The strangelet forms what is called a nuclearite core, composed primarily of a up, down, and strange quarks, in almost equal proportions. Nuclearites are estimated to have masses between 0.1 and 100 kg. Additionally, they are predicted to be more stable than particles composed of solely up and down quarks. Nuclearites are expected to have a constant matter density. The hypothesized source of these particles are relics from the early universe or the big bang, as well as extreme energetic astrophysical phenomena such as the merger of two quark stars.
