what does the motion of the stars around the center of the milky way tell astronomers?
there are too many stars there.
there is a black hole there.
the sun is moving in that direction.
the milky way is dying.

Explanation:

Astronomers observe the motion of stars around the Milky Way's center. According to gravitational - dynamics, the high - speed and specific orbital motions of these stars suggest an extremely massive and compact object. A black hole, with its strong gravitational pull, can explain such stellar motions. The number of stars alone doesn't account for the motion pattern. The Sun's movement is a separate aspect not related to this motion - based inference about the galactic center. And there's no indication from stellar motion around the center that the Milky Way is "dying".

Answer:

There is a black hole there.
