What is dense matter?

We can say that gold is denser than aluminum because its density is 19.3 grams per cubic centimeter compared to 2.7 grams per cubic centimeter for aluminum.

Material with a high mass-to-volume ratio—that is, a lot of mass packed into a small amount of space—is referred to as dense matter. Extreme environments, like the cores of massive planets or neutron stars, are common places for this type of material to exist.

Dense matter refers to matter that is tightly packed together, typically with high mass per unit volume. It is characterized by high density, meaning a large amount of mass is concentrated within a relatively small volume. Dense matter is often found in extreme environments such as the cores of stars, neutron stars, and certain types of exotic matter. Examples of dense matter include degenerate matter found in white dwarfs, neutron degenerate matter in neutron stars, and quark-gluon plasma in the early universe or in high-energy collisions of heavy nuclei.
