A quark star is a hypothetical type of celestial object that is composed entirely of quarks, which are the fundamental particles that make up protons and neutrons. It is believed that these stars may form when a neutron star collapses under its own gravity.
Quark stars are different from other types of stars because they are made up of quarks rather than the usual combination of protons, neutrons, and electrons. They also have a much higher density and stronger gravitational pull than other stars.
Scientists study quark stars through various methods, including theoretical calculations and observations of other celestial objects that may be related to quark stars, such as neutron stars and black holes. They also use advanced telescopes and detectors to search for evidence of quark stars.
Some of the mysteries surrounding quark stars include how they form and how they are different from other types of stars. It is also unknown whether quark stars actually exist, as they have not yet been directly observed or confirmed.
If quark stars are discovered, it would provide a deeper understanding of the fundamental building blocks of the universe and the extreme conditions that can exist in space. It may also have implications for our understanding of gravity and the structure of neutron stars and black holes.
