Response to Matthew Miller re Geocentrism
... R. Sungenis: Not so, since geometry and dimensions would be the same. Miller: We'd See Differently, if we Were Here at all None of that really matters as we'd probably be bathed in lethal radiation. A sun small enough to be kept in Earth orbit yet bright enough to produce as much light as the one we ...
