Cosmological implications of the Machian principle
Naturwissenschaften, 2006The famous idea of Ernst Mach concerning the non-absolute but relational character of particle inertia is taken up in this paper and is reinvestigated with respect to its cosmological implications. From Thirring's general relativistic study of the old Newtonian problem of the relativity of rotations in different reference systems, it appears that the ...

Cosmology without a cosmological principle
Lettere Al Nuovo Cimento Series 2, 1979where F ~ is the symmetric pa r t of the affme connection. Under this restr ict ion (rcf. (~)) only one spherically symmetric, s tat ic solution of the field equations appears to be physical ly meaningful namely the one for which the only non-zero, skew-component of the fundamental tensor g~ is g~s.

Cosmology, Mach's Principle and Relativity
American Journal of Physics, 1963The significance of Mach's principle (and the implicit relativity principle) for field theory is discussed, also the significance of zero-mass boson fields for the geometry of the physical space. The significance of such fields for Mach's principle within the framework of cosmology is also discussed.

Mathematical Proceedings of the Cambridge Philosophical Society, 1955
Many models of the universe have been proposed, by de Sitter, Milne, Bondi and Gold, Hoyle and others. The observed data being insufficient, the models are usually based on some simple hypothesis. The simplest is the cosmological principle, namely, that apart from local irregularities the universe presents the same general aspect at every point. Milne (

Dirac's Cosmology and Mach's Principle
Nature, 1961THE dimensionless gravitational coupling constant with mp the mass of some elementary particle, for definiteness taken as the proton, is such a small number that its significance has long been questioned.

Cosmology, Life, and the Anthropic Principle
Annals of the New York Academy of Sciences, 2001Abstract: We discuss some ways in which the age, size, and structure of the Universe, together with the values of its defining constants, satisfy the necessary conditions for life. The implications for teleology and the existence of other universes are also discussed.

The Cosmological Uncertainty Principle
1999We are investigating light propagation through evolving cosmological dark matter distributions, in order to determine the magnification properties of the universe, particularly in the weak lensing limit.

Anthropic principles in cosmology
Vistas in Astronomy, 1993Abstract We give a brief description of the known distribution of living things and their characterisation as examples of organised complexity occupying a particular range of sizes and masses in the Universe. We show how the existence of complexity is associated with the large age and size of the Universe.
