[Python] Million-Year Quantum Time Capsule

Here's a thought experiment about long-term data preservation:

The Problem
How do we communicate with civilizations 1M years in the future?

My Solution
A generator that creates "future-proof" images containing:

• [x] Universal constants (π, c, h)
• [x] Error correction
• [x] Galactic coordinates

import hashlib

Discussion Questions:

1. What would you include in a million-year time capsule?
2. How could we improve long-term data preservation?
3. Would universal constants still be meaningful to alien civilizations?
