Since the earth, and the whole solar system, along with the galaxy are moving through space, I can imagine some clever scientist discovering time travel, firing up they time machine, only to then find themselves in vacuum of space in a place the earth had long passed by already. Others try to calculate and predict the position. But they didn’t use enough floating point precision bits and ended up in the earth’s crust…

The friend asks if the scientist forgot the movement of the Earth and the galaxy, but the scientist assures him that no, that motion has been accounted for. Instead it appears they've arrived betwee…
