Honestly, as soon as a heard it was astrology, like Feign, I closed out. Astrology isn't a real science and some people would call all the things that people who believe in it do total garbage, and that's what it is. I have no worry about this, and I will anticipate it and wait until we prove everyone wrong.
Also, the moon effects tides, not tsunamis >____>
Well, the sun and the moon both of a gravitational affect on the tides and the Earth itself.
Both are so weak that they really do nothing regarding anything other than water. The moon being closer for a small amount of time won't change anything. The tides might get a centimeter higher. Oh no.
However, in Earth's early history, the Moon was so close that the tides were tsunamis. But as time goes on, the Moon gets further away.
Eventually, we will no longer have a moon. That will happen in..I don't remember the numbers, but I know the sun will become a red-giant and swallow the inner solar system before it is supposed to happen. So, no worries there!
