Wouldn’t everything be relative to the gravity influence?
When you would travel through time, it would make more sense that you appear in the future in the same spot relative to the thing holding you there now, the universe has no absolute X,Y,Z coordinates.
This is of course science fiction and up to your own interpretation. But, if you travel in time but not space, that means the earth is in a vastly different spot than it was before, even if there are no absolute coordinates to the universe. The earth travels around 140 miles per second relative to the center of the galaxy, so theoretically even a tiny time travel hop could mean you're appearing in the vacuum of space.
Ok so you're assuming the position stays constant while time travelling. As mentioned, there is no absolute xyz, so whoever made the time machine had to choose a frame of reference in which the position would stay constant. The logical thing to do would be to take the frame of reference of the earth, and so time travel wouldn't cause any issues.
And that galaxy rotates on itself. And that galaxy also has an elliptical movement within a cluster, which is moving within a super cluster, and so forth.
