Time is not real, it's a result of limited/ mortal consciousness experiencing the healthy accumulation or deterioration of molecular structures.
Can you build a machine that rearranges molecules from spacetime x to z?
If you somehow could fuel this machine with God (cause that's the kind of energy requirements were talking about), you would be God.
These are my five cents, timetravel =! Feasible.
Maybe in the future when we have integrated science with quantum physics, in all aspects.
