How large is the smallest piece of DNA compared to a hydrogen atom? What chemical elements go into the average strand of DNA? If the human body is mostly H2O, then why are we considered "carbon-based" lifeforms?

I'm confused. How is the gravity of any other universal object even comprable to the intense gravity of a black hole? Also, from what I've studied, once matter falls past the event horizon and into the singularity, gravity becomes so intense that no known form of energy can escape.

As I understand it, electrons orbit a nucleus in a sort of spherical "cloud", kept in tow by said nucleus' protons. However, when two or more atoms combine, what keeps the negative charge in the electron "clouds" from simply pushing them apart?
