How small of balls are you thinking? I remember(I think it was on Bill Nye the Science Guy) someone did that and they had to use the whole town.

As long as you ignore the sun, I think it's possible to do it with balls... http://230nsc1.phy-astr.gsu.edu/hbase/solar/sizes.html#c3 They do it here, using a bowling ball sized object as the sun and scaling everything to that.. http://www.noao.edu/education/peppercorn/pcmain.html Link to comment Share on other sites More sharing options...
