Tidal-heating Memes

Jupiter's moon Io is basically the universe's punching bag, and it's stuck in an endless cycle of torment. See, Io is caught in a gravitational tug-of-war between Jupiter and its other moons (mainly Europa and Ganymede), which constantly squeezes and stretches the poor thing like cosmic Play-Doh. This process, called tidal heating, generates SO much internal friction that Io has become the most volcanically active body in our entire solar system—over 400 active volcanoes! So yeah, Io's entire existence is literally just getting crushed, erupting in volcanic fury, cooling down for a hot second, then getting crushed again. Rinse and repeat for billions of years. No peaceful lakes, no chill atmosphere, just perpetual geological screaming. It's like if your whole life was one continuous Monday morning, except the coffee machine is also a volcano. Talk about character development through trauma!
