**ELECTRICAL FLOW GIVES THREE TYPES OF PLASMA**

The are three types of mode of electrified plasma.

1, Dark Mode when the voltage is low so we don’t see anything but can still measure it (I though prefer to call it ‘invisible mode’ to differentiate from mystical substances like dark matter which can’t be in any way be detected or measured), just like radio waves which are not seen.

2, Glow Mode when there is an increase in power and we start to see it, like in a fluorescent tube.

3, When there is even more power and it arcs, like a lighting bolt or the surface of the sun as a arcing plasmoid. This is clearly seen in bipolar nebular with the Z-Pinch clearly in effect by constricting the ionized gas and then making it glow.

**SATURN’S ELECTRIC MOON ENCELADUS**

It was reported and confirmed this week that the mainstream scientific community are as much in the dark as they have ever been. So once again we must ask, is this more evidence of ignorance in the main stream because they have been blinded by quasi religious doctrine and tenet?

To me this is probably the reason for most, which means that they should be just sacked without delay so they can give up on science, go back to school and learn some physics.

I haven’t touched on this for a while so in light of our electrically active earth environment and the amount of metal particulates in chemtrails that are being pumped into the atmosphere, I think we should once again remind ourselves of the phenomena.

Because of the size of their own self importance this wouldn’t even occur to them because apart from being able to do some complicated sums and spout unproven doctrine, there really isn’t too much else there. Personally I couldn’t watch much of the following video (about 15 mins) because I have heard it all before and it’s the same poor guess fiction and so is pointless and a waist of time in my life.
