"If you think about teleportation. An item being one place, and then another. What happens to the linear time-space model?
"Or what about objects that are in several places at once?"
There is no such thing as teleportation, or things that exist in multiple places at once.
Regarding the universe being created over and over, that would require that the universe be destroyed each time, and that isn't happening. That being said, there may be multiple universes, and I am incompetent to say there is or isn't.
There are claims of quantum teleportation, but that only involves information, not mass or energy, which doesn't violate the speed of light. The warping of spacetime is information, at least in part, and doesn't require time to effect. As mass moves spacetime warps without delay across the full extent of the universe. Gravity is instant, not taking time to travel like forces/mass, because the shape of spacetime doesn't have to travel to spacetime to change it's shape. It is everywhere spacetime is. It doesn't have to go there.
