The standard model
Inhomogeneous cosmologies
The standard model of cosmology assumes a homogeneous and isotropic universe, and as a description of the bulk properties of the universe, it has served us well. But the real universe is distinctly non-homogeneous on all scales except possibly the largest, so it is important to study the behaviour of inhomogeneities. Inhomogeneous cosmology uses exact solutions of the Einstein field equations to explore the full non-linear evolution of inhomogeneous structures.

The Metric of the Cosmos. This is the ultimate application of Einstein�s field equations � determining the relation between matter and geometry in the real universe. The idea of reducing observed cosmological data to a metric was first explicitly discussed by Kristian & Sachs in 1966. Though a fair bit of theoretical development has been done, the methods have never been implemented, and therefore key questions such as choosing appropriate numerical methods, anaylysing uncertainties, and how to handle the intricacies of real observational data, etc, have not been addressed. A numerical reduction scheme is being developed and tested with fake data.

The large amounts of cosmological data generated by current and future redshift surveys will make this project practicable in the near future. This data will allow us to move beyond the assumption of homogeneity, and instead quantify the degree of homogeneity or lumpiness on a metric level. More importantly, as the data becomes increasingly accurate, the proper reduction and interpretation of the high redshift data will require knowledge of the cosmic geometry that is traveled through by the light rays we observe.

Our universe in reality has parts that are expanding and parts that are contracting.

In addition we find extremely large voids billions of year across that the big bang cannot explain.

Hello Isreal

Thanks mate, will do.

Hello Israel

Again, I’m sorry, been away

You write with a pen of knowledge.

You have made me read up on Gravity. Be back soon

Hello Charles

Thank you for the link

Hello All

Israel said

They are right. The essence is that now there is no precise border which
divides two different frame of reference:
1) System of Vacuum and
2) Gravitational frame of reference.
Now these two systems are considered as though they were common.
But they are completely different systems.
There, where there is a vacuum – there is no gravitation.
In the vacuum, one set of laws – the laws of the vacuum work
( not taking into account external influences).
Where there is gravitation, there is no vacuum.
In a gravitational reference system a complete set of other laws apply.
These laws are connected and take into account external influences.

Sorry I did not see your response, been busy in other forums.

How do you know that there is no gravity in a vacuum? Sounds like the chicken and the egg.

Ok, you speak of reference:

What is your main Point? What has this got to do with the price of eggs?

Hello All

Israel maybe right.

History repeats time and time again.

Hello All

Many scientists have in the past been fed information that the Big Bang theory is the standard model supported by some form of evidence.

Some people think that the BB occured in one single spot. As per the BB theory, this is not the case. It occured everywhere from a singularity at the same time.

Much more than this: If you intend to support the BBT than support it with evidence and not emotional thoughts.

Why do you suppot the BBT?????????????

I do not agree with it. But! this is what some people think.

Hello All

What is dark matter?

Dark matter is matter that we are unable to see?

Most matter in the universe is plasma in the form of ultra dense degenerate matter. This dark matter we cannot see it because its so small and too far away.

Hello Mark

I think you are right,,,,,,,,,,,can you expand your ideas.

[pluto]

Hello All

Read them, but keep an open mind.

Are you just starting to learn cosmology.

If you want to more reading or wish to discuss, just let me know

Hello Mark

If the universe is endless in both time and space.

The parts within the universe undergo a recycle process.

I would not think that the total universe would do so. That is, it will not cluster to one single point. Why? Because infinity does not allows to do so.

So looking at the parts we notice

Planets
Stars all types
Galaxies
Cluster of galaxies
Cluster of cluster of galaxies
and so on cluster together undergoing an observable recycling process.

Before I posted this post I was looking at deep field images of cluster of galaxies.

Amazing images.

Lets have a look at some deep field clusters

9 and 11 Gyrs

http://chandra.harvard.edu/press/05_releases/press_040805.html
6 to 8 Gyrs

11 Gyrs

http://chandra.harvard.edu/photo/2004/darkenergy/
6.7 Gyrs

11 Gyrs

http://chandra.harvard.edu/photo/2002/1127/

Quote:
The X-ray image of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light years from Earth, shows an enormous X-ray jet that extends at least a million light years from the quasar. The jet is likely due to the collision of a beam of high-energy electrons with microwave photons.

Reading Chandra you would think that the Big Bang is reality.

13.2 Grs

Quote:
The HUDF field contains an estimated 10,000 galaxies. In ground-based images, the patch of sky in which the galaxies reside (just one-tenth the diameter of the full Moon) is largely empty. Located in the constellation Fornax, the region is below the constellation Orion.

Quote:
The NICMOS sees even farther than the ACS. The NICMOS reveals the farthest galaxies ever seen, because the expanding universe has stretched their light into the near-infrared portion of the spectrum. “The NICMOS provides important additional scientific content to cosmological studies in the HUDF,” says Rodger Thompson of the University of Arizona and the NICMOS Principal Investigator. The ACS uncovered galaxies that existed 800 million years after the big bang (at a redshift of 7). But the NICMOS may have spotted galaxies that lived just 400 million years after the birth of the cosmos (at a redshift of 12). Thompson must confirm the NICMOS discovery with follow-up research.

Now for a galaxy to form in just 400 million years is quite an ask. For a cluster of galaxies is going to far with the question.

Compare this with the evolution of our solar system and its life expectency of about 10 to 12 Gyrs.

Something is wrong. Are we blind not to question?

Soon we will look into deep field over 14 Gyrs. What than?

Hello Mark

Please excuse me.

What are you trying to say?

[pluto]

Hello Aaron

I agree with you.

The clusters formed within the known universe have a similarity from the basic atomic structure.

The seed produces the tree and the tree produces the seed.

The cyclic universe, endless and timeless in space and matter.

Hello All

Olbers Paradox.

http://aeolist.wordpress.com/2007/03/21/the-modern-day-olbers-paradox/

Some say its not a paradox

It becomes a paradox because man is in conflict over the paradox.

Based on

Is the universe endless or finite.
