Relativity black holes singularities and problems with infinity?

ok, cool that your doing this stuff. But is clear to me that you need to use newer equations than newtons. His was remodified years ago to include relativity. And all the one dimensional stuff looks at things from an incomplete perspective. Learn some vector calculus and learn how physics has been dealing with infinity all along. Like did you know that physicists consider an electron merely a point charge, aka a point in space with a volume of zero but still a charge density? How is that possible?
