Oblate spheroid apparently.

I note your point over translation. I suppose it is one thing to believe that scientific discovery has to be compared with biblical teaching, but doesn't the lost in translation bit concern you if you believe the scriptures hold true? 666 and all that?

Hanging on nothing has been clarified by other people as saying you need a reference point if you say it is hanging at all. That said, if this Isaiah person is from ancient times, it wasn't a bad stab at it. Whilst trying to rationalise the Bible with known physics is folly to say the least, it was written amongst other things as trying to understand the world around us. It is the primitive instinct to fill the gaps that spoils the effect.
