Quark (dairy product) considered to be different types of fresh cheese, while in Eastern Europe cottage cheese is usually viewed as a type of quark (e.g. Russian for cottage cheese is "зернёный творог" "zernyony tvorog", literally "grainy quark"). Quark is similar to French fromage blanc, Indian paneer, and the queso fresco/queijo fresco made in the Iberian Peninsula and in some Latin American countries. It is distinct from Italian ricotta because ricotta (Italian "recooked") is made from scalded whey. Quark is somewhat similar to yogurt cheeses such as the South Asian "chak(k)a", the Arabic labneh, and the Central Asian suzma or kashk, but while
Quark star Quark star A quark star is a hypothetical type of compact exotic star, where extremely high temperature and pressure has forced nuclear particles to form a continuous state of matter that consists primarily of free quarks. It is well known that massive stars can collapse to form neutron stars, under extreme temperatures and pressures. In simple terms, neutrons usually have space separating them due to degeneracy pressure keeping them apart. Under extreme conditions such as a neutron star, the pressure separating nucleons is overwhelmed by gravity, and the separation between them breaks down, causing them to be packed extremely densely
