“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.
“Imagine it like setting a sea of gasoline the size of the universe on fire.” Kurzgesagt sums up vacuum decay, a theoretical catastrophe that would wipe out the universe at the speed of light and reconfigure it into a state where life as we know it would be impossible.
Kurzgesagt takes a look at what seems like science fiction, but could quite possibly revolutionize the world. With the ability to manipulate genes, we could create just about anything we want, from made to order babies, to better foods, to the fountain of youth.
