Our Place in a Vast Universe *
Scientists have measured that what we can see of space is about a billion billion billion billion billion billion billion billion billion (10 81) times the volume of an average human. Inflationary theory suggests that the entirety of space is vastly larger. Quantum theory suggests that there are very many different copies of space of the same basic kind as ours (same laws of physics). String th...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Cosmology in a brane-universe
The purpose of this contribution is to present a new approach to extra-dimensions, the “braneworld” scenario, where ordinary matter is trapped in a three-dimensional surface, called ‘brane’, embedded in a higher dimensional space. This idea must be contrasted with the traditional Kaluza-Klein treatment of extra dimensions, where matter fields live everywhere in compact extra dimensions and can ...
متن کاملGravitation and cosmology in a brane-universe
Recent theoretical developments have generated a strong interest in the “brane-world” picture, which assumes that ordinary matter is trapped in a three-dimensional submanifold, usually called brane, embedded in a higher dimensional space. The purpose of this review is to introduce some basic results concerning gravity in these models and then to present various aspects of the cosmology in a bra...
متن کاملCosmology and Cosmogony in a Cyclic Universe
In this paper we discuss the properties of the quasi-steady state cosmological model (QSSC) developed in 1993 in its role as a cyclic model of the universe driven by a negative energy scalar field. We discuss the origin of such a scalar field in the primary creation process first described by F. Hoyle and J. V. Narlikar forty years ago. It is shown that the creation processes which takes place ...
