The Science Of Aliens

by Clifford A Pickover

Overview

If extraterrestrials ever landed on Earth, they would find us extremely strange. Their first intimation of our existence might well be a Super Bowl broadcast or a stray transmission from the Playboy channel. But, of course, they might seem equally strange to us. How strange? Their senses could be entirely different from ours—they might see in the infrared or “hear” radio waves.What would aliens look like? An intelligent octopus-like creature is certainly plausible. What about odd numbers of limbs—a three-legged alien with three arms and three eyes? What about an entire planet of immobile, silicon-based “trees” that communicate with each other via electrical signals?The Science of Aliens gets weirder still. Could a giant interstellar cloud be “alive” and intelligent? Could creatures live at extremely high pressures and temperatures? And which of these many possibilities would be similar enough to us that they could communicate with them, or they with us? Would they have any interest in abducting us? Would they want to have sex with us? In classic Pickover style, here is speculation at the far edge of knowledge—and beyond.

In his song "Farmer's Almanac," Johnny Cash sings these beautiful words: "God gave us the darkness so we could see the stars." I kept repeating Cash's verse on stars as I wrote The Stars of Heaven. As with many of my books, The Stars of Heaven is meant to stretch your imagination and touch on subjects on the edges of science, art, and even religion. Let me tell you how the book started...

A few years ago I was walking in a field when I came upon a large skull. It was probably from a bear, although I like to imagine it was part of the remains of a prehistoric mammal that once roamed Westchester County, New York. I'm a collector of prehistoric skulls. In my office, I have a skull of a saber-toothed tiger. This killing machine had huge, daggerlike canine teeth and a mouth that could open 90 degrees to clear the sabers for their killing bite.

When I run my fingers lingeringly over the skulls, I am sometimes reminded of stars in the heavens. Without stars, there could be no skulls. The elements in bone, like calcium, were first created in the hot stellar furnaces and then blown into space when the stars died. Without stars there would be no elements heavier than hydrogen and helium, and, therefore, life would never have evolved. There would be no planets, no microbes, no plants, no tigers, no humans.

In my book, you'll do a little armchair space travel, rub elbows with alien life forms, and glimpse the furthest corners of our uncharted universe. Stars have fascinated humankind since the dawn of history and have allowed us to transcend ordinary lives in our literature, art, and religion. Where did we come from? What is the universe's ultimate fate? Are there other universes we can never see? Was our universe designed by a god?

In about 5 billion years, the hydrogen fuel in our sun will be exhausted in its core, and the sun will begin to die and dramatically expand, becoming a red giant. At some point, our oceans will boil away. As Freeman Dyson once said, "No matter how deep we burrow into the Earth...we can only postpone by a few million years our miserable end." Where will humans be, a few billion years from now, at the end of the world? It seems so sad. However, I don't think we have to mourn for humanity. In a few billion years, humans will probably have downloaded their minds to computers, left the solar system in some great diaspora, and sought their salvation in the stars.

You can tell that my book is an amalgam of science fiction, science fact, religion, art and science. It's also a serious astronomy primer covering all the basics of stellar structure and evolution and also on creative theories about our place in this grand universe. I've touched on similar cosmic topics on the borderlands of science before, and I hope you'll take a look at some of my other books, for example: Black Holes: A Traveler's Guide, Time: A Traveler's Guide, Surfing Through Hyperspace, The Science of Aliens, and The Paradox of God and the Science of Omniscience. Please visit my web page, Pickover.com, and join our discussions on The Stars of Heaven and all my other books. I leave you with an appropriate Serbian proverb to get your mind in gear: "Be humble for you are made of dung. Be noble for you are made of stars." (Clifford Pickover)
