TED-Ed: Can you solve the dark matter fuel riddle? - Daniel Finkel

An ancient, abandoned alien space station has been discovered. Can you beat everyone in the galaxy and reach it first? -- It’s an incredible discovery: an abandoned alien space station filled with precursor technology. Now every species in the galaxy is in a mad dash to get there first, but you’ve got a problem. Your ship can’t hold enough fuel to get you there unless you vent caches of it into space at precise points and then come back for the fuel later. Can you reach the alien space station? Dan Finkel shows how. Lesson by Daniel Finkel, directed by Artrake Studio.
