“Since the eighteenth century, the popular spirit of each succeeding age has tended more and more to the view that the ills and mysteries of life will eventually fall before the scientific advances of man, a belief that is still going strong even though this is the first generation to face total extinction because of these advances.” – Flannery O’Connor

The idea of heading out to space and traveling to the red planet is thrilling but consider this for a moment: Going to Mars significantly increases your chances of acquiring cancer. That’s what the latest study published in Scientific Reports concluded. Cancer risk for humans who go on a mission to Mars or on long-term space missions doubled because of exposure to radiation from cosmic rays. Being away from the protection of Earth’s magnetic field increased the risk of radiation because cosmic rays which contain iron and titanium atoms severely damage the cells due to very high rates of ionization.
That’s a fascinating and well-done article, so you’ll want to read the whole thing, but here’s the bottom line: There is no Planet B.
Occasionally, I’ll hear from science fiction aficionados who fancy that one day, humans will spread out across the galaxy. We must, they say, because when Earth dies, we’ll just blast off and leave this old burned-out hulk behind for new, more exciting worlds. Problem is, even if we proved Einstein wrong and developed faster-than-light travel, we can’t just pack up and leave Earth the way we can move to other states or countries.
The beautiful planet we’re on is where we originated, and where we live. We used to think people were autonomous entities, but in fact, our lives depend on Earth’s many processes. It hasn’t been that long that we’ve come to appreciate the existence and our relationship with gut flora, which help regulate our immune system, our digestion, and even the way our minds work. And look at the essential relationship we have with mitochondria, those living things with their own DNA, and without which we could not function.
We’re not monads, those free-floating, ultimately simple entities cooked up by rationalistic philosophers. We’re humans, evolved beings with deep, deep roots in the natural world, and here is where we were meant to be.
“I always thought that the mark of person with deep understanding is that he or she can explain things in simple terms.” Dr. George Stanciu, theoretical physicist
From Scientific American:
Noam Chomsky’s political views attract so much attention that it’s easy to forget he’s a scientist, one of the most influential who ever lived. Beginning in the 1950s, Chomsky contended that all humans possess an innate capacity for language, activated in infancy by minimal environmental stimuli. He has elaborated and revised his theory of language acquisition ever since.
It’s a great article, and includes an interview with another accomplished linguist, Steven Pinker. Pinker concludes that even after decades of brutal examination and criticism, Chomsky’s famous thesis best explains how children master language. The alternatives boil down to arguing that language is an artificial construct of the rational mind that children, starting from a blank slate, must learn.
This vindication of Chomsky’s universal grammar theory is interesting on two counts, and both impact my writing. First, I’m fascinated by language. More important, scientific support of language as an inborn capability bolsters the view that people are naturally social, as opposed to the atomistic, rationalistic view of humanity pushed by both Hobbesians and Marxists.
“There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art science would be as useless as a pair of high forceps in the hands of a plumber. Without science art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.” – Raymond Chandler
“You start by loving a subject. Birds, probability theory, explosives, stars, differential equations, storm fronts, sign language, swallowtail butterflies—the odds are that the obsession will have begun in childhood. The subject will be your lodestar and give sanctuary in the shifting mental universe.” E. O. Wilson
