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?

Conspiracy debunked: Atlanta snow doesn't melt. - 16 views

"Here at BA Central I see a lot of truly ridiculous conspiracy theories. Over the years there's been the Moon Hoax, various asteroids NASA was covering up that would hit the Earth (or wipe us out somehow via electricity), and of course the end of the Earth over and over and over again. Yet happily, we're still here. Yet sadly, so are these silly theories."
