AHA! Cosmic Moment — How Old Is the Sky? When Humans Learned the Universe Has a Birthday

 

For thousands of years, people thought the universe was like an endless playlist — no beginning, no end. But modern science hit pause and said, “Wait, it actually started!” Edwin Hubble spotted galaxies moving apart, proving the universe is expanding. Roll back the cosmic tape, and boom — the Big Bang, about 13.8 billion years ago.

This comic flips the sky from a boring wallpaper into a cosmic timeline. Every star you see tonight is ancient light, traveling billions of years just to photobomb your eyeballs. In Chinese culture, the sky is called “Lao Tian” (Old Heaven), which kinda nails the vibe: the sky is definitely not young.

Physics teaches us the universe has an age. Life teaches us to treasure our short cameo in this epic story. And for you, young ones grinding through SPM exams — your days are just a blink in cosmic time. So the big question is: how will you use your blink?
