Thanks for the ping.
My assumptions about the sun are:
1. We don't know near as much as we think we know about it.
2. There are plenty of other 'gateways,' 'portals,' . . . for entities and even UFO's to materialize out of--from the 'evil spiritual dimension'--without the mind-bending assignment of the sun to house such things.
3. I think the portals on earth are likely to be much more troublesome compared to any other portals anywhere else--unless maybe, the moon.
