Kurzgesagt – In a Nutshell

What if the Moon Crashes into Earth? - Real Physics (Mostly) Today we are answering an age-old very scientific and important question: What if the moon crashes into earth? It’s more interesting and weird than you probably think. Let's start with the basics: Why isn't the Moon on its way to crash into us already? @Kurzgesagt_InaNutshell

Why We Should NOT Look For Aliens - The Dark Forest 📜Transcript

Why We Should NOT Look For Aliens - The Dark Forest The Universe is incredibly big and seems full of potential for life, with billions of habitable planets. If an advanced civilization had the technology to travel between the stars, at just 0.1% of the speed of light, It could colonize our galaxy in roughly 100 million years. Which is not that long given the billions of years the milky way has existed – so in principle any spacefaring civilization should be able to spread rapidly over huge sectors of the galaxy. And yet we see nothing, hear nothing, the universe seems empty. Devoid of others. This is the Fermi Paradox, which we have discussed in more detail in other videos. @Kurzgesagt_InaNutshell

...And We'll Do it Again 📜Transcript

...And We'll Do it Again Kurzgesagt is lying to you, in every video, even in this one. Because our videos distill very complex subjects into flashy ten minute videos and unfortunately, reality is, well, complicated. The question of how we deal with that, is central to what we do on this channel and something we think about a lot. @Kurzgesagt_InaNutshell

Is Meat REALLY Bad For The Climate? 📜Transcript

Is Meat REALLY Bad For The Climate? Food is arguably the best thing about being alive. No other bodily pleasure is enjoyed multiple times every day and never gets old. It is an expression of culture, our parents' love and a means of celebration or comfort. That’s why it hits a special nerve when we are told we should change what and how we eat to fight rapid climate change. One of the most delicious foods, meat, gets the worst press. It doesn’t help that the topic is really hard to properly research yourself and debates get emotional quickly. But clearly science can give us an answer! The reality is, well, it’s complicated. Let’s take a look at three climate arguments against meat that are used a lot and see what happens. @Kurzgesagt_InaNutshell

You Are Immune Against Every Disease 📜Transcript

You Are Immune Against Every Disease You are not a person, you are a planet, made of roughly 40 trillion cells. There is so much of you, that if your cells were human-sized, you would be as big as 20 Mount Everests. For your creepy-crawly inhabitants, this makes your body an ecosystem, rich in resources and warmth and space. A perfect place to move into and have a family. While some of these guests are welcome, most are not. Your immune system is the guardian of this planet, the force tasked with protecting yourself against the constant danger of invasion. @Kurzgesagt_InaNutshell
