Something seems incorrect with their volume calculations to me.
Well...it is admittedly an "estimate"....would it make you happier if the sphere that encompassed all of the water on Earth were.....1,000 miles in
diameter, instead of only 860 miles??
Or, let's make it 2,000 miles in diameter!! How's that?!? Still, compare it to the Earth, in size and distribution.
WHAT this thread (and the visuals, and the maths) show is:
WATER, whilst one of the most abundant properties of the Universe, still pales in comparison to MASS of the rest....though, we need the stuff ("we",
being the only known biological life-forms).
Oh, and......using this mental visualization of the "TOTAL" water on this planet, we can think a lot about....well, "HOW" it got here....the primary
thesis on "how" is not only the existing H2O as the planet cooled, after formation....but other
extraterrestrial "imports" of water, early in
our planet's history.
THIS is big, when it comes, sometime in the future, to our potential to "terraform" other planets. Should we wish to embark on such
