In physics , a string is a physical phenomenon that appears in string theory and related subjects .. string theory. string theory. physics. physics. Unlike elementary particles , which are zero-dimensional or point-like by definition , strings are one-dimensional extended objects .. Theories in which the fundamental objects are strings rather than point particles automatically have many properties that some physicists expect to hold in a fundamental theory of physics .. physics. physics. Most notably , a theory of strings that evolve and interact according to the rules of quantum mechanics will automatically describe quantum gravity .. quantum mechanics. quantum mechanics. quantum gravity. quantum gravity
