Gravity is universal and universally misunderstood. The recent programmes on the subject of cosmogyny put out by the BBC has a fundamental error in the first programme.

The narrator states that at the center of the star the gravity is so great that...blah blah.

Yet the basic concept of gravitational attraction is that mass attracts mass. An object in the center of gravity will be deemed weightless if attracted to all the other objects surrounding it.

Another way of answering the paradox of "where are the stars if we see them years after they move?", is to resolve the dispersal of gravity in a series of instantaneous reactions rather like the chain reaction called the domino effect.
