Hypersphere World-Universe Model: Centre of Our Galaxy

Measuring our Universe from Galaxy Redshift Surveys

Galaxy redshift surveys have achieved significant progress over the last couple of decades. Those surveys tell us in the most straightforward way what our local Universe looks like. While the galaxy distribution traces the bright side of the Universe, detailed quantitative analyses of the data have even revealed the dark side of the Universe dominated by non-baryonic dark matter as well as more...

The Story of Galaxy Formation in Our Universe : The Onset of Galaxy Formation

The Cosmological Foundation of Our World, seen in a Revised History of our Universe

This paper has two parts, for a specific multiverse, and for the origin of our universe as it resulted from that multiverse. The first is based on the Planck domain and a Chandrasekhar equation that have quantum, relativity, gravity, and atomic physics in unified operation. The multiverse is an evolutionary system whereby universes survive only when they have those physics, and nearcritical mas...

Fe b 20 04 An hypersphere model of the Universe – The dismissal of dark matter

One can make the very simple hypothesis that the Universe is the inside of an hypersphere in 4 dimensions, where our 3-dimensional world consists of hypersurfaces at different radii. Based on this assumption it is possible to show that Universe expansion at a rate corresponding to flat comes as a direct geometrical consequence without intervening critical density; any mass density is responsibl...

Is Our Universe Brany ?

Brane-world models, which have received a lot of attention during the last few years, are essentially characterized by two basic ideas: • they assume the existence of spatial extra dimensions, in addition to our four space-time dimensions. The higher dimensional spacetime is usually called the “bulk” spacetime; • our accessible Universe is assumed to be a submanifold, called “brane”, embedded i...
