... Bigcrapsnip Your first error, Ralph, was to begin your entire diatribe with 'I assume...'. Your second was to refer to 'looking down on the solar system' without defining your frame of reference. There is no 'down'. At this point I lost interest. That's a bit of a low blow IMVHO. There's a general convention (that annoys the pants off antipodeans (a term which is itself based on a general assumption about which way is "up") about which way is "up") which is that North is up. True, there is no "up" in space, but in a vernacular sense most people would consider looking "down" on the solar system to indicate looking at the ecliptic plane in plan view from a vantage point above one pole of the sun, approximately, that pole being the one that points in the approximate same direction as the North pole of the Earth. That being for purely conventional reasons, because earth maps, by arbitrary convention, generally have North at the top. He's not drawing some detailed conclusion from this choice of reference frame (as he would be say in a discussion on SR), he's just setting the scene. If, for instance, one said "looking down on America, one can see the Grand Canyon" one doesn't need to specify precisely where in space one is. A reasonable reader can easily understand what the writer means. Read more widely, and be more critical of others assertions, value evidence more than opinion, learn mathematics. These things will improve your ability to reject crap. Best wishes, -- DT Replace nospam with the antithesis of hills ******************************************* Valleys? Holes? Pits? Plains?
