NASA has been testing new space travel technologies throughout its entire history, but the results of its latest experiment may be the most exciting yet — if they hold up. Earlier this week at a conference in Cleveland, Ohio, scientists with NASA’s Eagleworks Laboratories in Houston, Texas, presented a paper indicating they had achieved a small amount of thrust from a container that had no traditional fuels, only microwaves, bouncing around inside it. If the results can be replicated reliably and scaled up — and that’s a big “if,” since NASA only produced them on a very small scale over a two-day period — they could ultimately result in ultra-light weight, ultra fast spacecraft that could carry humans to Mars in weeks instead of months,…

The resulting 5-minute-long video — while it focuses primarily on the travels of European and American men — offers a great look at how human migration patterns shifted along with technology, and reinforces the enduring popularity of cities as cultural destinations across time. It’s also got some surprises (guess which Southern state became…
