Comment on Time travel doesn't work unless you also have teleportation. If you travel to the past/future, Earth will be in a different position in its orbit, and you'll die in space.

Everything else.

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 is expanding. 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).
