**Title:** The Scale of the Universe: From Earth to the Unknown
**Summary:**
* The text takes the reader on a zoomed-out journey from Earth to the observable universe, highlighting the vast scales of our cosmos.
* Key stops include:
1. **The Moon**: 384,400 km away, with 12 humans having visited.
2. **Mars**: 225 million km away, with a 20-minute communication delay.
3. **Voyager 1**: The farthest human-made object, 138 AU from Earth, with a iconic "Pale Blue Dot" photo of Earth.
4. **Proxima Centauri**: The closest star outside our solar system, 4.24 light-years away.
5. **The Milky Way Galaxy**: Containing 100 billion stars and planets, spanning 100,000 light-years.
6. **The Observable Universe**: Encompassing 2 trillion galaxies, with a diameter of 93 billion light-years.
* The text concludes by speculating on the existence of a much larger universe beyond the observable one, potentially 150 sextillion times larger, and encouraging exploration and discovery of the unknown.
