Explore what would happen if all of humanity’s satellites disappeared and the real-life scenarios that could lead to such a catastrophe.

Uploaded 02-02-21

--

What would happen if one day all of humanity’s artificial satellites suddenly disappeared? Within hours, most of the planet’s traffic would grind to a halt, the world economy would shut down, and most countries would declare a state of emergency. Even in the best-case scenario, our civilization would be set back by decades. So, what are the odds of this actually happening? Moriba Jah investigates.

It’s 1819. The US is preparing to make Missouri and Maine new states. One representative insists that slavery shouldn’t be allowed in any new state. Another believes it should be a state’s right to choose. A compromise is proposed: slavery will be allowed in Missouri and prohibited in Maine. Can you spot the problem with this compromise? Elizabeth Cox explores the middle ground fallacy.

Journalist Mustafa Akyol talks about the way that some local cultural practices (such as wearing a headscarf) have become linked, in the popular mind, to the articles of faith of Islam. Has the world's general idea of the Islamic faith focused too much on tradition, and not enough on core beliefs? (Filmed at TEDxWarwick.)

Dig into the science of enhanced rock weathering, a technology which takes carbon dioxide out of the air and stores it in rocks.

--

Mount Teide is one of the world’s largest active volcanoes, and there may be a way to use the basalt rock inside it to save humanity. Obviously, destroying an ancient volcano would cause catastrophic and unpredictable ecological fallout. But what if we harvested only some of that basalt— could it really stop climate change? Elise Cutts explores the fascinating science of enhanced rock weathering.

Lesson by Elise Cutts, directed by Ivana Volda.

Your hands, up close, are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you. But there are two extraordinarily simple ways you can keep that from happening: soap and water, and hand sanitizer. So which is better? Alex Rosenthal and Pall Thordarson investigate.

Explore the classic poem, “Beowulf,” which follows a heroic prince as he fights to free a kingdom from the monster Grendel.

--

An epic written in Old English, “Beowulf” is known for its haunting monsters, dream-like language, and paranoid perspective, where violent threats are always waiting on the fringes of society. The action follows Beowulf, a prince of Geats, who travels to aid a kingdom in freeing itself from a monster’s reign of terror. Why is this poem considered a classic? Iseult Gillespie traces the hero’s tale.
