What will happen when the planets align?

Answer 1

First, nothing would happen if all the planets were to line up. Each planet is so far from the others that the gravity from one planet is negligible on another.

Second, it is impossible for all the planets to line up. They all orbit in slightly different planes, and they will NEVER all line up. And never have.

Answer 2

December 21, 2012 has been called doomsday, the day of enlightenment, and even the day the earth will turn upside down by many different culture and civilizations throughout history. Although the prediction on what is actually going to happen is vague modern day scientists know we our planet is aligning with the galactic equator. Well what does that mean and what does it have to do with humanities future? In the milky way, which is an active galaxy, our solar system moves above and below this galactic plain. As stars and planetary systems, including our own approach this galactic plain the gravitational influence increases, which disturbs the stability of the planets, including earth. The passage through the most dense portion of the gravitational plain is the direct result of the devastation cycles and pole shifts that we see recorded throughout earths history. This distinct nature of our solar system is how many ancient civilizations based there calenders, which are incredibly accurate.

Although many of us have heard or are aware of the ancient Mayan calender, a lot of us either don't understand it or simple don't know how it works. Well to start the ancient Mayans had a very accurate understanding of our solar system and its cycles. Their long count calender is most significant of their calenders because according to Mayanist (people who study Ancient Mayan People and culture) it ends on the specific date of December 21 2012, which coincides with modern day astronomers, who believe that is about the time that our planet alignment takes place with the galactic equator.

Answer 3

Nothing detectable without very sensitive instruments.

Answer 4

Yes. They do every 640,000 years...
