| Time travel: A time travel is the traveling of one or more subjects from their respective present into a time which, from the point of view of these subjects, lies in the past or in the future. It is usually assumed that the traveler maintains their age and biological condition. Therefore, in the case of time travels, a hierarchy of several times is to be assumed, namely the proper time of the travelers which determines their biological age, the duration of the procedure of the travel and the historical time of the "destination". Logical problems associated with time travel are inter alia contradictions related to the fact that events of the past could be influenced after they occurred. See also time, time reversal, symmetry, time arrow, grandfather paradox._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

John Gribbin on Time Travel - Dictionary of Arguments
Gribbin II 210 Time Travel/Relativity Theory: those time travels that are allowed by relativity theory will lead to a distortion of the the structure of space-time so that the time axis in a local area in a direction corresponds to one of the three spatial directions in the undistorted area. An originally spatial direction then plays the role of the time. In the vicinity of a particular pulsar, this must be the case. >Relativity theory, >Space curvature, >Space time. Gribbin II 217 Time/existence/backward/time reversal/Gribbin: it may be that a non-existent photon creates a positron-electron pair, which then annihilates itself to produce the photon that first created the two particles ((s) Because of the photon time does not pass, there is no difference between past and future). >Time reversal, >Time, >Past, >Present, >Future,_____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
