A mere week after NASA scientists announced their certainty of finding life on other planets within the next 20 years, a team of other scientists announced that, after searching 100,000 galaxies, they have found no signs of at least intelligent extraterrestrial life.
The researchers used information from NASA’s Wide-field Infrared Survey Explorer orbiting observatory (WISE) to look for energy radiating away as heat. “The idea behind our research is that if an entire galaxy had been colonized by an advanced … civilization, the energy produced… would be detectable in mid-infrared wavelengths,” explained Jason T. Wright, a Penn State University professor who initiated the survey. “These galaxies are [many] years old,” he continued, “which should have been plenty of time for them to have been filled with alien civilizations.”
This search is nothing new. Over the 1960s and 1970s, there was SETI, or the “Search for Extra-Terrestrial Intelligence”; META, the “Megachannel Extra-Terrestrial Assay”; and META II. In 1972 and 1973, plaques depicting information about Earth were launched aboard the Pioneer and Voyager probes. In 1974, the “Arecibo message,” which carried coded information about chemistry and terrestrial life, was beamed into space. And in the 1990s, the “Billion-channel ExtraTerrestrial Assay” (BETA) was created, as well as a project harnessing the computing power of five million volunteers’ computers to crunch numbers that might reveal patterns indicative of intelligent life beyond our planet. Tens of billions of hours of processing time were consumed by the project.
So far, though, nothing. No little green men. Not even any green slime.
True, for 17 years, astrophysicists monitoring Australia’s Parkes telescope detected strange radio bursts signals, which were believed to come from another galaxy. Recently, though, Emily Petroff, a Ph.D. student working at the facility, showed that the signals were being generated by a microwave oven in its kitchen.
The prime candidate for rudimentary life in our own solar system, of course, is Mars. Thus far, though, the four rovers that have been sent to the red planet haven’t discovered any of the molecules considered by scientists to be the “building blocks of life,” much less life itself.
Still, many scientists say there must be life out there. Science doesn’t usually embrace beliefs unsupported by observations. So, whence their conviction that there must be life elsewhere in the universe? The answer is that it derives from a creed: that chance governs the universe – that randomness lies at the root of reality.
If probability, not design, is the loom on which the universe’s fabric is stretched, that creed’s canon proclaims, why should there be only a single, unremarkable planet in a single, unremarkable solar system in a single, unremarkable galaxy where there is life?
The high priests of Scientism even believe in miracles, as in their contention that life on Earth arose by chance from inanimate matter, something that, of course, has never been accomplished despite valiant efforts, in the lab. And that the astounding diversity of life emerged randomly. And so, the creed reasons, why shouldn’t countless other worlds have done any less?
We, of course, know that Creation, including life, was an act of Divine Will, not the yield of randomness. To be sure, were life to be discovered on some other planet, it wouldn’t challenge us any more than the fact that life was discovered here on earth in hot springs and deep-sea vents, long assumed to be devoid of living creatures.
But intelligent life elsewhere in the cosmos? Unlikely. One thing is certain: All efforts to detect it have come up empty.
The Torah (Devarim, 17:3) speaks of a false prophet who will “prostrate himself … to the sun or the moon or to any host of heaven, which I have not commanded.” Rashi explains that last phrase as meaning “which I have not commanded you to worship.”
Reb Levi Yitzchok of Berditchev had a profound interpretation of that Rashi.
The reason one may not bow down to a heavenly body, he explained, is because they have not “been commanded” — they lack the free will necessary to accept or reject a Divine commandment. One may, however, bow down in respect to a human being — because humans are singular, sublime creatures, beings who have been commanded, who uniquely possess the free will to accept and execute Hashem’s will.
So far, at least, such choosing beings are only known here on Earth. Might there be intelligent extraterrestrials?
I imagine some may “hear” such a possibility.
Personally, though, I think the silence out there speaks much more loudly.
