Qfwfq Posted April 18, 2006 Report Share Posted April 18, 2006 how many decimal places do you need to compute Pi to in order to be able to accurately compute the circumference of the *visible* universe to +/- 1cm?Actually, you would need to know the curvature of space over that whole region, something not currently known. If the manifold isn't exactly flat, the ratio isn't exactly pi. Quote Link to comment Share on other sites More sharing options...
IDMclean Posted April 22, 2006 Report Share Posted April 22, 2006 Nice I love to see someone actually using GR and SR for things so huge. Someday if Pi does end I'll bet it will be intimately connected to a quanta of some type. Quote Link to comment Share on other sites More sharing options...
