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 […]

Light always travels at a speed of 299,792,458 meters per second. 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 […]

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 […]

Hank gets all up in your face about kissing — where does it come from, why do it we do it, and do other animals do it? From ancient India to that date you were on last night (which we won’t tell anyone about if you won’t), we explore the history of snogging and its […]

Exoplanets orbit distant stars, requiring an interstellar journey to reach them. Such a journey would take tens of thousands of years with current technology, but one group thinks they could send a high-speed probe to visit our closest exoplanet. If they’re right, we could see images of this distant world within fifty years.
