Question:
Instead of turning around at the halfway point and using the same thrust to decelerate, would it be possible to, theoretically, initiate an explosion in front of the craft, equal in yield to the amount of thrust used to achieve whatever speed your craft is at when you need to start accelerating? Kind of like the old police trick of pulling in front of a speeding car and using the police cruiser to slow it (but with a BOOM instead of brakes, obviously).
Only if you want everyone squashed to a jelly. The point behind the continuous acceleration, flip, and continuous deceleration is to provide a 1G environment so that the passengers/crew experience Earth normal gravity. Coasting along and slowing down with an explosion means years in a zero G environment followed by a gargantuan deceleration. Whatever bones remained within the passengers and crew would be snapped like twigs.
