Poor English grammar aside, this person seems to subscribe to the theory that the Sun "ejects" all of the planets. They believe that the planets weren't precipitants of an accretion disk in the early phases of our solar system's formation, but that the sun periodically burps out planets, and Mercury was the sun's most recent "burp". Obviously, such a theory is completely rejected by mainstream science. No one understands this level of science because it's not science at all. One thing though, they do seem to be somewhat correct in their account of the solar magnetic dynamo. The tachocline, the boundary between the sun's solid core and it's liquid mantle, is thought to be largely responsible for driving the 11 year solar cycle. But does the core have a 70 km radius? No.
You're welcome. :) I used to cruise the phys.org forums when I was interning (they didn't give me enough work yet), so I'm no stranger to crack pot theories.
As an aside I used to read a lot of crack pot theories about The Nibiru Cataclysm which basically is that this mysterious planet is the reason everything in orbit (look at the solar system actually) has an egg shape. The theory being that "Nibiru" is out there and it (should have, following these theories) passed by in 2012, I wonder if the Aztecs were the reason we have so many 2012 predictions (that fell through)...
I wanted to believe in McKenna's Timewave Zero pitch, but then I grew up.
