2. A framework we built to make sense of change.
3. We imagine it as an arrow: straight, forward, irreversible.
5. It gave us beginnings, endings and the story of progress.
6. Linear time feels like a race against a clock you cannot stop.
7. We measure, monetise and obsess over it; hence, time is money.
8. History itself was rewritten as a straight line of cause and effect.
9. Newton treated time as a universal constant, ticking the same everywhere.
10. Indeed, our lives are tied to this line: we plan, hustle, age and keep moving.
11. But many ancient and Eastern cultures saw something far more fluid and recurring.
12. They imagined time as a circle, rather than a line, where repetition was the natural order.
13. They found it in nature’s cycles: sunrises and sunsets, seasons, tides, moons, lifecycles.
14. Death, in this view, was never an ending at all, just a graceful curve in the circle of return.
15. Linear time brings urgency, warning that what goes now is gone forever, never to return.
16. Cyclical time brings comfort, suggesting that what disappears today will one day return.
17. Perhaps time is an illusion that moves us forward but folds itself into recurring patterns.
18. Or maybe time isn’t a line or a circle, but a spiral that returns to old points at higher levels.
19. Austin Kleon calls this the creative life: you loop back, but never quite to the same place again.
20. Physics expands this picture because it doesn’t give us a single story on time, but two different ones.
21. The second law of thermodynamics gives time its arrow because entropy, or disorder, always grows.
22. Which explains why eggs don’t unscramble, stars burn out and events and processes cannot be reversed.
23. Yet most fundamental laws of physics are time-symmetric; forward or backward makes no difference to them.
24. Which means the arrow of time isn’t its real essence at all; it’s merely a by-product of how matter behaves.
25. Time isn’t an arrow, circle or a spiral; it doesn’t flow or move, but provides the stage on which everything unfolds.
