Quark matter is a type of exotic matter that is theorized to exist at extremely high densities, where quarks—fundamental particles that make up protons and neutrons—are no longer confined within individual baryons (protons and neutrons) but instead exist in a free or deconfined state. This state of matter is expected to be found in the cores of neutron stars, particularly in neutron star mergers or in the early universe shortly after the Big Bang.
