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.
The Federation of American Scientists supports H.R. 471, the re-introduction of the Fix Our Forests Act.
As people become less able to distinguish between what is real and what is fake, it has become easier than ever to be misled by synthetic content, whether by accident or with malicious intent. This makes advancing alternative countermeasures, such as technical solutions, more vital than ever before.
Throughout this phase of work, there are many actions hiring managers and staffing specialists can take to streamline the process and improve the quality of eligible candidates. Most importantly, hiring managers and staffing specialists can collaborate within and across agencies to expedite and simplify the process.
The next administration should establish a Participatory Technology Assessment unit to ensure federal S&T decisions benefit society.
