This seems to be an exaggeration though to say that we basically have the technology. We have the ability to build a ship that would survive 300,000 one megaton nuclear explosions for 200 years, for a reasonable amount of money? What if this paper spacecraft is actually beyond the realm of material science?
- adrianN 6y agoI read a book about the topic. The conclusion seems to be that it was doable with 1960s tech, but the test ban treaty, concerns about fallout and the ban of putting nukes into space killed the project before it could produce a prototype.
- jandrese 6y agoWhich only makes sense if you ignore all of the details. In 2020 we still don't have any proof of concepts for a self-sustaining biosphere that includes people, much less a spacecraft that can survive for hundreds of years without major maintenance. We don't even have a good solution for absorbing all of those hard gammas from detonating 300,000 fusion bombs in close proximity to the people.
- adrianN 6y agoThe ship itself offers protection from the radiation. The pusher plate, all those bombs, that's quite a bit of shielding. The life system is of course a problem, but that doesn't change the fact that the ship would be pretty fast.
