nucleus is extremely fluffy by general relativity standards . for black holes the mass and size are linearly proportional . the solar mass black hole has few mile size and has density few times smaller than that of the nucleus . solar mass is about 10^57 protons or about 10^55 heavy nuclea like uranium . so in order for general relativity to be important for uranium nucleus, it has to have a size of 5 miles/10^55 or about 10^-49 cm . instead heavy nuclea have a size of about 10^-15 cm . so nuclea are 34 orders of magnitude fluffier than they should be for any general relativity to be of any relevance . they are as good as grain of salt
