[King Lear]

I'm quite interested in this subject and also connect it to the "Expanding Earth Theory" (EET)

A while ago i discussed this subject on another forum with someone who has great scientific knowledge and who is really hard working on both theories.

He said, that most planets are presumed to be gas-planets but not our earth!
But he thinks that our earth is in fact hollow and inside filled with gas, which would explain why the earth was 65 mio years ago just 1/4 of it's recent volume.

He stated this because i was guessing that the growth is increased by the neutrinos the sun sends out and the earth-core would transform it into mass (back then i saw a scientific documentary about neutrinos)

Another fine evidence: as we all know the continents fit together.
But only perfectly if the globe is 1/4 of today!
