Yep I'm saying that pretty much the entire globe would be covered over with water that then receded as the planet grew. Is it really that hard to imagine? I mean most of the planet is already covered by water.. with less space for the water it has to go onto land, and honestly it would not take a lot of lost space to flood over the continents. And back then there was a lot less ICE at the poles. As we all know currently the big thing with global warming is that the poles will melt and that water would flood over huge sections of land. And thats just a small part melting. With it all melted and the earth smaller.. yea the planet would be 95-100% covered by water.
And as for the tectonics.. this is what tectonics is. Earth broke up into continents as the planet expanded. These continents are still free floating on magma after breaking apart from a much larger chunk (the gaps being fill in by magma to create "new" earth. Just because the continents broke up from a different mass in this theory than from the other theory doesn't make it not tectonics.
Examples of expansion and contraction? k.. well the video gave the example of mars. That giant rift across the center doesn't come out of nowhere. The planet saturn is "squashed" into an oval shape and stretched out due to the speed of its spin. As that speed changes over the span of time the planets shape will change. Some of the moons like Europa are changing shape all the time as they are tugged by their parent planet's gravity, slightly stretching them and causing the planets to expand slightly toward the planet.
I'd give more but.. honestly.. do i have to? Things contract and expand all the time. Just because something is the size of a planet doesn't mean that it isn't subject to the same laws.
Earth is an extremely dynamic planet. There's the liquid magma that is churning and spinning under an extremely thin layer of crust. There's the moon tugging and spinning around the planet. All of that magma wants to bust its way through to the surface. Oceans flowing over the planet giant continents floating around.. etc etc.
If the first real theories coming out to explain our planet are incomplete or slightly off its understandable. We're getting new knowledge every day about or planet that will lead to these theories changing. 60 years ago there weren't satellites mapping the world mile by mile over land and under sea and ice to show what was what. The new knowledge may be pointing to our planet expanding. If they are they are, you can only take the sum of knowledge and form your own theories.
