Marc V I can't address all of them but I'll have a go at one. 3) The accurately charted paths of numerous space probes which have visited all 8 planets in the solar system. I don't see where is the problem for GC! The people who plan these missions depend on the approx 66000mph velocity of the Earth in its orbit for success. If it wasn't there then such missions would all fail. Additionally, I don't think any vehicle is even capable of achieving just 66000mph let alone 66000 + 25000mph.
