I have to comment on this article, primarily because it has so spectacularly missed the point of the series and misrepresented my views on the importance of science, engineering and human progress. I'll do so by posting a few paragraphs from the Wonders of the Universe book, which Mr O'Neill would do well to read.
From the introduction:
The scientific project is ultimately modest: It doesn’t seek universal truths and it doesn’t seek absolutes; it simply seeks to understand, and therein lies its power and value. Science has given us the modern world, of that there can be no doubt. It has improved our lives beyond measure; increased life expectancy, decreased child mortality, eradicated many diseases and rendered many more impotent. It has given many of us the gift of time, freed us from the drudgery of mere survival and allowed us to open our minds and explore. Science is therefore a virtuous circle, its discoveries creating more time and wealth that we can, if we are wise, invest in further voyages of exploration and discovery. But for all its undoubted usefulness, I maintain that science is fuelled not by utilitarian desire but by curiosity. The exploration of the universe and its wonders is as important as the search for new medical treatments, new energy sources or new technologies, because ultimately all these valuable advances rest on an understanding of the basic laws that govern everything in nature, from atoms to black holes and everything in-between. This is why curiosity driven science is the most valuable of pursuits, and this is why we must continue our journey into the darkness.
And from the last page:
As the great astronomer Carl Sagan wrote:
“It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”
Just as we and all life on Earth stand on this tiny speck adrift in infinite space, so life in the universe will only exist for a fleeting, dazzling instant in infinite time, because life, just like the stars, is a temporary structure on the long road from order to disorder.
But that doesn’t make us insignificant, because life is the means by which the Universe can understand itself, if only for an instant. And this is what we’ve done in our brief moments on Planet Earth. We have sent space probes to the edge of our solar system and beyond; we have built telescopes that can glimpse the oldest and most distant stars and we have discovered and understood at least some of the natural laws that govern the cosmos. This, ultimately, is why I believe we’re important. Our true significance lies in our continuing desire to understand and explore this beautiful Universe.
