Well a fairly brief search turns up these first few: http://www.sciforums.com/threads/no...g-at-an-accelerated-rate.158122/#post-3412310 http://www.sciforums.com/threads/is-there-anything-faster-than-light.155933/page-4#post-3374691 (yes even danshawen got it right here and there) http://www.sciforums.com/threads/cosmological-red-shift.155893/page-9#post-3373463 (ditto) http://www.sciforums.com/threads/gravitational-time-dilation.145889/page-13#post-3298347 (the best of this bunch) http://www.sciforums.com/threads/wh...-doesnt-make-sense.144835/page-9#post-3284862 I'm not picking on you exchemist re that particular matter - it's no sin to forget when the last 'refresh' was some time ago. What really irritates is to have put in a lot of effort correcting what will remain unnamed folks who then quickly return to repeating the original error again and again - sometimes in the same thread let alone subsequent ones. All too prevalent at SF. A not-so-merry-go-round from my pov. But those that treat the place as a carnival would likely disagree.Please Register or Log in to view the hidden image!
