Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.
Answer: it can help you (if you observe well) 1) to get to know yourself better, 2) recognize relating patterns adquired from your own family, 3) leave infantile approach to relationships (we all have tendency to look for someone who will unconditionally satisfy our needs and our ego requirements) and learn to relate as adult (respecting, i.e. respect frontiers of the other and require respect, i.e. learn the other respect your boundaries), 4) leave childish, infantile dependency and become responsible for the kind of relationships we make.
Explanation: in our psyche there is always something what is called "kinship libido" that seduces us again and again to regress, to depend on parenting figures. That is why it is no easy to leave family of origin (leave not only physically but also psychologically).
