Bigbang Bigcrunch Singular event?

    Bigbang Bigcrunch "Singular" event?

    Ok so im just a layman that reads too much and understands too little, but I was hoping someone could help me out with this. Ive read alot about the theories of open, closed, flat universe etc. Some theories say the universe expands to infinite size after infinite time, some say there would be a point where gravity would halt expansion and end (or begin) in a big crunch, my question is since this universe either is born or dies, or both in a "singularity" is this not a singular event? What I mean is if the universe had no moments (space time geometry) or infinite space time curvature no so called "before" the big bang and so no matter how far the universe expands and time passes, all such propogation back along an x,y,z reach that non event then isn't time the same? Is the expansion of space time to infinite size after infinite time just as paradoxical as an infinite space time curvature singulatity where spacetime is confined infinitely? Is spacetime expanding in an attempt to reach an impossible zero space time curvature equaly as impossible as the infinite space time curvature of a singularity? Also since from any frame of reference the rest of the iniverse seems to be receding from us couldn't one say that that the big bang singularity actually intersects all points in space time and that is exactly what you should see? If time is relative and gravity slows the passage of time like say inside the event horizon of a singularity then all events outside would seem to be happening faster the further away from that singularity to the observer inside. Then isn't the expansion boundry of the universe (if there is one) a perception of the shift in the event horizon of the big bang singularity itself?
    Another question if mass of the universe is getting smaller because of E=mc² stars pumping out photons which follow the curvature of space time but don't nesseccerily participate in gravitation then couldn't one say that the big bang singularity is evaporating mass and losing space time curvature or "expanding over time"?

    So to recap does anyone think that the Bigbang singularity appears to be inflating to infinite size after infinite time and zero space time curvature in one direction (which it can never reach) and contracting to zero size with zero time and infinite space time curvature in the other direction? It's worth mentioning that both events when you have a good think about them are equally implausible but not illogical. So Could one theorise that there is a "singular" singularity called the Bigbangcrunch?
