The Resolution of the Twin Paradox in a One-Way Trip

Authors: Rodrigo de Abreu, Vasco Guerra

The twin paradox is considered in a one-way trip. Usually it is considered in a two-way trip. In the usual formulation, the problem, the relative ageing of the twins during the one-way trip, is hidden by the total ageing of the twins in the round trip. It is shown that if we know the relative ageing of the twins during the one-way trip there is no paradox and therefore the allegedly necessity to consider acceleration or the change of the frame argumentations does not emerge. It is also shown that the problem of simultaneity is irrelevant since in a one-way trip the twin can age slower or faster than the stay at home twin and therefore the asymmetry must have an explanation different of the standard explanation based on the time dilation effect. It is shown that Special Relativity is enough to solve the twin paradox. The twin paradox is a classical case of a not well formulated problem (an ill-formulated problem)
