I watched this recently and wondered what any monitoring Starfleet outposts must have thought about the situation. How far out did the causality loop expand? Did it end around the vicinity of the Enterprise after it was thrown back? We know that time continued on outside of the loop, hence the sixteen/seventeen days that were lost. Shouldn't Admiral Necheyev have sent Picard a jingle to tell him to quit stalling and get to his next assignment? Edit: Surely the combined matter/antimatter explosions of the Enterprise and Bozeman colliding should have alerted Starfleet sensors that something was amiss. Especially FOUR matter/antimatter explosions in the same area of space in under three weeks.
