In the realm of cosmology, extensions of the term matter are invoked to include dark matter and dark energy, concepts introduced to explain some odd phenomena of the observable universe, such as the galactic rotation curve. These exotic forms of "matter" do not refer to matter as "building blocks", but rather to currently poorly understood forms of mass and energy.
Matter is a general term for the substance of which all physical objects consist.Typically, matter includes atoms and other particles which have mass. A common way of defining matter is as anything that has mass and occupies volume.
In practice however there is no single correct scientific meaning of "matter," as different fields use the term in different and sometimes incompatible ways.
