I calculated the distances of the nine planets from the sun by one of 21 formulas that I used to define the causes of gravity. I also adjusted the orbital velocities. The differences from the standard velocities are small (from less than 1m to less than 46m).

Too bad. If you had used a regression not only would the value more likely be unbiased, but you could drag out a confidence interval on either G or M or both. More generally, if you drop the requirement that M be constant you might even get a ballpark on the local DM distribution. -- [Summer's] our accident season. It's when people get stranded. They break wheel nuts, blow tyres. We had a chap in here two days ago, he'd blown four tyres on his vehicle driving around in these temperatures. You can imagine if it's 49C in the shade, we're talking 77, 78, 80 degrees out in the sun. I mean, you're running rubber on [the road] -- tyres just can't cope with that sort of condition. -- Phil Turner, Manager Maree Hotel, 2 Jan 2014
