We've all had geek debates before — is Superman faster than the Flash? Is Picard a better captain than Kirk? Are fast zombies scarier than slow ones? A panel at this year's Comic-Con took on one of the more controversial of these subjects, by debating just which fictional spaceship is indeed the best. But it turns out that a member of the audience had maybe the most convincing argument of all — and it was none other than Dr. Neil deGrasse Tyson. He explained that the measure of a starship's worth isn't in how it looks today, but how it was seen by people when it originally came out. Measured by this metric, he believes that the USS Enterprise from the original Star Trek TV series is the best spaceship of all time, which Tyson goes on to describe as "astonishing, awesome, beautiful, and seductive." We tend to agree.
