Physics Of The Universe 1st Edition by Mendel Sachs (PDF)

Description

This book presents a new approach to the subject of cosmology. It fully exploits Einstein’s theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an explanation for the separation between matter and antimatter in the universe. There is a brief discussion of black holes and pulsars. The final chapter delves into philosophical considerations such as the different types of ‘truth’, positivism versus realism and a discussion of the role of the Mach principle in physics and cosmology.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐This and exciting alternative to the beautiful m theory cyclic universe proposed by Steinhardt. It has much the same approach as Roger Penrose (the similarity is strong in many ways.)Sachs uses spinors and quaternions where Penrose uses twistors…both are abstract realists and their theories are field rather than particle oriented.Even though I have a soft place in my heart for some indeterminacy I think his approach is well worth reading.

⭐First, the book itself was delivered in excellent condition. Dr. Sachs depicted some of his quaternionic field formulation of General Relativity in this well-written popular science book. There are only a few equations. More important are the philosophical concepts regarding the new concepts found by Dr. Sachs.

⭐本書を読んで目からウロコが落ちる思いをした。現行の宇宙論は、ビッグバンによって宇宙が誕生して膨張を続けているのだと教えている。しかし、普遍性を主張する一般相対論の立場からすると、時間の流れに異常を許すビッグバンは認めがたいことになる。著者は、一般相対論の原点に立ち戻って考察を進め、宇宙は膨張（その開始時がビッグバンに相当）と収縮を交互に繰り返す”振動宇宙論”を展開している。つまり、ビッグバンは何度でも起きるというわけ。この新しい宇宙論を支える十分な物理的考察と数学的根拠が提示されていて極めて興味深い。
