Princeton's WordNet

  1. relativity, theory of relativity, relativity theory, Einstein's theory of relativitynoun

    (physics) the theory that space and time are relative concepts rather than absolute concepts

  2. relativitynoun

    the quality of being relative and having significance only in relation to something else


  1. relativitynoun

    One of two theories (also called theory of relativity) proposed by Albert Einstein, the special theory of relativity, or the general theory of relativity. The special theory of relativity or special relativity is based on the proposition that the speed of light is a constant no matter how observed, and is independent of the motion of the observer. From this follows several principles, such as the increase of mass with velocity (which has been confirmed: see relativistic mass equation) and the impossibility of acceleration to a speed greater than that of light; the equivalence of mass and energy, expressed by the famous equation E = mc2; and time dilation, which is the apparent slowing of a clock in a system, as observed by an observer in a system moving relative to the clock. The general theory of relativity is based on the proposition that there is no physical difference between gravitational force and the force produced by acceleration. From this follow several results, of which the bending of light rays in a gravitational field and the equivalence of the inertial and gravitational masses have been verified. The possible existence of black holes (believed by many astronomers to have been adequately proven) is another consequence of the theory.


  1. relativitynoun

    The state of being relative to something else.

  2. relativitynoun

    The principle that the laws of physics should be the same for all observers.

  3. relativitynoun

    Either of two theories (special relativity or general relativity) developed by German-American physicist Albert Einstein. Also called Einsteinian relativity.

Webster Dictionary

Examples of relativity in a Sentence

  1. Baba Faiz:

    What if we use Einstein's special theory of relativity to freeze time? The reason is simple and precise. The idea of freezing time is to freeze our love; Love always young and charming.

  2. The wise Pharoah Moe:

    You urge time when you are expecting your salary, you urge time when you want to meet your beloved, you urge time when you wish to see your children grow up. And when time is urged, you astonishly exclaim! Maybe this is the true theory of relativity..

  3. Daniel Kennefick:

    It was no longer clear how to interpret variables in Newtons law of gravity in light of the discoveries of special relativity.

  4. Albert Einstein:

    When the Special Theory of Relativity began to germinate in me, I was visited by all sorts of nervous conflicts... I used to go away for weeks in a state of confusion.

  5. Andrea Ghez:

    Einstein's right, at least for now, we can absolutely rule out Newton's law of gravity. Our observations are consistent with Einstein's theory of general relativity. However, Albert Einstein theory is definitely showing vulnerability. It can not fully explain gravity inside a black hole, and at some point we will need to move beyond Einstein's theory to a more comprehensive theory of gravity that explains what a black hole is.
