Kurzgesagt – In a Nutshell

3 Ways to Destroy the Universe The universe is going to die one day, and a fight between two titans will decide our cosmic fate. On one side of this galactic battlefield, we have all the matter in the universe; on the other side, empty space infused with dark energy. Whoever wins will kill the universe in fun ways. But who will that be? We're looking at three possible ways to destroy the universe in our newest video. @Kurzgesagt_InaNutshell

The Internet is Worse Than Ever – Now What? In 2022 nearly half of Americans expected a civil war in the next few years, one in five now believes political violence is justified. And it is not just the US but around the world. People increasingly see themselves as part of opposing teams. There are many different reasons for this, but one gets blamed a lot: social media. Social media divides us, makes us more extreme and less empathetic, it riles us up or sucks us into doom scrolling, making us stressed and depressed. It feels like we need to touch grass and escape to the real world. New research shows that we might have largely misinterpreted why this is the case. It turns out that the social media internet may uniquely undermine the way our brains work but not in the way you think. @Kurzgesagt_InaNutshell

The Last Thing To Ever Happen In The Universe The universe today is happy and healthy, with exciting things going on – but at some point the night will turn dark. Everything that once was, will peacefully sleep forever. But what is the last thing that will ever happen? Let's travel to the end of the universe… @Kurzgesagt_InaNutshell

4.5 Billion Years in 1 Hour Earth is 4.5 billion years old - which is approximately the same amount of time it took us to create this video. We’ve scaled the complete timeline of our Earth’s life into our first animated movie! Every second shows about a million years of the planet’s evolution. Hop on a musical train ride and experience how long a billion years really is. It’s the perfect background for your next party, a great way to take a break from studying, or a fascinating companion while you’re on the go … and our celebration of 10 years of kurzgesagt. @Kurzgesagt_InaNutshell

How to Win an Interstellar War Could aliens destroy us from light years away? Another day at Kurzgesagt Labs, where we answer the most important questions with science. Today: how might civilizations wage war across light years? What kind of devastating weapons could they use and what would they look like? @Kurzgesagt_InaNutshell

Ancient Life as Old as the Universe Life has existed on one planet for about 4 billion years, for all we know. But it might have started right after the Big Bang, when the universe was much stranger and more fantastic than today. A universe that might have allowed life to develop absolutely anywhere. The cosmos might be full of the seeds of life, sleeping in a dead desert, waiting for a few drops of rain to explosively bloom and grow. Tiny and not so tiny aliens might be everywhere. @Kurzgesagt_InaNutshell

Why Korea is Dying Out Every two years one million Japanese disappear, China’s population will halve by the end of the century, the median age in Italy has reached 48. All around the world birth rates are crashing – Is humanity dying out? What is going on and how bad is it? @Kurzgesagt_InaNutshell

You're a Dream of the Universe (According to Science) Absolutely everything you think about yourself and the universe could be an illusion. As far as you know, you are real and exist in a universe that was born 14 billion years ago and that gave rise to galaxies, stars, the Earth, and finally you. Except, maybe not. @Kurzgesagt_InaNutshell

How A Nuclear War Will Start - Minute by Minute Mr. President! Nuclear missiles will strike our country in 14 minutes. I know it’s your first day in office so I’m going to walk you through it, but you’re the only one who can authorize our nuclear retaliation in response and you’ve only got a few minutes to make a decision! @Kurzgesagt_InaNutshell

What Happens If You Destroy A Black Hole? Black holes can destroy everything – but can they be destroyed? What happens if we push physics to the absolute limits, maybe even break it and the universe in the process? Let’s create a tiny black hole, about the mass of our moon, in the Kurzgesagt Labs and try to rip it apart. @Kurzgesagt_InaNutshell
