Penrose’s Cyclic Cosmology

Penrose’s Cyclic Cosmology

Most distance object seen in Universe

The most distant object seen in universe was detected in April 23 by NASA Swift satellite.

A Gamma ray burst detected in redshift of 8.2 is the farthest object ever seen.

GRB 090423 was seen when it is about 630 million years after big-bang!!!

LHC Starts!!!

Finally after a two decade scientific planning and work, today the Cern Large Hadron Collider /near Geneva in the border of France and Switzerland/starts it works.

This tremendous,huge scientific projects, I think, must be included in the new eras one of world 7 wonders list.This super collider in energy and dimensions /27 km in circumstance tunnel /is the biggest one ever build, reaching to energy scales of TeV,which will be suitable for physicist to trace the physics beyond standard model.

There is a great hope to find the missing golden part of standard model the higgs boson.

Although there is chances in finding light supersymmetric particles/LSP/ which theoretically are presented as Dark Matter candidates.

The opening experiment excitement of LHC is reflected well in cosmic variance live blog.

Even today the Google changes its logo in honor of this human achievement.

Now there will be opened a golden era for particle physics phenomenologists to grasp the next decades Nobel prizes.

What is LHC?

Cosmology a monumental work by Weinberg

Steven Weinberg is really a great TITAN standing in the edge of new physics.

In April 2008, Steven's new book in cosmology which named briefly COSMOLOGY is printed by Oxford university press.

What a huge ,tremendous work,like his last decade Quantum field theory books ,this one is an encyclopedia too.

Weinberg claims that he tried to cover the most advanced research areas of cosmology up to 2007 also in the introduction he mentioned that after 1999 as he finished the QFT 3 volume work he had a plenty of time studying cosmology,he read the review articles but not satisfied with them,He drives all the cosmology by himself!!!

It starts from Accelerating universe to Gravitational microlensing,what a work!

Andrei Linde from Stanford declare:

"A monumental book written by a leading authority in particle physics and cosmology. Since publication of Weinberg's famous book Gravitation and Cosmology 35 years ago, there has been a real revolution both in cosmological theory and observations. A major effort of a great expert has been required to summarize the main developments in one book, and to make this presentation both highly accurate and accessible. This book will be greatly appreciated by a broad readership, ranging from students who just enter the field to experts in modern cosmology. It should be on the desk of every actively working cosmologist."

Robert Kirshner from Harvard

"This book tackles the main events of today's cosmology: cosmic acceleration observed with supernovae, the exquisite structure of the cosmic microwave background, and the evidence for dark matter. Weinberg pays close attention to the historical development and summarizes the observations with care. He brings deep knowledge of the underlying physics and weaves these threads together into a rich text that will be of great value to astronomers and physicists. The first half of this book is a wonderful introduction to cosmology, suitable for a graduate course or for someone coming into the field from a neighboring region of the scientific forest. The second half is an original development of the theory for the growth of inhomogeneities in the Universe. Everyone who works on cosmology will find something to learn in this book."

Anyhow today I start my journey through Weinbergs Cosmology!!!

A course and a book.

In 2008-autumn there will be a course in cosmology in Perimeter Institute thought by

Niayesh Afshordi, and Mark Wyman, from Perimeter Institute.

The course is based upon the T. Padmanabhan great book

Cosmology and astrophysics through problems ,published by Cambridge University press.

Although the course presenters change the place of astrophysics and cosmology in title, but they

describe in their course description that:

"This course is aimed at advanced undergraduate and beginning graduate students, and is inspired by a book by the same title, written by Padmanabhan. Each session consists of solving one or two pre-determined problems, which is done by a randomly picked student. While the problems introduce various subjects in Astrophysics and Cosmology, they do not serve as replacement for standard courses in these subjects, and are rather aimed at educating students with hands-on analytic/numerical skills to attack new problems."

Anyhow I take this book from library too and try to keep my paste harmonised with the course

presented in Perimeter and Waterloo physics department.
