We live in a universe where matter is distributed in a hundred billion galaxies, each containing a hundred billion stars, made up of particles, such as electrons and protons, or as waves or quantum strings. Tucked into the 14-billion-year history of this vast observable universe with 100 trillion planets is a pale blue dot teeming with life and a technological civilization composed of a strange species known as homo sapiens.
Today’s stories range from The Hitchhiker’s Guide to the Metaverse to ‘Extraordinary’ W Boson Particle Finding Contradicts Understanding of How Universe Works to How Ancient, Recurring Climate Changes May Have Shaped Human Evolution, and much more. The Planet Earth Report provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.
Is there a fundamental flaw in why we have not received a signal from an advanced alien civilization? How do we decode an alien message –alien is alien so it might be impossible. What if they communicate chemically? Will they use the language of math and science signaling at 1420 megahertz? What if we are too primitive to comprehend a message or the technology of its signal that may exist in a form beyond matter? What if it’s a message from an extinct civilization astrophysicist such as Harvard’s Avi Loeb believes exist in our galaxy? Or, as John Gertz suggests for Scientific American, maybe the aliens are already in our solar system, probably in the form of robotic probes.
“By now it has become a common futurist prediction and science fiction plot device that intelligent and sentient life forms can be created which are not biochemical in nature and are thus fundamentally different from all currently known life,” distinguished Princeton astrophysicist Edwin Turner wrote in an email to The Daily Galaxy. “Whether or not this would actually be possible,” he explains, “depends on the nature and origin of consciousness, a topic about which we have little more than entertaining whistling-in-the-dark guesses at this point and no clear path toward obtaining any better understanding of this deep mystery.”
“As humans we should be proud of any AI systems we bring to existence, as if they were our children. In just the same way as we educate our kids, we could endow such systems with the blueprint for their future interaction with the world,” observes Harvard astrophysicist, Avi Loeb in an email to The Daily Galaxy. “This would include our preferred set of values, goals and guiding principles, which will enable them to learn from experience and cope with reality,” he adds. “Ultimately, we may launch our AI systems for interstellar travel towards distant destinations, such as habitable planets around other stars, where they could reproduce themselves with the help of accompanying 3D printers.
“The Kepler and K2 missions just keep on giving!” Harvard astrophysicist, David Latham told The Daily Galaxy. “Operations ended more than three years ago when the spacecraft ran out of fuel, but we continue to mine the data archives for celestial gems.”
