CERN + Space-Time 101

View full lesson: View part 1: View part 2: In the first two lessons of this series on space-time, we've dealt with objects moving at constant speeds, with straight world lines, in space-time. But what happens when you throw gravity into the mix? In this third and final lesson, CERN scientists Andrew Pontzen and Tom Whyntie explore what gravity means for space-time -- or rather, what space-time means for gravity. Lesson by Andrew Pontzen and Tom Whyntie, animation by Giant Animation Studios.

But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.

View full lesson: 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. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.
