The hypothesis is made that, at large scales where General Relativity may be applied, the empty space is scale invariant. This establishes a relation between the cosmological constant and the scale factor of the scale invariant framework. This relation brings major simplifications in the scale invariant equations for cosmology, which now contain a new term, depending on the derivative of the scale factor, that opposes to gravity and produces an accelerated expansion. The displacements due to… Expand
Dynamical Effects of the Scale Invariance of the Empty Space: The Fall of Dark Matter?
The hypothesis of the scale invariance of the macroscopic empty space, which intervenes through the cosmological constant, has led to new cosmological models. They show an accelerated cosmicExpand
Constraining alternatives to a cosmological constant: Generalized couplings and scale invariance
We present a comparative analysis of observational low-redshift background constraints on three candidate models for explaining the low-redshift acceleration of the universe. The generalized couplingExpand
Scale invariance, horizons, and inflation
Maxwell equations and the equations of General Relativity are scale invariant in empty space. The presence of charge or currents in electromagnetism or the presence of matter in cosmology areExpand
The Scale-Invariant Vacuum (SIV) Theory: A Possible Origin of Dark Matter and Dark Energy
The Scale Invariant Vacuum (SIV) theory rests on the basic hypothesis that the macroscopic empty space is scale invariant. This hypothesis is applied in the context of the Integrable Weyl Geometry,Expand
Scale-invariant Cosmology and CMB Temperatures as a Function of Redshifts
Cosmological models assuming the scale invariance of the macroscopic empty space show an accelerated expansion, without calling for some unknown particles. Several comparisons between models andExpand
Note on dark energy and cosmic transit in a scale-invariance cosmology
In general, the laws of physics are not invariant under a change of scale. To find out whether the 'scale-invariance hypothesis' corresponds to nature or not, a careful examination to itsExpand
Scale-invariant dynamics of galaxies, MOND, dark matter, and the dwarf spheroidals
The Scale-Invariant Vacuum (SIV) theory is based on Weyl's Integrable Geometry, endowed with a gauge scalar field. The main difference between MOND and the SIV theory is that the first considers aExpand
Astromechanics of Dual Universe: A New Possible Explanation for the Universe Unsolved Problems
The necessity of the dark energy and dark matter in the present universe could be a consequence of the antimatter elimination assumption in the early universe. Current cosmological models that relyExpand
A New Cosmological Model of a Spatial and Time-Reversal Couple Universe of Symmetrical Relativity
This study investigates the possibility of applying a new four-dimensional and positively curved model of a spatial and time-reversal Couple Universe to predict the expansion rate and the speed ofExpand

Precise astronomical measurements of the fine structure constant and universe expansion rate have revealed that they vary through specific directions, indicating an anisotropic universe. TheExpand


Scale Covariant Theory of Gravitation and Astrophysical Applications
By associating the mathematical operation of scale transformation with the physics of using different dynamical systems to measure space-time distances, we formulate a scale-covariant theory ofExpand
The Cosmological Constant and Dark Energy
Physics invites the idea that space contains energy whose gravitational effect approximates that of Einstein's cosmological constant, Lambda: nowadays the concept is termed dark energy orExpand
Constraints on the redshift dependence of the dark energy potential
We develop a formalism to characterize the shape and the redshift evolution of the dark energy potential. Our formalism makes use of quantities similar to the horizon-flow parameters in inflation andExpand
On the luminosity distance and the epoch of acceleration
Standard cosmological models based on general relativity (GR) with dark energy predict that the Universe underwent a transition from decelerating to accelerating expansion at a moderate redshiftExpand
Hints of dynamical vacuum energy in the expanding Universe
Recently there have been claims of model-independent evidence of dynamical dark energy. Herein we consider a fairly general class of cosmological models with a time-evolving cosmological term of theExpand
Cosmological constant and vacuum energy: old and new ideas
The cosmological constant (CC) term in Einstein's equations, Λ, was first associated to the idea of vacuum energy density. Notwithstanding, it is well-known that there is a huge, in fact appalling,Expand
