The Fermi paradox is the discrepancy between the lack of
conclusive evidence of advanced extraterrestrial life and
the apparently high likelihood of its existenceThe following are some of the facts and hypotheses that
together serve to highlight the apparent contradiction:
There are billions of stars in the Milky Way similar to the
Sun .
With high probability, some of these stars have Earth-like
planets in a circumstellar habitable zone .
Many of these stars, and hence their planets, are much
older than the Sun. If Earth-like planets are
typical, some may have developed intelligent life long
ago.
Some of these civilizations may have developed
interstellar travel, a step humans are investigating now.
Even at the slow pace of currently envisioned interstellar
travel, the Milky Way galaxy could be completely
traversed in a few million years.
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.
However, there is no convincing evidence that this has
happened.
