Sun, Moon and stars

Really, David, you mustn't believe everything you read on the internet!
On the other hand, it's perfectly acceptable to believe everything you read in books, as there have been books for hundreds of years.
Which inspires me to answer your question about how the moon stays in the sky. I have been reading Tom Weller's classic text, Science made stupid. This is what he had to say regarding celestial mechanics:
"The moon can't fall down because it is in orbit. An orbit is the interaction of a combination of forces - such as gravity, inertia, centrifugal force and others - that result in a perfect balance."
Recently, it has been pointed out that gravity, like evolution, is only a theory. I think Weller was aware of this because he continues:
"Nevertheless, it is a good idea to stay indoors as much as possible."
Hmm. I've been thinking about the layout of this website. I know I promised myself - as well as the court system - I'd never go back to computing. Still, I notice that in a blog, the posts run most recent first, and then back in time down the page. That it makes it rather difficult to follow the thread. I suppose the reader could turn their computer upside down, but then bits might fall off and the letters will also be upside down. An alternative might be to reverse the passage of time, so that the posts appear in the opposite order. I'm not sure if this is possible, however - I can find nothing on it in Tom Weller's book.
Or maybe I could just try smearing Oil of Olay on the computer screen. No, that didn't work either. (Although the appearance of wrinkles and fine lines has been somewhat reduced.)
