A masterly overview of the development of cosmological thinking from the Greeks, via Newton and Einstein, to the present day. It is science's last and greatest challenge: fathoming the depths of the night sky. The objective: to crack the cosmic code, to unravel the blueprint for nature's grandest conception, a machine constructed on an unimaginably vast scale - the Universe itself. Today's model of an expanding Universe - the big bang cosmology - is actually built on principles derived from a few simple mathematical equations. Gravity-warped space time, quantum mechanics, the physics of the subatomic, these crucial insights, stemming from Einstein's revolutionary theories of relativity, have led to a simple and elegant framework within which the whole of the Universe, over billions of years, has been described. But recent evidence has begun to make wrinkles in the neat fabric of the big bang cosmology. There is now overwhelming evidence that there is far more stuff in the Universe than we can see. What, and where, is this 'dark matter'? And it now appears that the expansion of the Universe is accelerating: something out there - some exotic 'dark energy' - is acting against gravity to push space and time apart. While offering a critical view of how all the pieces in our current model fit together, Pedro Ferreira argues that Einstein's Universe may be just another stepping stone towards a new, more profound and effective cosmology in the future.
With these preferred directions present, it cannot be isotropic. recollapse, then it is said to be closed. A flat universe lies at the point of division between the open and closed possibilities. In a flat universe, expansion continues ...
A non-technical account of recent astronomical research makes all that is known about the universe accessible to the average reader, in a study that integrates scientific personalities with hard facts, vivid explanations, and authoritative ...
Davies (2003) gives an amusing and readable discussion of such possibilities. Section 30.7 30.19. See Penrose (1969a); Floyd and Penrose (1971). 30.20. See Blanford and Znajek (1977); Begelman et al. (1984). See also Williams (1995, ...
Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.
The Two State Universe
Lively and authoritative, this survey by a renowned physicist explains the formation of the galaxies and defines the concept of an ever-expanding universe in simple terms. 1961 edition. 40 figures.
Inspired by Einstein, Coltrane put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander follows suit, using jazz to answer physics' most vexing questions about the past and future of the universe.
The book also includes web links for all major news stories, providing a bridge between the public news stories and the actual research web sites.
Mack looks at five ways the universe could end, and the lessons each scenario reveals about the most important concepts in cosmology. --From publisher description.
She has contributed to the design and content production of educational games, professional development courses, and science workbooks. In essence, this is not a book written by a physicist for other physicists.
