Interstellar Challenges - Gigapower sources, automation & space medicine

Challenges with Interstellar Travel – Giga-power sources, automation, and space medicine. In this episode, as a layman I explore a few still-valid and major hurdles that prevent us from moving forward with plans to travel to other star systems. Those of inadequate power sources, weak and far-behind automated or highly-autonomous systems, and our lack of ultra-advanced space medicine systems. An effective energy source, for interstellar-scale ship construction and to actually power the ship, still evades us. We hardly can provide energy for all of us here on earth, let alone our ability to balloon our energy production and take that energy to outer space. Our automated systems may be amazing to us laypeople. But a deeper look at them render them as rare, incapable of much, and extremely fragile and unreliable. Our computers are error prone, and human intervention is needed for the most rare and advanced systems in a few places on earth. So, the widespread availability of these system and the robust reliability, necessary for an interstellar program, seems to be far far away. Lastly, space medicine, although we laypeople see it as advanced, in reality is not that different from what we see here on earth. In reality, I believe it is much less advanced that earth based medicine. For example, he can hardly perform simple surgery in space, let alone think that we can replace organs there. And, human birth, which must be a non-issue for long duration space flight, has been little talked about in the context of space travel. Let alone hoping to carry human births in space any time soon. In short, these 3 major areas present more than daunting challenges to crewed interstellar travel, these and other hurdles utterly prevent it.
