930 years ago, there were Vikings. Can you imagine one of their ships showing up today? How plausible is the Discovery in 3190?
Why don’t you go on all our important missions. We lost all our muscle strength in 1900, so we can’t row that fast. Forget our carriers and subs, wait until our enemies get a look at your axes and war hammers! We’ll just upgrade your ancient ship with electronics and nuclear reactors, that should be easy enough. And I’m sure you have a lot to teach us about military tactics, diplomacy, education, etc. We’ve not done much for the past millennium. You’ve been to America before; can you talk to them for us? We just can’t get anything done without you Vikings.
