If the Earth radius has increased 4-fold, the volume has increased 50-fold, that suggests the planet is hollow.
This model for how seismic waves from Earthquakes spread, that they loose energy with distance, then converge at other side of Earth, 180°, on a globular hollow planet with a lithosphere crust, with a "shadow zone" between around 104° and 140°, fits perfectly with the data.
This is Titan in infrared at 5 micron taken in 2009[1], could this be a polar hole, on a hollow Titan, and the thick atmosphere of Titan reflecting light on those wavelengths from the internal "sun" (a plasmoid) just like you clearly see the atmosphere of Titan does around the rest of the moon as those wavelengths are reflected from our sun?
The x-rays emitting from Jupiter's poles that CHANDRA discovered two decades ago[2], could they be signatures of polar holes on Jupiter, a hollow gas giant?
