Recently, something interesting happened to me over on Google+. I uttered an opinion. Now, that in itself is not interesting, of course, because everybody does. What was interesting was that the opinion was not really an opinion at all: Earth is part of space.

With respect to Mars we talk about them as astrogeologists, astrophysicists, astrobiologists and, well, I have never heard anybody being called an astrochemist; but you get the point.
Earth is part of a wonderful, exciting universe. Earth is part of space.

And I have not even mentioned lungs yet…
