Okay, those that know more, feel free to jump in here. For dissolved hydrogen to be the source of the extra volume, that would mean the Earth was always around 1 Earth Mass, right?

It's not getting many more matter, it's just converting the matter it has to a less dense version. So wouldn't that also require a LOT more energy to push the surface out that far against the same gravity we have now?
