At the height of the Cold War, a terrifying concept emerged: a bomb so powerful it wouldn’t need to be dropped. Known as Project Sundial, this doomsday device would have left a 400-km radius in flames and plunged the world into darkness. It was a bomb that would destroy everything – not a weapon, but an apocalypse. How close did we come to pressing the button?

For most of our history, the human population grew slowly. Until new discoveries brought us more food and made us live longer. In just a hundred years the human population quadrupled. This led to apocalyptic visions of an overcrowded earth. But the population growth rate actually peaked in the 1960s. Since then, fertility rates have crashed as countries industrialize and develop. World population is now expected to balance out at around 11 billion by the end of the century. But the big picture conceals the details.

Season 7 Episode 21 - Aired 12/22/2019
Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center. Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years. This dance is not an orderly ballet - more like a skating rink filled with drunk toddlers. This chaos makes the galaxy dangerous. Our solar neighbourhood is constantly changing, with stars moving hundreds of kilometers every second. Only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point we could encounter a star going supernova. Or a massive object passing by and showering earth with asteroids. If something like this were to happen we would likely know thousands, if not millions of years in advance. But we still couldn’t do much about it. Unless… we move our whole solar system out of the way.

A huge thanks to the experts who helped us on short notice with the video. Especially “Our World in Data”, the online publication for research and data on the world’s largest problems – and how to make progress solving them. Check out their site. It also includes a constantly updated page on the Corona Pandemic. In December 2019 the Chinese authorities notified the world that a virus was spreading through their communities. In the following months it spread to other countries, with cases doubling within days. This virus is the “Severe acute respiratory syndrome-related coronavirus 2”, that causes the disease called COVID19, and that everyone simply calls Coronavirus. What actually happens when it infects a human and what should we all do?

The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy.
