Q&A: Galaxies, Galaxy Clusters, AGN, and Quasars
If the Sun is moving through the galaxy at several hundred kilometers/sec. and the galaxy is also moving at about the same speed through the universe, could we send a spacecraft to a particular location "behind" us by causing it stand still with reference to the movement of the sun and the galaxy? Could we actually "stop" a spacecraft?
In principle it would be possible to "stop" a spacecraft with respect to
our galaxy, or other galaxies, by sending it in the opposite direction from
the motion of the Sun or the galaxy.
