Right, I understand that we won't see a change in something that is 27,000 light years away for another 27,000 years. I guess the question should be, how quickly would the changes in the geography of the Milky Way happen? In other words, suppose a given star is 15,000 light years from the center of the Milky Way. Will it start drifting out more then 15,000 light years from the center the very second the black hole disappears or will it take longer for it to lose its gravitational attraction and drift out?
