Reply to comment by Anonymous-USA in So from what I understand Sagittarius a is in the Center of Milky Way. If any planets orbit this black hole would there be time dilation? by EarthInteresting9781

So on intergalactic level it would be a strategic time-advance to be as isolated from gravity sources as possible, right? For example a perhabs planet-sized ship with a highly advanced species leaving its galaxy-cluster to avoid encounters with other species

What??? I don’t know how you came to that conclusion. The time dilation is basically negligible unless very close to the gravity well, even if there is some residual effect past the event horizon or heliosphere (for a sun). In fact, there may be advantages in energy access closer to a major interstellar object.

So I doubt it would make any difference. Rather, any intergalactic species (even our own) would want to mathematically account for time dilation from both sources — velocity and gravity — when communicating data and positioning. Which we already do ourselves. GPS wouldn’t work without accounting for time dilation. So accounting for it, yes, strategically designing around it, unlikely imo
