Cosmology Definition and 917 Threads

I am searching for a complete and extensive reference (or a reference set) about cosmology. It should be up to date and, if possible, with not too much formulas without proofs. It seams there are two classical books: Principles of Physical Cosmology, Peebles. Cosmological Physics, Peacock...

Newton was separate from his clockwork universe; in the last century we have realized that we experimenters really subjectify the outcome of our experiment by attempting to exclude ourselves from it. Both quantum mechanics and cosmology involve an observer who participates by disturbing an...

Hi all, I'm looking for a good review on how string theory accounts for inflation. I found a great review on 'classical' inflation by Linde explaining the paradigms in terms of GR and scalar fields but am looking for a good introductory review in terms of the string paradigm. I'm hoping to...

so the farther we look the more redshift we see in distant galaxies, but the farther we look the farther in time we look as well. so in other words, the farther back in time we go the faster galaxies appear to be moving away from us - the closer in time the slower...wouldnt' that implicate a...

http://arxiv.org/abs/astro-ph/0401136 The theory of Self Creation Cosmology is described and found to be as concordant as the standard cosmological 'concordance model' with local experiments and cosmological observations. However it does not require the speculative hypotheses of inflation...

I want to pursue for a Ph.D in these area.

Does anyone know if VSL theories are being seriously researched, studied, and pursued? -Glenn

Some new names (new to me anyway) Shinji Tsujikawa (has published with Robert Brandenberger, background in string research now interested in loop gravity) Roy Maartens (also string background, has published with Ellis) Parampreet Singh (one of the new LQG people in India) "Loop quantum...

How do we know that the physics we can do in labs here on Earth today is the same physics in galaxies a long time ago and far, far away? Take a collection of your favourite theories - the gravity of Newton, the electromagnetism of Maxwell, the quantum world of Schrödinger and Heisenberg...

In this theory a theoretical model is constructed for observation. (This is the first of a series) A: Space devoid of matter. B: Matter devoid of space. C: Space and Matter. In reply to "A" Is absolute space possible, a void with non-existing matter? has it been proven? can it...

An astronomy prof who teaches at a University in Iowa maintains a resource page of online astro java applets for students and general public to use and one of the applets is "cosmology calculator" http://www.earth.uni.edu/~morgan/ajjar/Cosmology/cosmos.html Here is her homepage...

Lineweaver(May 2003)--web's best cosmology tutorial http://nedwww.ipac.caltech.edu/level5/March03/Lineweaver/Lineweaver_contents.html I've been using Ned Wright's (UCLA astronomy dept) cosmology tutorial and FAQ a lot, but this new one is even better for some things---more up to date...

What I suspect is a major paper by Ashtekar (and others) appeared in arXiv this month----on June 9. Mathematical structure of loop quantum cosmology Ashtekar, Bojowald, Lewandowski arXiv:gr-qc/0304074 http://www.arxiv.org/abs/gr-qc/0304074 Here is the concluding paragraph: "We...

http://www.arxiv.org/abs/astro-ph/0202008 Here is a good overview of cosmology describing the evidence for the present model, the open questions, and what ongoing observations can be expected to resolve over the next decade. The writing is rigorous and for fellow profesionals (no effort at...

I would be thankful to you, if you tell me which book do you consider to be best, on the subject of cosmology, for: 1. Begineers 2. Intermediates 3. Advanced Thanks in advanced.

http://xxx.lanl.gov/abs/hep-th/9910146 This is only 16 pages and in PDF so easy to print out. It is by Fotini Markopoulou and Lee Smolin and it is called "Holography in a quantum spacetime" I nominate it for the landmark eureka paper of 1999. String theory and branes are on the run...

Is it true that for an isotropic, homogeneous flat universe with dust and a positive cosmological constant, the universe necessarily expands forever? The argument may be, (a_t/a)^2 = (8*pi*G/3)*rho + lambda/3 (Friedmann equation) where a_t refers to the first derivative of a with...
