For the sole 'property' of matter, with whose recognition philosophical materialism is bound up, is the property of being an objective reality, of existing outside of the mind. Lenin was developing the work of Engels, who said that "with each epoch-making discovery, even in the sphere of natural science , materialism has to change its form". [ 42 ]
Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate
Philosophy of matter is the branch of philosophy concerned with issues surrounding the ontology, epistemology and character of matter and the material world. The word matter is derived from the Latin word materia , meaning "wood", or “timber”, in the sense "material", as distinct from "mind" or "form". [ 1 ]
In regular cold matter, quarks, fundamental particles of nuclear matter, are confined by the strong force into hadrons that consist of 2–4 quarks, such as protons and neutrons. Quark matter or quantum chromodynamical (QCD) matter is a group of phases where the strong force is overcome and quarks are deconfined and free to move.
An intensive property does not depend on the size or extent of the system, nor on the amount of matter in the object, while an extensive property shows an additive relationship. These classifications are in general only valid in cases when smaller subdivisions of the sample do not interact in some physical or chemical process when combined.
A definition of "matter" based on its physical and chemical structure is: matter is made up of atoms. [17] Such atomic matter is also sometimes termed ordinary matter. As an example, deoxyribonucleic acid molecules (DNA) are matter under this definition because they are made of atoms.
Sphera volgare, featuring the Sun, the Moon, the winds and the stars as living. Woodcut illustration from an edition of De sphaera mundi, Venice, 1537.. Hylozoism is the philosophical doctrine according to which all matter is alive or animated, [clarification needed] [1] either in itself or as participating in the action of a superior principle, usually the world-soul (anima mundi).

In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. [1]
