what is the "density" exactly means?

[Peregrinus]

like
we 1d, we/me 2d, me 3d, me/we 4d, me/we 5d, we 6d.

perhaps

Positive path: we 1d, we/me 2d, me/we 3d, me/we 4d, me/we 5d*, we 6d.

*Because understanding of unity is the requirement for graduation to the 5th density, is it possible that 5D is 'we' only as well as 6D?

Negative path: we 1d, we/me 2d, me 3d, me 4d, me 5d, me/we 6d.

yes with the fine detail of the local logoi being able to modify the laws according to their preference, despite not being able to change core of the laws. (ie, various physics constants were discovered not to be same everywhere in universe)

I believe any law of physics as we know it may be changed by the Logos at any time, though is only done during regular intervals (as the striking of the clock upon the hour). As it currently is, there are a number of areas where our human brother scientists are currently perplexed.
