Interstellar travel V: Warp drives, wormholes, and halo drives

Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments in nuclear weapons and rockets paralleled advances in space exploration, resulting in proposals for nuclear rockets. We then examined how the creation of thermonuclear weapons led to applications in fusion propulsion.
