I'm just wondering about time dilation in regards to both special and general relativity within our galaxy. Does time move slower or faster relative to us within the inner parts of the galaxy? I know at the horizon of the black hole time is effectively not moving. This implies that locations closer to the black hole will move slower in time. But we also see stars moving on the outer edge of the galaxy moving around the center of the galaxy with an equal angular velocity as the stars on the inner parts of the galaxy. Could this be explained by time dilation? Current theory uses dark matter to explain why the angular velocity of stars revolving around the center of the galaxy are moving faster than expected, but could it just be that they experience less gravity and thus feel less effect of time dilation causing us to see them moving faster since we are moving slower in time?
