Fermi Paradox

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

The Great Silence
what would you need to have proved.
