From birth, mammals rely on milk for nutrition. We’ve been taught for decades that drinking cow’s milk is good for us, and part of a nutritious day. But as Kurzgesagt explains, recent studies call into question whether milk is really good for us, or if it’s slowly killing us. Plus, its production has dire environmental consequences.
THE BEST Kurzgesagt
If you follow them on any regular basis, you know that Kurzgesagt is mostly focused on videos about science, the future, and the nature of our universe. But this time, they offer up a clip that is more about improving our lives in the here and now, looking at how gratitude works, and why it’s so important for us to embrace it.
Sending cargo and ships into space is extremely expensive and resource-intensive. But there’s an idea that’s been bandied about that would use endlessly-moving tethers to catapult ships into space from Earth’s orbit. Kurzgesagt explains how this relatively simple concept could dramatically improve space travel.
If you find space science fascinating, check out this clip from Kurzgesagt, in which they explain how neutron stars work. These phenomena may only be a few kilometers in diameter, but have an insanely dense atomic nucleus and powerful gravity, thanks to their origins as massive stars which have collapsed and gone supernova.
It’s a terrifying thought, but in the interest of keeping us educated about the dangers of nuclear weapons, Kurzgesagt is here to teach us just how awful it would be if humans ever were ever to detonate a nuclear weapon in a city. Even worse, we actually did this to people back in WWII.
“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.
Kurzgesagt already taught us how ants thrive on war. But it turns out that one particular ant species has used their fighting and strategic skills (with a little help from humans) to build a truly global empire. We wouldn’t doubt if their numbers were actually in the trillions.
For as much as we think of our planet as good old terra firma, there is so much more to be seen and explored at the beneath the surface of our oceans. Kurzgesagt takes us on a deep sea journey to learn about some of the many species that dwell in the darkest waters.
Think that humans fight and kill a lot? Kurzgesagt aims its magnifying glass at the tiny world of ant colonies, where billions of the bugs violently battle against other kinds of ants and insects every single day of their lives. From decapitations to cannibalism, life as an ant can be brutal.
There’s been a long-held concern that the electromagnetic radiation that emanate from cell phones, power lines, and other devices could cause harm to our bodies. But is there any truth to this concern? Kurzgesagt attempts to separate the fact from fiction in this controvertial topic.
You might think that mammals always ate meat, but it turns out it was an evolutionary necessity due to changes in Earth’s climate. Kurzgesagt explores whether or not this change in our diets was actually good for us, or if eating meat truly has a negative impact on our health.
Kurzgesagt takes on one of the most bizarre and terrifying objects in the universe: neutron stars. Formed when certain giant stars collapse, neutron stars are made of strange matter, which are theoretically “perfectly stable.” And that’s where Physics and English disagree.
Another day, another happy thought about the end of the world from the guys at Kurzgesagt, as they asked scientists to put on their thinking caps about what might happen if we gathered up the approximately 15,000 known nuclear bombs and blew them all up at once.
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.
