A Popfront contributor wrote how scientists and businessmen project our economic system onto the stars:
Have you ever seen an alien? Scientists haven’t, but that hasn’t stopped them from speculating that imperialist extraterrestrials could be on the way.
With the exception of one inconclusive blip in 1977, we haven’t detected signs of alien intelligence. Having scoured our solar system with probes and turned up empty, extraterrestrial (ET) signal searchers now survey the galaxy on the radio portion of the electromagnetic spectrum, where photons can traverse interstellar distances and arrive on Earth unscathed.
The most prominent and well-funded organized effort to search radio bands is led by the SETI (Search for Extraterrestrial Intelligence) Institute, a private nonprofit foundation that borrows time on radio telescopes or scans the skies using their own arrays.
While the SETI Institute has been actively searching for forty years, there have been few attempts to send out focused radio signals of our own towards presumptive inhabited worlds. This poses a conundrum: why should humans expect aliens to send out focused “hello” signals of their own, if we do not do it ourselves? This idea, that we should send out messages in addition to listen for them, is known as “Active SETI.” Continue reading →
Is interstellar space travel a Western, colonialist fantasy?
considered: Interstellar (2014)
Directed by Christopher Nolan
Starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, Michael Caine, Bill Irwin, and Ellen Burstyn
The collective consciousness of Wikipedia, in their plot summary of Interstellar, wrote1 that the film’s version of the USA depicts an “agrarian, stateless society.” In Nolan’s not-so-distant-future, America is ravaged by Dust Bowl-size superstorms, crop failures are abundant, and Big Government is a thing of the past—indeed, there’s hardly any government at all, save an allusion to a “federal” textbook. In this world, where the conspiratorial, anti-government pundits seem to have won, the moon landings are widely regarded to have been faked. (Professional conspiracy-mongerers like Alex Jones and Glenn Beck have reason to smile at this.) Continue reading →
