Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. Space-time is a pretty confounding subject to wrap one’s head around, though, so we asked CERN scientists (and all-around super nerds) Andrew Pontzen and Tom Whyntie to break it down for us. Below, the full three-part series, complete with black holes, space-time diagrams and a load of wibbly-wobbly timey-wimey stuff.

The brilliance of bioluminescence: A TED-Ed Lesson and TED Talk pairing


Did you know that there are animals that can actually create their own light? You’ve probably noticed this bioluminescence in the fireflies that might light up a park on a summer night. But there are also a lot of glowing fish and other sea creatures that hang out in the deepest, darkest depths of the ocean that use their luminous powers for survival, hunting and mating.

In this roundup, we’ll take a look TED-Ed’s best bug lessons, from the icky to the inspiring to the totally insane.

Turtle bites, solar energy and 400 hours of crochet: A very unique TED-Ed Lesson


Every once in a while, a TED-Ed Lesson is animated in a way that leaves the audience asking, ‘How in the world did they do that?’ The Why aren’t we using solar power? lesson, written by Alexandros George Charalambides and animated by Ace and Son Moving Picture Company, is one such example. We sat down with Animation Director Richard O’Connor to untangle the labor intensive effort that went into this lesson on solar energy.
