Carl Sagan's narration of the Pale Blue Dot passage, reflecting on the Voyager photograph of Earth as a tiny speck in space. It is a short meditation on humanity's smallness and shared home.

HN commenters return to it for perspective, comfort and Sagan's soothing voice, and suggest watching it periodically.

Why do this? Why look to space and understand Earth's smallness? So we can understand reality as Carl Sagan explains in his pale blue dot speech. ▶ this video

James May of Top Gear has flown with a U2 spy plane once [0][1]. When they reached to the edge of space, May said "If everybody could do that once, it would completely change the face of global politics, religion, education, everything". I can't agree more. Another thing I believe needs to be watched periodically is Pale Blue Dot [2]. [0]: link [1]: link [2]: ▶ this video

I'm hoping some of you can shed light on a few questions. It could be I've misunderstood what is meant by AGI. I thought AGI means an "agent" that can reason, strategize, solve problems, make judgments under uncertainty, apply common sense knowledge, learn, adapt, and alter its goals. With that in mind, I'm wondering: * Why would an AGI (malevolent or otherwise) risk war when there's an entire galaxy[1] they can explore and countless planets full of resources that they could use? * How can we ascribe super-human reasoning skills to an AGI in one breath, yet think the AGI would be content with making paper clips, collecting stamps, or smashing vases while cleaning, until heat death of the Universe in the next? * My limited understanding of warfare is that wars are sparked over resources or ideology (or both). Ideological differences notwithstanding, what resources are specific to Earth that humans and AGIs would have in contention? * Earth is only going to be habitable for another 500 million years before the Sun's expansion extinguishes most biological organisms (unless the planet's orbit is shifted). Wouldn't an AGI (abiotic or otherwise) be thinking in timelines that vastly outstrip our own? * In light of the previous answers, what purpose (end goal) do you imagine an AGI would give itself? * Why would that purpose involve enslaving or destroying humanity? Pointers to research papers would be most welcome (e.g., Von Neumann–Morgenstern utility theorem). [1]: ▶ this video (Pale B

> Because if the current atheist world is the real one, then we are doomed. We are in the death world. Game over. Thats it. All evidence points that this is true so far. What is wrong with that?

Ah, legacy. It always makes me happy to listen to Carl Sagan's words on his text "The Pale Blue Dot": From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again at that dot. That's here. That's home. That's us.

I'm sorry for your loss. When something bad happens I often find myself going back to Carl Sagan's words on the Pale Blue Dot [0]. Puts everything in perspective, and makes everything feel insignificant, when compared with the vastness of what lies out there. [0] ▶ this video

@Crazyontap2018 · in “Ask HN: Which audiobooks did/do you like?”

I really loved the Pale blue dot by Carl Sagan. His voice is soo smooth and relaxing that sometimes I just hear it for his voice even though the content is nothing less than amazing. P.S. Unfortunately Sagan died before the book recording could be completed so some chapters are in a different voice. Still, listening to it is real zen like. Here is a sample[1] [1] ▶ this video

> There's so much out there, just waiting for us to get off our duffs and explore. We have much of the technology; if we could just stop spending trillions on machines of war and instead spend it on machines of exploration.... I agree with this 100%. But while we're moving outward, however slowly, don't forget Sagan's Caveat: "Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand." Absolutely, go see what's across the street. But make sure your house is clean and safe. link Carl Sagan - Pale Blue Dot ▶ this video
