I've read that at the center of large celestial bodies there's zero gravity (or close to). While confirmation would be nice, if true, I'm wondering how large that area can actually be and moreover, does it scale up with more mass and/or even size - that is, does the sun have a larger center area of low (zero?) gravity than the earth and so on with evermore mass. Or is that area the same regardless of mass' size?

Thank you

Excellent point, well made!

So if the original poster wanted to have a 10km sphere in the center of the earth of zero gravity (earth gravity at least), then all they have to do is hollow out 10km and they are good to go?
