Dark energy without dark energy [PDF]
AIP Conference Proceedings, 2006 It is proposed that the current acceleration of the universe is not originated by the existence of a mysterious dark energy fluid nor by the action of extra terms in the gravity Lagrangian, but just from the sub-quantum potential associated with the CMB ...

Dark Energy and Dark Matter [PDF]
Physics Letters B, 2003 It is a puzzle why the densities of dark matter and dark energy are nearly equal today when they scale so differently during the expansion of the universe. This conundrum may be solved if there is a coupling between the two dark sectors. In this paper we

Evidence for Dark Energy Driven by Star Formation: Information Dark Energy? [PDF]
EntropyEvidence is presented for dark energy resulting directly from star formation. A survey of stellar mass density measurements, SMD(a), as a function of universe scale size a, was found to be described by a simple CPL w0 − wa parameterisation that was in ...

Information Dark Energy Can Resolve the Hubble Tension and Is Falsifiable by Experiment [PDF]
Entropy, 2022 We consider the role information energy can play as a source of dark energy. Firstly, we note that if stars and structure had not formed in the universe, elemental bits of information describing the attributes of particles would have exhibited properties

"Teleparallel" Dark Energy [PDF]
Physics Letters B, 2011 Using the "teleparallel" equivalent of General Relativity as the gravitational sector, which is based on torsion instead of curvature, we add a canonical scalar field, allowing for a nonminimal coupling with gravity.

Fingerprinting dark energy [PDF]
Physical Review D, 2009 Dark energy perturbations are normally either neglected or else included in a purely numerical way, obscuring their dependence on underlying parameters like the equation of state or the sound speed. However, while many different explanations for the dark

Physics Letters B, 2017 We build a model of metastable dark energy, in which the observed vacuum energy is the value of the scalar potential at the false vacuum. The scalar potential is given by a sum of even self-interactions up to order six.

Dipolar Dark Matter and Dark Energy [PDF]
Physical Review D, 2009 In previous work [L. Blanchet and A. Le Tiec, Phys. Rev. D 78, 024031 (2008)], a model of dark matter and dark energy based on the concept of gravitational polarization was investigated.
