Kurzgesagt takes a break from its lesssons on theoretical science to focus on something a little closer to home – the sense of feeling alone or disconnected from people, a sociological problem that’s been disturbingly on the rise as the world has modernized.
Despite our fascination with Mars, the red planet isn’t exactly the most hospitable place. Kurzgesagt looks at some of the many challenges we’d face if we ever wanted to colonize Mars. Humans can’t breathe there, it’s freezing cold, and Martian dust is poisonous.
Organic food has long been touted as a healthier and more sustainable alternative to conventionally-raised food. But are these more naturally-raised (and more expensive) fruits, veggies, and animals truly better for us and the planet? Kurzgesagt digs into the controversy.
For all of our efforts to explore space – and maybe someday colonize other planets – humans have been creating lots of space junk, which will make it harder to leave the Earth over time. Kurzgesagt explores the dangers of filling up the low Earth orbit with stuff.
From a sunny seaside vista, to a sexy sports car, to a gorgeous woman, beautiful things bring a smile to our faces. But what is it about this totally subjective and intangible concept that makes our brains react so positively? Kurzgesagt provides their take on why this happens.
Meat is delicious and packed with proteins and fats, but it’s being produced in quantities that are far greater than what nature intended. With a nod to Bob’s Burgers, Kurzgesagt explores the impact of mass-producing livestock to fill our bellies. We’re having salad for lunch.
The thought of setting up shop and living on the surface of the moon seems like a far away sci-fi dream, but we actually have the technology and smarts to do it in the next decade – assuming we had the funding. Kurzgesagt explains, in part one of their series about space colonization.
“There are more phages on Earth than every other organism combined.” Kurzgesagt takes a few minutes to educate us on the finer points of the bacteriophage, a type of virus which is constantly killing off billions of microscopic organisms all around and inside of us.
In theory, energy consumed by a black hole is trapped forever. But it turns out it might be possible to harness the rotational energy of a spinning black hole to do everything from powering civilization to creating the biggest explosive device ever. Kurzgesagt explains.
Kurzgesagt dusts off their 2013 video The History & Future of Everything and gives it a shiny coat of paint, with updated animations, and references to events of the last 5 years. Every time we hear about the Middle Ages, we feel much better about today’s problems.
Kurzgesagt explains an economic idea called egoistic altriusm. It argues that it’s in an individual’s best interest for those around him to be well off. You’ll have more people capable of solving your problems, and more people able to afford the solutions you offer.
Kurzgesagt explores string theory, and how it attempts to explain the nature of the universe. It’s supposed to solve the incompatibilities between quantum and gravitational physics by describing particles as “strings” rather than points. Yeah, we’re still confused.
There is growing evidence that giving citizens (or at least the poor) a stipend will make people healthier and happier without tanking the economy or productivity. But it can also be abused – not just by lazy or entitled individuals, but by governments and businesses as well.
It’s a nasty thought, but our bodies are teeming with billions of bacteria all of the time. At times, these microbes are helpful partners, doing things like digesting food, and at other times, they want to kill us. Kurzgesagt explores the delicate balance of the human microbiome.
Kurzgesagt simplifies two thought experiments stemming from black holes. The universe being a “hologram” is too literal though. Saying that you can describe a cube by drawing a cube is not the same as saying that a cube is indistinguishable from a drawing of a cube.
Automation has been around for centuries, but the rise of machine learning has led to new industries that need relatively few people to operate. As Kurzgesagt and many others have pointed out, this is an unsustainable trend that needs to be answered swiftly.
They sound cute and cuddly, but the white dwarfs that Kurzgesagt is talking about here will be the last bastions of light and energy in the universe as our universe eventually expires. These highly dense objects are basically the remnants of stars after they burn out.
