Electromagnetic fields are part and parcell of the workings of the universe small and large. They are prime in explaining supernova and galaxy evolution.

If 95 % of all matter is unknown then how can the standard model be the standard?

This link is intersting reading with respect to the point of the 95% unknown matter. The pdf is about 54 pages.

What kind of science is cosmology?

Authors: Hubert F. Goenner
(Submitted on 22 Oct 2009)

Abstract: In recent years, by theory and observation cosmology has advanced substantially. Parameters of the concordance or $Lambda$CDM cosmological model are given with unprecedented precision (“precision cosmology”). On the other side, 95% of the matter content of the universe are of an unknown nature. This awkward situation motivates the present attempt to find cosmology’s place among the (exact) natural sciences. Due to its epistemic and methodical particularities, e.g., as a mathematized historical science, cosmology occupies a very special place. After going through some of the highlights of cosmological modeling, the conclusion is reached that knowledge provided by cosmological modeling cannot be as explicative and secure as knowledge gained by laboratory physics.

You have read my words out of context.

I read 3 or 4 papers per day.

I do not know what you have read.

Once reading any papers and if you wish to discuss I’m all ears.

Knowing how matter contracts and expands is a cyclic process that is ongoing and does not apply to the total form of the universe.

We see this in star formation
We see this in cluster of stars
We see this in galaxy evolution
We see this in cluster of clusters of galaxies with an AGN that forms a megagiant jet ejecting matter and reforming its own galaxy form and galaxies afar.

Centaurus A Jet:
Energetic Jet Meets Resistance In Nearby Galaxy

Jets such as the one in Centaurus A Jet are widespread phenomena in the cosmos, and represent one of the primary means for extracting energy from the vicinity of a black hole. Some jets extend over distances of a million light years. They represent a major energy source for the galaxy and are thought to affect the evolution of the host galaxy and its surroundings. The Centaurus A Jet image will help scientists to understand the effects of jets on their environment.

G’day Phills dad

Phill without being disrespectful, have you read some of the papers from.

http://www.cosmology.info/newsletter

The BBT is very theoretical.

To undertand how matter contracts and expands you may need to read up on jet formation small and large and giant and megagiant. These jets can influence the form near and far. From star surround to clusters of stars to AGN from a few hundred light light years to thousands of light years to millions of light years affecting galaxies far far away.

What do you mean by relic radiation?

Also what do you think of the BBT and the expansion of the universe?

Please do not think I’m pushing the question aside.

If you had one question about cosmology.

What would it be?

G’day Phills dad

I feel that I’m talking to myself. My son is Phill and thus I’m called Phill’s dad.

Why does the universe exist, because it is infinite? The Laws of physics can be applied to it.

Why do we have different phases of matter? That is a different type of “WHY”.

My favorite word through school was “WHY”: I wanted to know why things work.

Such as

When someone says the Star collapsed into the core. I want to know the “WHY” the WHEN” the “HOW” and the “WHAT” and so on.

The Universe does not need a reason to exist.

It exists without limitations.

It exists because matter cannot be created or distroyed.

It exists because matter recycles from one form to the next and this is where the fun starts in understanding the formation and evolution of form.

This is not coming out of my head, its coming from the many many papers explaining the events by using science and observations rather then ad hoc theories to make a model work.

TOPICAL REVIEW: The gravitational-wave signature of core-collapse supernovae
Mar-09
http://adsabs.harvard.edu/abs/2009CQGra..26f3001O
http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=2009CQGra..26f3001O&link_type=PREPRINT&db_key=AST

We review the ensemble of anticipated gravitational-wave (GW) emission processes in stellar core collapse and postbounce core-collapse supernova evolution. We discuss recent progress in the modeling of these processes and summarize most recent GW signal estimates. In addition, we present new results on the GW emission from postbounce convective overturn and protoneutron star g-mode pulsations based on axisymmetric radiation-hydrodynamic calculations. Galactic core-collapse supernovae are very rare events, but within 3 5 Mpc from Earth, the rate jumps to 1 in ~2 years. Using the set of currently available theoretical gravitational waveforms, we compute upper-limit optimal signal-to-noise ratios based on current and advanced LIGO/GEO600/VIRGO noise curves for the recent SN 2008bk which exploded at ~3.9 Mpc. While initial LIGOs cannot detect GWs emitted by core-collapse events at such a distance, we find that advanced LIGO-class detectors could put significant upper limits on the GW emission strength for such events. We study the potential occurrence of the various GW emission processes in particular supernova explosion scenarios and argue that the GW signatures of neutrino-driven, magneto-rotational, and acoustically-driven core-collapse SNe may be mutually exclusive. We suggest that even initial LIGOs could distinguish these explosion mechanisms based on the detection (or non-detection) of GWs from a galactic core-collapse supernova.

Cosmology and Astrophysics without Dark Energy and Dark Matter

Authors: Shlomo Barak, Elia M Leibowitz
(Submitted on 14 Sep 2009)

Abstract: We show that there is no need for the hypothetical Dark Energy (DE) and Dark Matter (DM) to explain phenomena attributed to them. In contrast to the consensus of the last decade, we show that the time derivative of the cosmological scale factor, is a constant. We derive H(z), the Hubble parameter, as a function of the redshift, z. Based on H(z), we derive a curve of the Distance Modulus versus log(z). This curve fits data from supernovae observations, without any free parameters. This fit is as good as that obtained by current cosmology, which needs the free parameters Omega_M and Omega_Lambda. We obtain these results by using the hitherto un-noticed fact that the global gravitational energy density in our Hubble Sphere (HS) is equal to the Cosmological Microwave Background (CMB) energy density. We derive the dynamic and kinematic relations that govern the motions of celestial bodies in and around galaxies. This derivation does not require any gravitating matter beyond the observed baryonic matter. The theoretical Rotation Curves (RC), resulting from these relations, fit observed RCs. We obtain these results by examining the interplay between the local gravitational energy density, around a galaxy, and the CMB energy density. This interplay causes the inhomogeneous and anisotropic space expansion around a galaxy.

You are on the right track

As for the BBT, what can I say?

A theory built on weak ad hoc foundations.

Modern science papers are written in a way to distance themselves, although many are written under control and direction of projects funded for the BBT.
