Δεν απαιτεί big bang και φαίνεται ότι ταιριάζει καλύτερα στα παρατηρησιακά δεδομένα, εξηγεί την επιταχυνόμενη διαστολή, χωρίς τη χρήση σκοτεινής ενέργειας, όπως και μερικά ακόμα προβλήματα της κοσμολογίας..

Abstract
In the late 1990s, observations of Type Ia supernovae led to the astounding discovery that the universe is expanding at an accelerating rate. The explanation of this anomalous acceleration has been one of the great problems in physics since that discovery. In this article we propose cosmological models that can explain the cosmic acceleration without introducing a cosmological constant into the standard Einstein field equation, negating the necessity for the existence of dark energy. There are four distinguishing features of these models: 1) the speed of light and the gravitational "constant" are not constant, but vary with the evolution of the universe, 2) time has no beginning and no end, 3) the spatial section of the universe is a 3-sphere, and 4) the universe experiences phases of both acceleration and deceleration. One of these models is selected and tested against current cosmological observations of Type Ia supernovae, and is found to fit the redshift-luminosity distance data quite well.
