Physics
- Outer space, especially the relatively empty regions of the universe outside the atmospheres of celestial bodies
- Vacuum, a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure
- Free space, a perfect vacuum as expressed in the classical physics model
- Vacuum state, a perfect vacuum based on the quantum mechanical model
- In mathematical physics, the homogeneous equation may correspond to a physical theory formulated in empty space
- Void, empty space.

Famous quotes containing the word physics:
“The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.”
—Erich Fromm (1900–1980)
“The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.”
—Nancy Cartwright (b. 1945)
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
