This is what happens when people try to juggle two systems of measurements, confusion of a lesser, incongruent emerges. I think space exploration should only be done in miles. This way we don't make the universe appear smaller than it really is.
Yeah... with every new discovery of a new planet, or galaxy, or constellation, the world shrinks a little bit.
As the ancient did not use to say, but we do, "it's a small world." I support you. Let's not make it any smaller. Pretty soon you stretch in bed and you are pushing a galaxy with your feet five centimetres-- appardon, two inches away from your solar system.
This is what "entropy" is all about. Everything gets smaller, until so small, that there is nothing left of it. Like a Christmas cake, or a penis after sex.
