So what effect will this have on earth? well the Mayans claim it will mark the end of this life cycle and the beginning of a new one. Scientists are not sure exactly what will happen but here are some theories of the possible effects.1. Planetary Polar shift: North becomes south. Not sure the effect this will have on earth.
2.Comets\Asteroids hitting the earth: One of these larger ones hits the earth it is a doomsday. Because of the extra and chaotic gravity going through our solar system it will play with the kuipler belt and send comets and asteroids in abundances into the inner solar system which raises our chances of being hit.
3.Earthquakes/volcanoes eruptions/dramatic weather: same effects they allready have but on a higher level.The extra pull on the planet may cause mother nature to go wild.
4.Sun flares: Possible sun flares on the earth could cause anywhere from a radiation poisining to the earth set to flames. The sun will all so be effected by going through the galactic plain.
These are only the top 4 theories of what might happen but there are many more.
What will happen we will have to what and see but it is best to prepare just in case something does happen.
