thedarkshade Posted November 18, 2007 Share Posted November 18, 2007 But then there's Newtons Third Law. If the earth is rotating around you, you must be falling towards it at the same rate that it falls towards you... Theoretically yeah! Link to comment Share on other sites More sharing options...
MrMongoose Posted November 18, 2007 Share Posted November 18, 2007 Isn't theory all that matters? (other than custard) Link to comment Share on other sites More sharing options...
thedarkshade Posted November 18, 2007 Share Posted November 18, 2007 Isn't theory all that matters? (other than custard) I think reality matter more, because we live on it! We now have theories and models about time travel and wormholes too, but how possible are they??? Link to comment Share on other sites More sharing options...
MrMongoose Posted November 18, 2007 Share Posted November 18, 2007 Well in reality an observer (say you) and another object (say earth) orbit around thier combined centre of mass, which if we take a reference frame rotating such that the relative angle of the line of centres of the two masses is constant in the reference frame, then they just stay a constant distance apart and theres no reason to assume there is a force acting on either. But then when you consider the fact that a third object (the sun) is orbitting us, both our observer-earth system and the sun must be accelerating towards each other to maintain an elliptical orbit. So whilst the first of my two paragraphs is entirely theoretical (and wrong), the second paragraph shows the truth by drawing from reality Link to comment Share on other sites More sharing options...

MrMongoose Posted November 19, 2007 Share Posted November 19, 2007 Theory that has a strong correlation with repeatable empirical measurements matters until similar measurements disagree with the theory. Link to comment Share on other sites More sharing options...

JaKiri Posted December 1, 2007 Share Posted December 1, 2007 Yet another hit and run thread by BSG CORP, from one science forum to the next. At least he's saying stuff that's by and large true, rather than posting gibberish then running away. Link to comment Share on other sites More sharing options...
