Evidence of matter of an unknown and dark nature in human bodies

It is hypothesized that human bodies are coated in an unknown and dark substance. The article collects some data on a singular phenomenon that would prove the discovery of unknown and dark matter in human bodies. The data that is brought to support the aforementioned thesis are sounds in the audible range, produced at head level when, in appropriate conditions, the muscles of the head of the author of the work are put under tension. The action of holding the muscles can also stimulate this unknown matter, which reacts elastically for a few moments, interacting with the muscles, after which an audible noise is emitted. This action is carried out by the author of the article on a large part of the head muscles up to the shoulders. In other parts of the body, the substance is perceived occasionally, without any voluntary interaction. The phenomenon can be studied with the scientific method, as it can generally be produced and sound intensity measurements can be carried out.
