There is not a single iota of evidence that large-scale planetary alignments cause changes in geologic events – like earthquakes and eruptions – on Earth. The only celestial bodies that could play some role – and there is some evidence that suggest that they may, in minor ways – are the Sun and the Moon. This is due to their relative close proximity (especially the moon) and their mass. I’ve covered some of this in my discussion of why the so-called “Supermoons” are silly and play no role in increasing/decreasing geologic events. What about the alignment with the galactic center? The center of the galaxy must exert some force on the Earth (and solar system) or we wouldn’t be orbiting it. However, beyond that fact that alignments like this happen all the time, the force that the galactic center exerts on Earth is ~0.00006x that of the Moon on Earth and ~0.00000037x that of the Sun, doesn’t it seem a little ridiculous to claim that the galactic center can change anything on Earth if the Sun and the Moon cause little-to-no effect on geologic events?

4 ways to use Wikipedia (hint: never cite it) Teachers: Please stop prohibiting the use of Wikipedia 20 Little Known Ways to Use Wikipedia Study: Wikipedia as accurate as Encyclopedia Britannica Schiff, Stacy. “Know it all: Can Wikipedia conquer expertise?” The New Yorker, February 26, 2006 And: Yes students, there’s a world beyond Wikipedia **Several years ago, Nature magazine did a comparison of material available on Wikipedia and Brittanica and concluded that Brittanica was somewhat, but not overwhelmingly, more accurate than Wikipedia. Brittanica lodged a complaint, and here, you can see what it complained about as well as Nature’s response. Nature compared articles from both organizations on various topics and sent them to experts to review. Per article, the averages were: 2.92 mistakes per article for Britannica and 3.86 for Wikipedia. -0- Follow The Answer Sheet every day by bookmarking http://www.washingtonpost.com/blogs/answer-sheet.
