    If current theory suggests the universe is destined to ripped apart by expansion and even gravitationally bound objects are pulled apart could gravity actually be sucked back into space through black holes and if so would objects thought lost to spaghettification actually become recoverable?

    The question is precipitated by a couple of threads in science forum, one speculating on the big rip, the other about an entropic future for the universe and it's effect on black holes.

    Which it doesn't.

    Also which is not predicted.

    I thought gravity is just a trick of space-time geometry. Gravity is actually the bend of space time continuum. Space-time suck space-time, I thought is should be space-time create space-time, shouldn`t it?

    No. Gravity is the inertial force that tends to cause physical things to move towards each other whereas tidal gradients are what curve spacetime. The term "bend" is improper in this context since you can "bend" a sheet of paper into a cylinder and not change the intrinsic curvature of the paper. However spacetime curvature as is intrinsic, not extrinsic

    Not even in your wildest dreams.

    This doesn't appear correct, however if evidence to contrary is presented I'm willing to be persuaded.

    It wasn't an assertion or suggestion of current prediction, it was a question calling for a speculative answer about what may or may not be possible as a result of the premise described.
