Remember when Nana posted about the vision or most likely memory of being in space battling a huge black mass that made our satan look like a choir boy?
It was not a human or body type species but more like a mass of indescribable evil.
I am now thinking that this is what Juan is explaining as dark matter.
I believe it is an age old ancient on going battle, but our wining this battle for Earth's control and returning Earth to Adam's seed has a direct affect on the Universe battle against this mass of darkness evil.

Wow, there's a concept! Everything must be named, even this dark energy. Listening to Juan now, thanks!

This is what Gene Decode has been saying too, its A.I. that has been destroying several planets / galaxies ... the sentient black goo that is aware of itself ... this is why the Pleadians and Andromedia's among many others are also committed to cleaning this. Alec Collier said that many Light Entities (children) think of Earth as a "bad neighborhood", dangerous and evil.

The good news is most of us are awake, perhaps even aware and willing to go through this battle.

Someone else made a comment that rings true too, MedBeds are designed for light beings, if we are compromised with heavy metals it may jeopardize our systems for healings, unless it can remove the metals, hope so.
