Curiosity Pluto was once our 9th planet… until 2006. Now it’s a dwarf planet, smaller than Earth’s Moon. A single year there lasts 248 Earth years. Yet this tiny world has 5 moons, ice mountains, glaciers, and a giant heart-shaped region. ❄️❤️

[Heo Seongbeom Youtube] 260305 Jin - Moon 🌕🌏 (part1) 👨‍🏫It’s a solo song by Jin, and BTS are also preparing for a comeback in March. I’m really looking forward to it. I’m the moon, and you are the Earth. So it becomes a kind of love triangle. Earlier the sea loved the moon, but who does the moon love? The moon loves the Earth. That idea is reflected in this song, so let’s try interpreting it. Since when have the moon and the Earth been together like this? We’ve been together for so long, but when did it start? About 4.51 to 4.53 billion years ago. Scientists figured this out through radioactive isotope analysis, which showed that the Moon is about 4.51 to 4.53 billion years old. “Shining just by existing.” This line is directed at the Earth. But does the Earth actually shine just by existing? No. Because the Earth is a planet and does not produce its own light. If the Earth appears to shine, it’s probably because of artificial lights made by humans. “Can I stay by your side and protect you?” It sounds shy, but in reality the moon can’t help staying there, because it’s bound by gravity. And here we see the main line of the song. “You are my Earth, and to you I’m just a moon. Your small star that lights up your heart.” It’s poetic, but is the moon actually a star? No. Celestial bodies are generally divided into two categories. First, there are stars (stellar bodies). These produce their own light. Second, there are planets. Planets do not produce their own light. Instead, planets usually orbit around a star. The Earth is a planet. From our perspective, the star in our system is the Sun. So when you look at the night sky and see stars, those lights are actually other suns, each producing their own light. But sometimes when you see a particularly bright “star,” it may actually be a planet like Mercury, Venus, Mars, or Jupiter. Then you might ask: if planets don’t produce their own light, why do they shine? Because they reflect sunlight. The Moon also appears bright because it reflects the Sun’s light. #JIN #방탄소년단진 방탄소년단

Jeff Bezos just described the Moon as a fuel depot, and the number behind it explains why nothing has ever left this planet cheaply. Bezos: “it has a very low gravitational field, only a sixth of Earth’s, which means it takes about 30 times less energy to lift a kilogram of mass off the Moon than it does to lift it off the Earth.” Thirty to one. That number rewrites the economics of everything beyond this planet. Every rocket ever launched has fought the same math. The fuel required to escape Earth is so heavy that most of what a rocket carries is the fuel needed to carry the fuel. The Moon breaks that cycle. It sits outside the well with water frozen in its shadowed craters, and water splits into hydrogen and oxygen. Hydrogen and oxygen are rocket fuel. Bezos: “the Moon is really a gift” Fill the tank up there instead of down here and the arithmetic of the entire solar system changes. Bezos: “So we can use the Moon as a rocket fuel depot to go to the rest of the solar system.” Not a destination. A gas station. Then there is the second constraint, which is that the sky itself runs on a schedule. Bezos: “unfortunately to get to other planetary bodies, they have very rare launch windows. Mars, you can go to Mars once every 26 months or so.” Miss the window and the answer is not next week. It is two years and change. Every world beyond our own operates on a timetable that does not care about human ambition. Bezos: “It’s so close to Earth. It’s only three and a half days away.” Except the Moon. The Moon is always there. Always reachable. That is what makes it the staging ground rather than the trophy. Apollo treated it as an endpoint, planted a flag, and came home. The flag was the mistake. A gas station is worth more than a monument. Monuments end the story. Infrastructure is what lets everyone who comes after take the trip for granted. Every era of exploration on Earth followed the same shape. Someone crossed once for glory, then someone built a port, and only after the port did ordinary people go. We have been staring at the Moon for three hundred thousand years thinking it was a destination. It was never the destination. It was the door. Every planet in the solar system just got closer. Not because the distances changed, but because the starting point did.

✅Explanation of Meaning (by parts): 1. “During the inception of our Universe, fortuitously arose a small possibility” : The author begins by noting that at the Universe’s origin, a slight chance emerged for the potential development of intelligence, framing this as a fortunate but improbable event inherent to cosmic conditions. 2. “that under certain circumstances there might come into existence at least a single primitive intelligent being” : This possibility hinged on specific conditions allowing for the emergence of even one basic intelligent entity, emphasizing the delicate and rare circumstances required for intelligence to arise. 3. “The planet upon which this would occur remained a mystery” : The author highlights that the specific location for this emergence was unknown, suggesting that no particular planet, including Earth, was predestined to host intelligence, reinforcing the randomness of the event. 4. “and the emergence of intelligence on Earth is not miraculous” : The development of intelligent life on Earth is presented as non-miraculous, a natural outcome of cosmic processes rather than a divine or extraordinary occurrence, grounded in chance. 5. “This could have materialized on another celestial body” : The author notes that intelligence could have arisen elsewhere in the Universe, on another planet or moon, underscoring the non-exclusive nature of Earth’s role in hosting intelligent life. 6. “and a thinking being similar to us would likewise ponder: why us, why here?” : If intelligence emerged elsewhere, those beings would ask the same existential questions as humans, reflecting on their own existence and location, highlighting a universal curiosity among intelligent life. 7. “It’s a matter of chance, you’re simply fortunate, your planet won the cosmic lottery” : The author concludes that the emergence of intelligence is purely a matter of luck, with Earth’s success likened to winning a cosmic lottery, emphasizing the role of random chance in our existence. 🗝️Main Idea (refined version): The author posits that the Universe’s inception held a faint chance for intelligence to emerge under rare conditions, with Earth’s hosting of intelligent life being a non-miraculous outcome of cosmic chance. This could have occurred elsewhere, and any intelligent beings would question their existence, as we do. Our presence is a fortunate accident, Earth having won the cosmic lottery, prompting humility and curiosity about our place in a random, vast Universe. This perspective challenges us to embrace the improbability of our existence, fostering a sense of awe and responsibility to explore and understand the cosmos.
