Is fourth density a wormhole?

[Questioner]

Sorry about the tangent. My point is that I'm really wary about that particular source and their emphasis on "people with knowledge," as though hidden knowledge, cleverness and study are the keys to enlightenment. Ra specifically said that we are in a density that is not one of understanding, that our spiritual growth is from healing ourselves and having unity between each other... which is not dependent on ingenuity or research. If you like I will edit or pull my post, you can edit your response and we can clear out the tangent.
