Future Technologies — Zoom! … or Doom?

Astrophysicist Adam Frank sees a new role for us as galaxy gods as exhilarating but others aren’t so sure

Astrophysicist Adam Frank asks us to consider where we are on the Kardashev Scale for evaluating civilizations in the galaxy — or, at least, evaluating our own progress: Originally proposed in 1964 by Nikolai Kardashev (1932–2019) and later modified in 1973 by Carl Sagan (1934–1996), the scale measures a civilization’s technological advances from 1 to 3 (or maybe 5) by how much energy it can call upon to do things. Currently, we are not even a Type 1 on that scale and Frank offers some thoughts on that, asking, in particular, whether such advances are universal in the galaxy anyway: The classification scheme Kardashev used was not based on social systems of ethics because these are things that we can…

The Aurora Hypothesis: ET Could Risk Only Rare Contact With Us

Given the difficulties and risks of space travel, extraterrestrials with advanced technology may have visited Earth only one in a million years, researchers say

In recent months we’ve been looking at science writer Matt Williams’s coverage of the many reasons (links below) that have been advanced as to why we do not see extraterrestrials except at the movies. Last Saturday, we considered the Percolation Hypothesis, whose beauty is its common-sense simplicity: The aliens can’t overcome the laws of physics, any more than we can. In the real world, barriers like years between communications even at the speed of light would take a toll on adventurousness. Another hypothesis that Williams has examined is our focus today, the Aurora Hypothesis, “just because planets are habitable doesn’t mean that intelligent life can colonize there.” (Williams) The thesis has had a busy life in science media. Its earliest…
