Theory of relativity:
The theory of relativity describes the relationship between space and time. It was developed by Albert Einstein in the early 20th century. A. The special theory of relativity (1905) The laws of physics are the same in all uniformly moving reference systems. This means that the laws of physics are equally valid whether you are at rest or in uniform motion. The speed of light in a vacuum is the same for all observers, regardless of the movement of the light source or the observer. - B. General theory of relativity (1915) This takes into account the distribution of masses and describes gravity as the curvature of space-time. See also space, time, spacetime, curved space. _____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Richard Feynman on Theory of Relativity - Dictionary of Arguments
I 117 Relativity Theory/Einstein/Feynman: every thing that has energy also has mass. Mass in the sense that it is subject to the gravitational effect. Even light that has energy, has a "mass". I 217 Def Relativity Principle/Newton: "The movements of objects within a given space are the same in relation to one another, whether the space is at rest or whether it moves constantly on a straight line." I 218 Feynman: the Newtonian laws appear to be the same in a uniformly moving system. Cf. >Theory change, >Meaning change. I 235 Twin Paradox/Feynman: one might think: If by the movement of one twin that one ages more slowly, that because of the relative movement of the two to each other both should actually "become younger"? Cf. >Relativity theory/Bergson. FeynmanVs: there is an asymmetry in the twin paradox: the man who experiences the acceleration at the start and at landing is the one who ages more slowly. The other one is in a completely different situation. Only the one who has moved can come back. That is a difference between them in an absolute sense and it is also true. >Absoluteness._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
