Kjarnapunkturinn

Could you please specify what Kjarnapunkturinn refers to? The term could relate to different things (for example a concept in science, a place or building name, a work of art or literature, or a fictional concept). If you can share the intended meaning or any source you want covered, I can write a concise, neutral wiki-style article under 300 words. If you’d like, I can also draft a generic stub that explains the literal meaning of the term in Icelandic and outlines common ways such a term might be used in articles.
