Just a thought: when the earth tilts people swear its some sudden event and overnight swoosh south is north and north is south. It doesn't make any sense.
Instead what make sense is that she tilts slowly within her axis until the northern side is top heavy and completes the tilt. Like a ball spinning with moving mass inside.. With a slow tilt due to magnetics and or other: the water would re-adjust globally to accomodate, keep in mind magma is magnetically charged and would logically be part of fluid and gas shifts, so when the mass on one side of globe has reached a certain point the full tilt to opposite poles finishes. Its a journey. Not a Hollywood movie.
Thats my theory... Its a gradual visible tangible logical sequence with an intelligent system to sustain its position in axis. Etc.
Happy Thursday.
