I don't have clue as to the what or why of gravity or any idea how it can change the flow of time You probably remember the history of Newton vs Leibniz. Leibniz said, "fine, Newton, that's how gravity works, but what IS it?" The argument continues today. Neal Stephenson does an entertaining job of delving into this whole period in his trilogy.

why protons all positively charged stick close together The answer is elementary, my dear Watson. GLUONS. Gluons (glue and the suffix -on) are elementary particles that cause quarks to interact, and are indirectly responsible for the binding of protons and neutrons together in atomic nuclei. In technical terms, they are vector gauge bosons that mediate strong color charge interactions of quarks in quantum chromodynamics (QCD). Unlike the neutral photon of quantum electrodynamics (QED), gluons themselves participate in strong interactions. The gluon has the ability to do this as it carries the color charge and so interacts with itself, making QCD significantly harder to analyze than QED. en.wikipedia.org
