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.
