What is the most precious substance in space?

The most precious substance is the universe is probably a Quark-Gloon plasma or something similar. It is a phase of mass generated only at the most intense temperatures and pressures. For most of the first million seconds after the Big Bang, an explosive event that created our universe was in all mass in the form of a Quark-Glon plasma. Quarks and gluons are particles that make up nucleons such as neutrons and protons, which in turn form atoms that make up all the mass. Quarks are particles with matter, while gluons are force particles that "stick" together. Kvark-Gloon plasma is a bathtub of almost free quarks and gluons, which are usually firmly locked in nucleons. Conventional nucleons are so firmly held together that even a nuclear explosion or temperature and pressure on the core of the sun is not enough to divide them. Free quargs have never been observed and some physics think that the phenomenon of free quarks is physically impossible.

Quark-Gloon plasma is created in some unusual circumstances outside the Big Bang. Since 2000, we have been able to produce it at will in particle accelerators using a huge amount of energy focused on heavy ions. It took about two decades an attempt to create it, the most precious substance we know. The act was achieved in the CERN particle accelerator in Switzerland. More recently, Cern's Great Hadron Collider performs experiments on the Quark-Gloon plasma.

Quark-Gloon Plasma may not actually be the most precious substance if it turns out that there is extremely massive stars in the middle. Some neutron stars (the rest that left some of the largest supernova) divided by theories, causing some scientists suspecting they are not neutron stars, but in fact Quark Stars. Neutron stars have a radius between 10 and 20 km (6-12 miles), but the weight slightly larger than in the sun. Quark, on the other handBetween 3 and 9 km (2-6 million) and weight comparable to neutron stars, which makes them the worst objects in space. The rest of the supernova RX J1856.5-3754, the neutron star closest to the country, is one of the potential candidates to be a star of quark.

There are other substances that are afraid of the title of the most precious substances in space. These include exotic particles created in collisions of space rays with very high energy and other exotic particles that existed at the dawn of the universe, but have never been seen since then. The antihhatter does not qualify as the most precious substance in the universe, as it can still be found floating in space practically everywhere, albeit in very low proportions.
