# Critique of the Fermi Paradox
|
||||
|
||||
## The Fermi Paradox: Key Points
|
||||
|
||||
1. **Abundance of Stars**
|
||||
There are billions of stars in the Milky Way similar to the Sun.
|
||||
|
||||
2. **Habitability of Planets**
|
||||
With high probability, some of these stars have Earth-like planets in a circumstellar habitable zone.
|
||||
|
||||
3. **Ancient Planets**
|
||||
Many of these stars—and thus their planets—are much older than the Sun. If Earth-like planets are typical, some may have developed intelligent life long ago.
|
||||
|
||||
4. **Potential for Interstellar Travel**
|
||||
Some of these civilizations may have developed interstellar travel, a step humans are investigating now.
|
||||
|
||||
5. **Galactic Exploration Timeframe**
|
||||
Even at the slow pace of currently envisioned interstellar travel, the Milky Way galaxy could be completely traversed in a few million years.
|
||||
|
||||
6. **The Expectation of Contact**
|
||||
Since many of the Sun-like stars are billions of years older than the Sun, the Earth should have already been visited by extraterrestrial civilizations—or at least their probes.
|
||||
|
||||
7. **The Great Silence**
|
||||
However, there is no convincing evidence that this has happened.
|
||||
|
||||
|
||||
## The Fermi Paradox: Key Issues
|
||||
|
||||
|
||||
**Ancient Planets**
|
||||
This should be 2 points as 3a 3b.
|
||||
3b is then some may have developed life long ago - intelligence and life are not imutable.
|
||||
|
||||
**Potential for Interstellar Travel**
|
||||
We dont need travel just radio waves
|
||||
|
||||
**Galactic Exploration Timeframe**
|
||||
radio waves - a few decades at most
|
||||
|
||||
**The Expectation of Contact**
