The search for signs of intelligent life elsewhere in the universe should not only focus on detection of electromagnetic signals, but should also seek evidence of the physical artifacts that an intelligence life form might produce, a scientist at the Fermi National Accelerator Laboratory suggested in a paper (pdf) last month.
“Searching for signatures of cosmic-scale archaeological artifacts such as Dyson spheres or Kardashev civilizations is an interesting alternative to conventional SETI [Search for Extraterrestrial Intelligence, which searches for radio waves]. Uncovering such an artifact does not require the intentional transmission of a signal on the part of the original civilization. This type of search is called interstellar archaeology or sometimes cosmic archaeology.”
All of this of course is quite speculative, not to say whimsical. “With few exceptions interstellar archaeological signatures are clouded and beyond current technological capabilities,” the author notes.
But the concept and the logic behind it are explained with pleasant clarity in “Starry Messages: Searching for Signatures of Interstellar Archaeology” by Richard A. Carrigan, Jr., Fermi National Accelerator Laboratory, December 1, 2009.
A lack of sustained federal funding, deteriorating research infrastructure and networks, restrictive immigration policies, and waning international collaboration are driving this erosion into a full-scale “American Brain Drain.”
With 2000 nuclear weapons on alert, far more powerful than the first bomb tested in the Jornada Del Muerto during the Trinity Test 80 years ago, our world has been fundamentally altered.
As the United States continues nuclear modernization on all legs of its nuclear triad through the creation of new variants of warheads, missiles, and delivery platforms, examining the effects of nuclear weapons production on the public is ever more pressing.
“The first rule of government transformation is: there are a lot of rules. And there should be-ish. But we don’t need to wait for permission to rewrite them. Let’s go fix and build some things and show how it’s done.”
