Extraordinary claims. Ordinary investigations.

Fermi, what paradox?

According to physicist Robert A. Freitas, Jr., There Is No Fermi Paradox:

Less than 10% of the Earth’s surface, 1% of the Moon, 0.1% of Mars, and 10-7% of Venus (total 5 x 107 km2) has been surveyed to 1- to 10-m visible resolution. This leaves 99.96% of Solar System surface area (1.3 x 1011 km2) unexamined for likely artifacts. Interplanetary spacecraft and ground-based telescopes have photographed portions of some planets and asteroids down to 20-km resolution, plus a few tracts on some outer planet moons to 1-10 km. Objects buried or submerged are undetectable with current instrumentation. Large artificial habitats in the asteroid belt (Papagiannis, 1978) would appear visually indistinguishable from natural objects, especially since the belt population itself is poorly cataloged. The assertion that a resident artifact would alert us to its presence is an unwarranted, unsupportable, and untenable assumption.

Very reasonable. In my humble opinion, assuming a galactic civilization would be noticed is not that unwarranted, unsupportable nor untenable, but it’s indeed necessary to remind just how limited our search for extraterrestrial intelligence has been so far.

We can only discard with some confidence civilizations of Type III. But there may still be some Type II civilizations out there, and possibly countless of Type I. We would still not be noticing them. The Fermi Paradox assumes at least one civilization should have evolved to Type III by now.

We are still Type 0! Nada!
