Cosmos Revealed: The Truth Is Out There, Again and Again
Pacific News Service, Commentary, Andrew Lam, Posted: Dec 31, 2003
Editor's Note: Recent discoveries suggest life itself may be commonplace in the universe. But far from constraining spiritual imagination, science's wondrous new findings reveal mysteries ever more sublime.
Though barely middle aged, I am old enough to remember a time when Earth was just a lonely blue planet amid the heavens. I remember, too, that precise moment when man's gaze turned upward, in awe. It was the summer of 1969, and I was a child living in Vietnam. But on TV, instead of the regular news about the war, three peculiar creatures danced on a barren landscape.
Until that moment, I had believed what my grandmother told me: that a beautiful moon goddess resided on the silver globe that hung outside my window. But by stirring up the lunar dust with their metallic boots, the American astronauts effectively debunked her corporeal existence.
In her place is a radical shift in human psyche regarding its relationship with the rest of universe.
Consider these astonishing discoveries made in the last decade:
--Using the Hubble Telescope, which orbits Earth, astronomers have discovered other solar systems -- planets going around stars. One planet in particular is believed to have an atmosphere.
--We know that Earth is constantly bombarded by meteors when we look up into the night sky and spot shooting stars. But more astounding is what astronomer Lou Frank speculated about a decade ago and found new evidence for only recently. Using the Hubble Telescope to study Earth's atmosphere, Frank proved that Earth is constantly hit by snowballs from space. The implications are enormous: if snowballs from outer space hit Earth regularly, it is "snowing" elsewhere also, onto other planets, providing much-needed water for the primordial soup.
--A few years ago a meteorite from Mars found on Earth, known as the Allan Hills meteorite (or ALH 84001 to scientists), astonished everyone when some scientists claimed they found tantalizing traces of fossilized life within it. Their findings have been contested, but the meteorite renewed enthusiasm for the idea of panspermia (Gr: all-seeding) -- the interstellar exchange of DNA, a theory that was championed by Francis Crick, who discovered the DNA molecule with two other scientists half a century ago.
--The Galileo space probe that orbited Jupiter showed us that on Europa, one of Jupiter's many moons, huge oceans lie beneath an icy surface, as well as active volcanoes -- that is to say, the ingredients that could spark and possibly support life.
Until quite recently, we humans have been egocentric when explaining our place in the universe. Half a millennium ago we assumed our world was the universe's center -- and, for that matter, flat -- and that the sun orbited Earth. Last century we held on to the notion that our solar system was unique. Scientists just a generation ago assumed, too, that conditions on Earth -- a protective atmosphere, ample water and volcanic activity -- made it the only planet that could possibly support life.
That sense of self-importance has given way to a more humble assessment of our place in space. The conditions on our home planet may be unique, but solar systems are not at all anomalies. We are in the process of accepting that we are very much part of larger universe. Furthermore, we are -- by sending space probes to the edge of the solar system, by collecting moon rocks and comet dust, by landing probes on Mars to dig for soils and search for signs of life, and by planning manned missions to Mars -- in constant exchange with the universe.
These days many scientists dare to believe that we are not alone. Take astronomer Segio Fajardo-Acosta, a research associate at University of Denver. He believes many civilizations exist in the universe. "The distances are staggering and communication is a problem, especially if that civilization is in another galaxy," Fajardo-Acosta writes. "But with imagination and a very sophisticated technology, I think we could probably overcome the distance limitation and communicate with others."
Nietszche asked rhetorically, "Have you not heard that God is dead?" Galileo, Newton, Einstein and the like had revealed a universe more startling than any ancient myth could describe.
But it is my contention that science, even as it slays the old gods, does not destroy human spirituality. Quite the contrary: in the cosmic age, science and spirituality reinforce each other. Science chips away at our ancient myths, only to reveal even greater mysteries. The more science reveals, the more mysterious and sublime the revelation.
On the eve of two NASA spacecraft missions to Mars in search of signs of life this January, space exploration should fill us all with a renewed sense of wonder. The sea on which humanity now sails is infinitely more vast and wondrous than that imagined by Columbus. And though wars and famines and diseases still grip mankind, when we look upward, it seems that there's ample grace waiting in the heavens.
