- All right, cool. Ooh, it's on. (chuckles) Amazing. (says good day in German), Texas. (Sonja and audience say good day in German) I'd let to set the mood with a short clip, if that's all right. There should be some sound now. - [Voiceover] Mayday, Mayday.

Hello, can you hear us? Can you hear us? Can you-- Okay, over. I mean, we are sinking! We are sink-- - Hello. This is the German Coast Guard. - [Voiceover] We are sinking! We're sinking! - What are you thinking about? - Well I hope that sets the mood. Well, hello and (laughs) thank you for joining me here today.

This is the room where we save the world. My plan was to bring a towel just in case something goes wrong. My god, when I asked people yesterday, nobody seemed to get a reference of "The Hitchhiker's Guide to the Galaxy. " So how many people actually read the book? So a few, okay.

Well I left my towel at home, so let's just hope for the best. So what is world? World is a common term for everything that goes on here on planet Earth: human civilization, life, all of our history, the world as we know it. From a more philosophical point of view, world may also refer to the temporary existence of mankind, our nature of becoming and being, reality, all the things that happen to be meaningfully relevant to us, the so-called ontological universe, the world we live in.

So on this slide, shows a picture of the world, more precisely planet Earth as seen by the Apollo 17 spacecraft crew on their way to the moon on December 7 in 1972. The Blue Marble as it's called is the first image that captured the entire globe in one single frame, and it became the most iconic and widely spread image in human history, a symbol of globalism, humanity, and furthermore modern environmental activism.

So seeing Earth from this perspective, this tiny, fragile ball of life hanging in the dark vastness of space, a rather hostile environment and solarly protected by a thin layer, which we call our atmosphere. You can't help but feel comfortless awe. Many astronauts report a profound shift in awareness while viewing Earth from orbit.

National boundaries seemed to vanish. Conflicts between people seem obsolete. The fragility of natural systems becomes apparent, a phenomenon that is also known as the overview effect. And it describes the prompt understanding that we're all in this together, and it should create a sense of agency to care of this environment.

However, it's kind of hard to get an overview from down here, right. So earlier in September, I had an incredible opportunity to attend a thing called HATCH, which is a four-day annual retreat in the mountains of Big Sky in Montana. You're supposed to bring bear spray.

That was a first. And it's for a bunch of creative types. It was a stellar mix of solid inspiration and hot tubs, and I'm just gonna leave it at that. One of the brilliant individuals that I met there was Michelle Thaller, who's an astronomer at NASA. And here's a pro tip.

If you ever meet an astronomer, don't miss the chance to have a chat. That's Michelle. And I would like to tell you a story that she shared at HATCH. Maybe you remember it the next time you stand under a clear night sky. So a star is not more or less than a cloud of dust, collapsing under force of gravity.

This compressed space, the body of a star, is the birthplace of every element on our periodic table: oxygen, nitrogen, carbon, et cetera. So when the core of a star collapses completely, it's the most violent act in the universe: a supernova explosion, the death of a star.

And it's also the only instant where iron is created. Now does anybody wanna have a guess where the bright red color of the blood in our veins comes from? Iron, exactly. - [Voiceover] Iron. - [Sonja] So in conclusion, we're dead stars looking back up at the sky.

We're the bloody universe. And if an astronomer tells you that, you better believe it. So that should make (laughs) feel us pretty good about ourselves, I guess. And I'm hoping we can keep the spirits up for another 20 minutes while I'm trying to get the bottom of this runtime error.

There will be time for questions. And while this seems maybe like an excellent opportunity to do a live coding session, trust me, that would end in disaster and be complete madness. Instead I'd like to start with a life saving session, ooh. (chuckles) And it too starts in a terminal, more precisely, Terminal A at Tegel Airport in Berlin.

That's where I live at the moment. Berlin is 5,582 miles and a few very confusing timezones away from San Antonio. Equally confusing are the varying calculations of the amount of CO2 that long-haul air travel carries with it. My personal share in this regard apparently comes up to more or less one ton, which matches the weight of 10 baby elephants.
