Hi all, On the subject of gravity well type exhibits- does anyone out there in Museum-L land know what the correct formula for the curve is? I have seen many of them in the past and some work and some don't- my guess is that the ones that do have the right curve but I can't seem to find it anywhere- any ideas? Feel free to reply off-list if you like. Cheers from Down Under!
