In this work it is proposed a scientific line of reasoning called Lucernics which aims to describe natural phenomena in terms of properties of light. It also carries out an analysis about how gravity could be intermediated by virtual particles similar to photons, namely guardions. It also proposes that massive bodies are sinks of guardions. When a massive body absorbs guardions from vacuum fluctuations, dark guardions are emitted. A dark guardion is a virtual particle which carries momentum in a direction opposite to its displacement. The time-derivative of this momentum describes a possible attractive force between massive particles which emit them. This derived force was compared to Newtonian gravitational force and the caliber constant obtained was equal to Planck's mass. This same study was done for electrostatic force, obtaining Planck's charge as a caliber constant. Newton's gravitational constant and Einstein's field equation were decomposed, and it also proposes a Lucernic Field Equation. The phenomena that this equation could describe will be discussed in future works.
