There Are Thousands of Alien Empires in The Milky Way

See the news from a bird's eye view above the framing at ground.news/nutshell

An assumption often made is that spacefaring civilisations will be after planets, rather than resources for habitable megastructures and fleets

Statistically speaking, no matter how good Fermi is at approximating things, we're still externalizing from an observation on a sample of N=1.

To extend the analogy - knowing what happened when other civilisations discovered the Polynesians suddenly makes the idea of us meeting with aliens pretty scary

I feel like for interstellar communication or interaction between civilizations. You need to have one of three things: 1) Travel speeds above light speed 2) Wormholes 3) a species which ages very slowly. If their life expectancy is 2000 years, traveling for some hundred years is still feasible

There's one complication: we don't actually need to live on planets. With the high tech that allows interstellar travel, you can easily build giant space stations to live on, powered by your friendly neighbourhood fusion reactor (your Sun) even if you yourself haven't figured out fusion.

7:35 Flirted with extinction might be one of my top kurzgesagt phrases

I believe that colonizing planets by any alien is just extremely hard and practically impossible. For example, the nearest planet outside our solar system (Proxima Centauri b) is about 4.2 light years away from us. And right now, our fastest space craft is about 1/1675 the speed of light. That means that we would have to build a space ship that could fully sustain human life for 7035 years while not running out of power to even reach Proxima Centauri, which most likely could not even support human life. And that is THE CLOSEST plant.

Man every time i watch your videos i always wonder how much it took for you guys to finish a single frame. Steller animation guys. Keep up the good work

I just want to say, analogizing Oceania to space is brilliant

I was not ready for "its free real estate" to show up in a Kurzgesagt video of all places

Large distances in space become a non-problem once wormhole routes are established

the divergent evolution of different planets is something i felt was really missing in dune, that i really wanted to see more of

"And this, is a hypothesis surrounding aliens" "Kurzgesagt, this is the ninth time you've shown aliens in class today"

I really want a Civilization-style video game with Kurzgesagt's art style where I can colonize or conquer space.

You guys at kurzgesagt are so awesome at making things simple to learn and grasp. Keep up the great work ❤

Animations are great and you guys can talk about any topic objectively. Really good.

"Mars is the worst,.... except Venus is even worse" I giggled at that for some reason😂

Just for the fun of it, I have translated every single space letter into our alphabet based on how they are shown in each topic's title. So here's what every single timestamp of the video says: 0:49 - Teddy. Daniela. Mari. Yvo. Asteroids!!!! 2:56 - C-A-S galaxy Simba Nala Mufasa Salem Group Mrs. Norris System Cheshire Cluster Tom ?i?i Cluster [Could be Jiji, Qiqi or Zizi. These 3 letters were never presented in their space form] Crookshanks Cluster Garfield Group Meowyh Star 8:24 - Send donuts! 8:33 - The Great Frog Of Frogisland 8:37 - Lunch Date at ? PM Today [Could be any number] Don't forget! Vessel Approaching! 8:58 - How dare you!!! 9:04 - Easter System

The idea of this video is amazing; it's a fabulous example of free association coming up with new ideas.
