Stephen Hawking predicted race of ‘superhumans’

Here’s a troubling insight from one of history’s great scientists, via The Guardian:

The late physicist and author Prof Stephen Hawking has caused controversy by suggesting a new race of superhumans could develop from wealthy people choosing to edit their and their children’s DNA.

Hawking, the author of A Brief History of Time, who died in March, made the predictions in a collection of articles and essays.

The scientist presented the possibility that genetic engineering could create a new species of superhuman that could destroy the rest of humanity. The essays, published in the Sunday Times, were written in preparation for a book that will be published on Tuesday.

Can’t help but remember this episode from Star Trek TOS:

Who can forget this blistering exchange between Spock and McCoy:

SPOCK: Hull surface is pitted with meteor scars. However, scanners make out a name. SS Botany Bay.
KIRK: Then you can check the registry.
SPOCK: No such vessel listed. Records of that period are fragmentary, however. The mid=1990s was the era of your last so-called World War.
MCCOY: The Eugenics Wars.
SPOCK: Of course. Your attempt to improve the race through selective breeding.
MCCOY: Now, wait a minute. Not our attempt, Mister Spock. A group of ambitious scientists. I’m sure you know the type. Devoted to logic, completely unemotional

The problem with selective breeding, as Spock later points out, is that “superior ability breeds superior ambition.” Instead of Ghandis and Einsteins, you get Hitlers and Napoleons.

Indeed, that’s the problem with all utopian schemes, from eugenics to communism — those pesky unforeseen consequences. Our minds evolved to adapt and survive in small social groups facing a harsh, unforgiving environment. The complex processes underlying the universe are beyond our grasp, just as our muscles are incapable of tossing boulders into orbit. Our muscles and our minds are not only useful, but extraordinary, but each have their limitations. True wisdom is the recognition and acceptance of those limitations.

That’s why we should heed Hawking’s last words.

Quote of the day

“‘Centrism’ is about eclecticism across time, not just across the partisan spectrum: I’m a ‘reactionary’ about some civilizational traditions that proved useful for centuries, but a ‘progressive’ about embracing many social & technological innovations.” Dr. Geoffrey Miller, evolutionary psychologist

Total Eclipse a once in a lifetime experience

Total Eclipse

My wife and I went to Congaree National Park just south of Columbia, South Carolina, to view the Totality. It was an experience I’ll never forget.

The park’s eclipse program began with a hike down a nature trail to the Congaree River. But we saw some gorgeous things along the way, including stunning wildflowers and General Greene’s tree.

General Greene's Tree

General Nathaniel Greene commanded the colonies’ Southern forces during the Revolutionary War, and crossed the Congaree near this spot on his way to confront the British in Charleston. This tree is over a thousand years old.

Here are two Golden Orb spiders we stumbled upon during our hike. The large female is just visible against the trees in the background. The hopeful, tiny male is clinging to the web just above her, waiting for the right moment. He probably doesn’t know what happens after the blessed event. We didn’t stick around to witness it.

We reached the viewing area on the eastern bank of the Congaree River. Even though we had ISO-approved solar viewing glasses, I relied mostly on my pinhole camera to watch the Moon’s progress. The camera worked great. The big advantage is that you can look at the image as long as you want. Even with the glasses, you should only gaze at the sun less than a minute at a time.

And you can always create your own hand-made crescents!

The light slowly dimmed, casting an eerie glow on the river and surrounding forests. Then, finally, the moon crossed directly in front of the sun, and we were enveloped in Totality. The air turned cool, and crickets began chirping.

That’s Venus emerging from the sudden darkness to the right of the Sun, now blocked off by the Moon.

Ten Minutes to Totality!

What a show! It was a thrilling, mysterious sight to behold, completely different from the partial eclipses I’ve seen. I’m glad we went.

Quote of the day

Flannery O'Connor

“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

Before you book that trip to Mars …

Mars

From Natural News:

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.

There is no Planet B.

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.
