In [[The Sciences|science]], '''matter''' is commonly defined as the substance of which physical objects are composed, not counting the contribution of various [[energy]] or force fields, which are not usually considered to be matter per se (though they may contribute to the [[mass]] of objects). Matter constitutes much of the observable [[universe]], although again, light is not ordinarily considered matter. Unfortunately, for scientific purposes, "matter" is somewhat loosely defined. It is normally defined as anything that has mass and takes up space.
