It is hypothesized that,at low temperature,though atomic nuclei are made of 2-flavored nucleons(i.e.,nucleon matter as nuclear droplet),strongly interacting matter(i.e.,gigantic nucleus)with baryon number from A(≈)103-9 to～1057 would be composed of 3-flavored strangeons if Nature favors always the flavor symmetry of quarks.According to that logic,strangeon matter with A～1057 could manifest in the form of pulsar-like compact stars,and multi-messenger observations with advanced facilities(e.g.,China's FAST)could eventually provide a dis-proof/proof.It is worth emphasizing that this point of view,based on established"old physics"(i.e.,the standard model of particle physics),may have particular consequences for understanding our material world,for both normal luminous matter and even the dark sector.
