We will never be moving to another "density". We will always be a 2nd Density planet. We will move up in dimensions, not density. 2nd density planets are evolutionary worlds with intelligent life. First density orbs are suns, moons etc.

We are already in 4th dimension. we cannot move into 5th dimension until society has built a 5d society. Which is one of global peace and certain technology advancement. when we are in 5d, our current electrical systems will NOT work, so before then we have to convert to energy systems that will work, get off the oil for energy etc.
