One day… our Sun will die. Everything we’ve ever known — every mountain, ocean, and living being — will vanish in silence. But how will it happen?” Right now, the Sun is a 4.6-billion-year-old star — halfway through its life. It burns hydrogen in its core, turning it into helium. That’s what keeps it shining… and keeps us alive.” But in about 5 billion years, it will run out of hydrogen. Then… chaos begins. The Sun will swell into a red giant, so huge it could swallow Mercury, Venus… and maybe even Earth. Oceans will boil, skies will burn, and our planet will melt.” After that, the Sun will shed its outer layers, creating a breathtaking planetary nebula — a glowing shell of gas, floating in space like a cosmic ghost. At its center, what remains will shrink into a white dwarf, no larger than Earth but a million times denser. It will no longer shine like a star — only faintly glow from the heat trapped inside. Eventually, even that light will fade. The Sun will become a black dwarf, cold… and dead.” So remember — every sunrise you see… is one of a finite number. Our Sun isn’t eternal. It’s just living on borrowed time.
