Let suppose we have a frame of reference, in which a particle is decribed by [tex] \vec{x}(t) [/tex]...I don't give, on purpose, the context, if it is a classical framework, or a relativistic one...(Like somebody new, that does not even know what those word mean)...The question is : does this trajectory, which is, after some discussion with the non-knower, as seen (or oberseved or measured ??..not measured, because this would mean a radar like method...at least I suppose) by an observer at the origin, hence at x=0. So the question is : does this take into account the delay imposed by the speed of light limit, after another discussion with the same person who has to give an answer to the question ?(adsbygoogle = window.adsbygoogle || []).push({});

Do you think it takes the delay into account ?
