Abstract:
In this presentation we shall discuss the emergence of the gravitational interaction in recent cosmological theories based on scalar fields. After a short overview of the speculative domain, we plunge into recent theories, analyzing the possible influence of the background expansion due to the appearance of scalar fields in the corresponding action. Lastly, we confront our cosmological theory with recent data from cosmic chronometers, baryon acoustic oscillations, and supernovae.
