What If a Tree Never Stopped Growing?

You're 10. You plant a 70 cm sapling in your backyard. Every year, it doubles in size. That's the only rule. By 15 it's taller than every tree on the block. At 17 it passes the tallest tree on Earth. At 27 it reaches space. And on your 100th birthday, it's bigger than the observable universe. 🌳🌍🌌 How old did YOU guess you'd be when it reached space?

Doubling is sneaky: after 10 years the tree is about 1,000× taller (2^10 = 1,024), after 20 years about a million times taller, and after 90 years about 10^27 times taller. That's exponential growth. This is an animated what-if scenario. Real trees do not grow this way. #whatif #exponentialgrowth #tree
