If time travel was at all possible we would be inundated with tourists from the future.
Even if you could hypothetically 'travel' in time the spatial navigation would be a bit of a problem. Even if you maintained your initial inertial frame of reference.
Where exactly was the Earth ten years ago say or even ten seconds? What is your reference frame for spatial position?
The equator moves at about 1600 km/hour due to the Earths rotation. 0.5 km/sec
The Earth goes around the Sun. 30 km/sec
The Sun orbits the Galactic centre. 250 km/sec
Our galaxy is moving relative to other nearby galaxies. 300 km/sec
Our local group of galaxies are moving relative to others. ?>300 km/sec
And so on.....
Actually we are all time travelers as we are moving into the future at 1 sec/sec.
