They (stars) provide the heavy metals that your body used to function. Stars provide heat, light, gravity…and more.
The world around us modifies all our Behaviors, starting from the response or reaction that happens in our Sensory Organs, which generate a physical and chemical change that translates into Nervous Impulses that are sent as data from this environment to the Brain, which analyzes , captures and reorders this information received in order to obtain a Sensory Perception that is what allows us to relate to the environment.
Thanks to this phenomenon is that we delight ourselves with all the wonders that surround us, we do all kinds of activities, from listening to music (through the sense of hearing) to the need to warm ourselves when we feel cold (using the sense of touch) so that it could be said that everything that happens around us is in charge of having a relationship of stimulation and response in a constant way.
In this world that amazes us, we not only delight with what we have close contact, but we also have the ability to Observe and Experiment, and one of the main obsessions of humanity is the analysis of the Stars and Celestial Bodies that are distributed in the area that is known as Outer Space.
One of the main characteristics that has a Star to be recognized as such is that it has a Own Luminescence, so it is possible to recognize them in the sky late at night, and that their combination can form different Polygonal Figures that are known as Constellations.
This grouping of stars has been important in its application to Astronomy, to be able to individualize and make precise locations of the different Celestial Bodies within the space, being able to even make an astral map and locate them depending on the Celestial Hemisphere where they are located, being perhaps those that more we know the constellations of the Signs of the Zodiac, although different constellations exist according to the cultures or the origin from where the observation of the sky comes.
