Non-Physical

I will apologize in advance to those of you that are well versed in physics and are about to roll your eyes at my stupidity. I am absolutely untrained in physics but frequently read articles about quantum theories and particle physics. This leads me and my small mind to ponder a few points.

1. If ones mass is altered through acceleration or proximity to a source of gravitational force, and as a result of that, the nature of time is also altered for that individual; does this also apply to particles at an atomic or sub atomic level? For example is time different for a fast moving neutrino or a particle/wave of light
2. Today we say the big bang / inflation occurred some 13.whatever billion years ago. This is a measurement taken at our current time measurement of 1 second per second per second. Given the vastly different speed, and gravitational effects possessed by different structures throughout the universe; isn't time therefore vastly different throughout the universe and therefore is the universe 13.whatever billion years old everywhere? Or is it, say 8 billion in some places and 17 in others?
3. This one is way out there. I understand that the fabric of space-time is stretched and warped by the mass and therefore gravity generated by objects. So as these objects move through space and time, the degree to which space-time is stretched or warped would vary. Is it possible that this movement of the space-time fabric could exert or generate an energy (like heat in a wire that you bend backward and forward to break it), or maybe something like a space-time 'drag' that we perceive as dark energy holding the universes matter in place. Could this energy also produce the subatomic particles that pop in and out of existence?
