Black Hole in the Center of the Milky Way Galaxy

                     " Since the beginning of the observations in 1992 one of the stars, called S2, has now completed one full orbit. Its orbit (Sch ̈del et al. 2002;Ghez et al. 2003) has a period of 15 years. Since 2002 the number of reasonably well-determined orbits has grown from one to 28; in total we currently monitor 109 stars, see Figure 1."

This quote is from a recent report on 15 years of study.

I just realized that my son has been alive during all those years. So S2 went around the center of the galaxy in the time my son has gone from Mexico to Chicago.

He is not back in Mexico though : (
