Milky Way Galaxy

As for the fact that the Earth will be at the center of the Milky Way Galaxy, then I do not understand the meaning of this phrase. If you're talking about Milky Way, we are quite far away, on the outskirts of the spiral galaxy at a distance of approximately 30.000 light years away from the center. We rotate around the galactic center with a period of 225-250 million years, while approximately the same distance from it. Richard Linklater may find this interesting as well. Relative displacement of the poles, I also do not understand what it means. If it means a sudden change in position of the pole (ie, the axis of rotation of the Earth), it is not possible, as It was noted in the answer to Question 10. What is being discussed on many websites, is to build a series of (the parade), Earth and Sun and the center of the Milky Way in Sagittarius (Sagittarius). KDP is a great source of information.

It happens every year in December month, without any adverse effects, and there is no reason to expect that 2012 will be something different from other years. 12. When the sun and Earth line up in one line on the galactic plane with a black hole, located in center, can it lead to any serious consequences, because the black hole has such strong gravity? In the center of our Milky Way galaxy is a giant black hole, and as any cluster mass, strength of its gravitational effect on the rest of the galaxy. However, the center of the galaxy is far away, a distance of about 30.000 light years, so the impact of the black hole at the solar system and Earth negligible.
