11. Time Passes Differently in Space ⏰
Real Relativity
Fact:

Near a black hole, time almost stops.
Movie Interstellar:
1 hour on planet = 7 years on Earth (scientifically accurate).
12. The Moon Is Moving Away 🌙
Slow Goodbye
Rate:
1.5 inches per year.
Cause:
Gravitational interaction with Earth's tides.
Future:

- Total eclipses won't exist anymore
Past:
4 billion years ago, Moon was 10x closer.

Conclusion: We Are Insignificant and Special 🌟
Space reminds us that we are tiny on a cosmic scale, but also unique - as far as we know, we are the only intelligent life in the observable universe.
Lessons:
- Universe is stranger than imagination
- We are made of stars
- Earth is precious and fragile
- There's still much to discover
Every time you look at the night sky, you're seeing the past - starlight traveled years, decades, or millions of years to reach your eyes.
We are stardust contemplating stars. And that is absolutely incredible. 🌌✨
