycenter is the densest 'average density' because we are including the masses of Jupiter and Saturn in these calculations.
You aren't making any sense.
The barycenter can be completely outside of the sun's photosphere but not beyond the sun's corona. The corona region is very sparse, and is nowhere near as dense as the core of the sun. Surely you can understand that.
It turns out that the center of mass of the solar system varies with the location of the planets. The center of mass is at the most dense part of the core of the sun only very rarely.

Do you believe the Universe is a mere 13 billion years old, or are you agreeing with me that the Universe is trillions of years old?
I am not aware of any evidence suggesting that the universe is trillions of years old. But given your claim that old people don't put much stock in 'your physics', I think it is only natural that I would be interested in how old you are.
Do you believe the Universe is run by Gravity or Anti-Gravity?
I am not aware of any evidence that there is any such thing as anti-gravity. What does 'run by gravity' mean?
Are you aware that any 'accelerating expansion' is Inward (as opposed to Outward) ?
No. I find your suggestion ridiculous. What direction is 'inward'?

There's no such thing as density at any point. Your claims of such a thing are meaningless.
Yes, there is such a thing as density at a point.
We can talk about density at a point by assigning it the value of the mass divided by volume of a small differential volume enclosing that point. The concept is analogous to the concept of instantaneous velocity at time = t.
So you can't just calculate the density at that point by dividing the total mass by zero volume. In this case L'Hopital's rule doesn't help.
L'Hospitals rule would work if you had a continuous, differential expression for the mass at points in space.
There is no difficulty in assigning a density to the barycenter of the solar system. But the value varies with time.

You'll have to convince me that L'Hopital's rule is applicable
I'll take a shot at it.
The short answer is that L'Hopital's rule is the mathematical basis for evaluating a derivative. So what you are asking me to do is to find an application for a derivative to evaluate density at a point.
Let's take an example where the mass distribution of an object that is spherically symmetrical about the origin, but where the mass per unit volume increases as some continuous function of r, where r is from to the objects center.
We can imagine that when we measure the mass of spherical shells at a distance r1, we see that the mass of a sufficiently thin shell is approximately deltaM = C(r)* 4*pi* r1^2 *delta r for small values of delta, and where C is a function of r alone and reflects the distribution of a matter per unit volume as a function of r.
Then the density at a given point would be the limit of Delta M over delta V for the thin shell spherical shell centerd at the origin, with C being [i]constant for the entire spherical shell[i] of radius r and thickness delta r. We see that density at point r is simply limit deltaM/deltaV as r->0. in this case both delta M, given by the expression above, and delta V (which is simply) 4*pi*r^2*dr, are both zero for delta r=0 which allowing us to apply L'Hopital's rule.
Of course that application of the rule results in the density at a points r away from the center of the object being simply C(r). We would conventionally use rho instead of C to describe this function, but I thought that would make the explanation too circular.
But in any event, you are probably well aware that the density of a planet like the earth is roughly a function of distance from the core, and that if we had physical access we could evaluate that density by weighing small fixed volumes at various depths. Doing so approximates the derivative dM/dV which addresses the issue that it is normal and conventional to talk about density at a point.

and any accelerating expansion is Inward as I clearly show in ,my Observational Evidence,
Actually, you did not show any such thing.
You simply provided a couple of likely to be non-analogous examples, and then generalized to the universe, something that isn't all that much like the a bird flapping its wings, a snowball, or air approaching a vacuum nozzle. Do we need special or general relativity (GR) to describe those things? No, so we should expect the physics of expansion modeled using GR to be different, probably in significant ways.
When you keep asserting that you have clearly established something using Observation evidence, when you actually mean look at this similar things you've likely misinterpreted, then you look like a dime a dozen physics crank.
To say the enire Universe is expamding, because the OU is expanding is poor science, especiall;y when in 1998 they found that the expansion was accelerating
First, you are making the same mistake you are accusing everyone else of making. Is the entire universe actually undergoing accelerated expansion, or is the observed expansion actually of a completely local effect?
Secondly, show me the math. Or is that part to be left to the scientists?

Surely you can at least see the irony in your posting a message asking me to be more "coherant".
But more to the point, asking me to be more clear in response to the collection of belly-farts that make up your position in this thread approaches Ozymandias level hubris. "We're going in?" Please.

Re: Irony meter hits the peg...
This theory breaks no Laws. You call these Laws, 'Belly-Farts', that's your opinion, of course. It tells me more about you, No Nukes,
First, your nonsense does not constitute a theory. Secondly, I haven't called the laws of physics belly-farts. That term refers to your extrapolation of those laws into dissimilar situations. Thirdly, I could not care less about your opinion of me.
Density of a location in empty space is the highest average density of a system? That's an indefensible belly fart.
Ozymandias level hubris? That's supposed to be clear? I don't think so!
It's clear. I have provided you with the poet's name. I think the average person could have found the poem by now.

Re: Irony meter hits the peg...
Okay, No Nukes, you continue to misquote me - well that's your business,
Well, let's see who is actually telling the truth:
Here is my paraphrase which you suggest is a misquote:
NoNukes writes:
Density of a location in empty space is the highest average density of a system? That's an indefensible belly fart.
And here is what your actual burp (i.e. posted nonsense) states verbatim.
Peter Lamont writes:
Taq, the barycenter of a binary star system, even though there may be nothing there - has still the highest 'average density.'
Of course after posting a few more bits of nonsense on highest average density that isn't between your ears, you indicated that you did not want to discuss the subject anymore because no one else could follow you.
Ozymandias, by Percy Bysshe Shelley
I met a traveller from an antique land
Who said: "Two vast and trunkless legs of stone
Stand in the desert. Near them on the sand,
Half sunk, a shattered visage lies, whose frown
And wrinkled lip and sneer of cold command
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed.
And on the pedestal these words appear:
`My name is Ozymandias, King of Kings:
Look on my works, ye mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away".

Just becausen you don't understand 'average density,' doesn't make me wrong.
I do understand average density, and unlike you, I know that the average density of an empty area of space is zero.
But that's all beside the point, which is that your accusation that I misquoted you was way off base.

I know what extrapolate means. It means to take a situation here on Earth, and apply it to Space.
That would be one type of extrapolation, but it is not the one you are being accused of doing.
What you are doing is taking a thought experiment regarding motion of air molecules in a vortex, and insisting that space time behaves similarly. Nobody is going to accept that your analogy is correct without seeing the math, and you don't have any math.
