I am not sure of this but i was just wondering if it is possible. If a person is pulled past the event horizon of a black hole, the differences of the gravitational pull on opposite ends of the person is so great that the person would be pulled to look like "spaghetti." However what about the individual atoms that make up that person? Wouldn't gravity have a different effect on different parts of the atom? Gravity would pull certain electrons more than others, and therefore essentially pull the atom apart. If this is true than wouldn't a black hole have a different effect on more complex atoms, such as a helium atom being effected in a different way than an atom of iron?
