You can click on my True Story of Easter from last year if you so wish, but on this day of resurrection, I am emboldened to suggest that Earth 2020 could well be a globe in economic shambles, so why not further predict that first contact will occur that year? I am re-visiting the Search for Extraterrestrial Intelligence (SETI) mostly because I saw in the morning paper an article on the Atacama Large Millimeter Array (ALMA) in Chile (above). This photo brought back vivid memories:
More than forty years ago, NASA's Project Cyclops began as a workshop of university professors led by Barney Oliver of Hewlett Packard and John Billingham of NASA's Ames Research Center (left). In 1972 they published their seminal work kicking off four decades of SETI. You can read the entire publication by clicking on Project Cyclops.
Two years later, the same people involved with the above effort provided funds to another group of university faculty--Jim Dator (below) and I from the University of Hawaii--for a public education program entitled, EARTH 2020: Visions for Our Children's Children. I was responsible for the first part, and Hans Mark (director of Ames) came up with the theme, enhancing a quote from Jane Stanford (she and her husband founded Stanford University).
Can you believe that in the summer of 1974 more than 2,000 people weekly jammed the NBC Concert Hall to listen to people like Garrett Harden ("Tragedy of the Commons") pontificate? To interact with these world thinkers, Jim and I selected an outstanding group of university and high school teachers, most who, like Phil Bossert, went on to become university presidents, legislators, principles, etc.
Then two years later, in 1976, I was invited by the originators of Project Cyclops to join yet another professorial team to Ames for Project Orion: A Design Study of a System for Detecting Extrasolar Planets.
Which, thirty six years later, brings me back full circle to 13March2012 when I attended a lecture by Nader Haghighipour of the Institute for Astronomy at the University of Hawaii on this subject. More specifically, I asked him to comment on a concept I had in 1976 advanced, with the aid of Charles Townes, to directly detect extrasolar planets. I await his analysis.
In those days no one had yet confirmed planets around other stars. Today, we now know there are many hundreds (now approaching 1000), and, speculated to be on the order of 160 billion, just in our galaxy. and there are, maybe, 500 billion other galaxies in our universe.
Evoking the dream of SETI, I finish with a quote from Frank Drake:
At this very minute, with almost absolute certainty, radio waves sent forth by other intelligent civilizations are falling on the earth. A telescope can be built that, pointed in the right place, and tuned to the right frequency, could discover these waves. Someday, from somewhere out among the stars, will come the answers to many of the oldest, most important, and most exciting questions mankind has asked.
