Maybe if you timed it juuuuuust right you could land somewhere on the planet as it orbits the sun and comes back to the same position once a decade or century or whatever? I mean I guess it depends on how you determine absolute location in the universe. Is that even possible with the universe constantly expanding?
Nope, not possible. The solar system itself is moving as is the galaxy… it’s useful to think of Earth’s orbit as spiraling around the sun in the direction our star is traveling. So 1 orbit later we have not come to the same location.
Galactocentrism was established in 1925, which realised that our solar system is not near the center of the Milky Way. So, we are moving relative to the center of our galaxy.
In 1929, evidence was found that everything else is moving away from us. So we are moving relative to everything else.
In 1931, the Big Bang theory started superceding Galactocentrism, which was an acentrist model of the universe (where there is no center).

But moving relative to what?
Everything else.
