THE WORLD AROUND US 11 Mountain Views-News Saturday, January 14, 2017 PREPARING THE WAY FOR THE FIRST INTERSTELLAR FLIGHT The European Southern Observatory (ESO) has signed an agreement with the Breakthrough Initiatives to adapt the Very Large Telescope instrumentation in Chile to conduct a search for planets in the nearby star system Alpha Centauri. Such planets could be the targets for an eventual launch of miniature space probes to Alpha Centauri by the Breakthrough Starshot initiative. The discovery in 2016 of a planet, Proxima b, around Proxima Centauri, the third and faintest star of the Alpha Centauri system, adds even further impetus to this search. Knowing where the nearest exoplanets are is of paramount interest for Breakthrough Starshot, a research and engineering program launched in April 2016, which aims to demonstrate proof of concept for ultra-fast light-driven “nanocraft,” laying the foundation for the first launch to Alpha Centauri within a generation. Detecting a habitable planet is an enormous challenge due to the brightness of the planetary system’s host star, which tends to overwhelm the relatively dim planets. One way to make this easier is to observe in the mid-infrared wavelength range, where the thermal glow from an orbiting planet greatly reduces the brightness gap between it and its host star. But even in the mid-infrared, the star remains millions of times brighter than the planets to be detected, which calls for a dedicated technique to reduce the blinding stellar light. Detecting and studying potentially habitable planets orbiting other stars will be one of the main scientific goals of the upcoming European Extremely Large Telescope (E-ELT, http://www. eso.org/e-elt). Although the increased size of the E-ELT will be essential to obtaining an image of a planet at larger distances in the Milky Way, the light collecting power of the VLT is just sufficient to image a planet around the nearest star, Alpha Centauri. BREAKTHROUGH STARSHOT is a $100 million research and engineering program aiming to demonstrate proof of concept for a new technology, enabling ultra-light unmanned space flight at 20% of the speed of light, and to lay the foundations for a flyby mission to Alpha Centauri within a generation. The Starshot concept envisions launching a “mothership” carrying about a thousand tiny spacecraft (on the scale of centimeters) to a high- altitude orbit and then deploying them. Ground- based lasers would then focus a light beam on the crafts’ solar sails to accelerate them one by one to the target speed within 10 minutes. If an Earth-size planet is orbiting within the Alpha Centauri system’s habitable zones, Breakthrough Starshot will try to aim its spacecraft within 1 astronomical unit (the Earth-Sun distance, or 93 million miles) of it. From this distance, a craft’s cameras could potentially capture an image of high enough quality to resolve surface features. The fleet would have about 1000 spacecraft, and each one (dubbed a StarChip) would be a very small centimeter-sized vehicle weighing a few grams. The spacecraft would be propelled by a square- kilometre array of 10-kilowatt ground-based lasers with a combined output of up to 100 gigawatts. Each spacecraft would transmit data back to Earth using a compact on-board laser communications system using its solar sail as an antenna and the propulsion array as the receiver. A swarm of about 1000 units would compensate for losses caused by interstellar dust collisions en route to the target.[ You can contact Bob Eklund at: b.eklund@ MtnViewsNews.com. OUT TO PASTOR A Weekly Religion Column by Rev. James Snyder CHRISTOPHER Nyerges “THE LORD OF THE FLIES” EVERYTHING OLD IS GETTING OLDER STILL [Nyerges has led wilderness and wild food field trips for over 40 years. He is the author of numerous books, including “How to Survive Anywhere,” “Extreme Simplicity,” “Guide to Wild Foods,” and others. Questions about his classes and books can be directed to www.SchoolofSelf-Reliance.com or Box 41834, Eagle Rock, CA 90041.] A plane crashes on some remote island, and only the British school children survive. A classic story of survival begins. The boys –after having attended not a single “survival school” -- learn to hunt, make shelters, make fire (using Piggy’s spectacles, or eye glasses), and to enjoy themselves. After all, with all the adults gone, there’s no one to enforce rules, so we do what we want, right? Then the battle for power begins. One side is for some sort of orderly life, and the other side wants to live by rule of might. “Lord of the Flies” has been widely viewed and widely discussed. What does it mean? What does it tell us about our basic human nature? Is our desire to do good and cooperate with others a skill that must be learned and maintained? Are we essentially animals who need to learn to control our animal natures? The movie (and book) begins with the boys experiencing a sort of innocent paradise, as they swim and cavort and learn about foods in their adult-free world. The obvious need for leadership results in a vote between Ralph, who represents order and the rule of law, and Jack, who represents immediate fulfillment of desires, power, and even savagery. Ralph wins the election. In the beginning, Ralph and Jack are not depicted as being all that different. Indeed, they are friends. Ralph is set on doing the best for all, helping the weak, making sure that everyone is fed. Jack seems more intent on his own power ambitions. A conch shell is chosen as a sign of leadership, and an indication of who has the “floor” during meetings. But Jack forms his own band and moves away from Ralph. Jack chooses to disregard the blowing of the conch. That choice leads to further division and animosity. Eventually, the conch is destroyed when a boulder rolls onto it, symbolizing the loss of one of the symbols of their chosen civility, somewhat akin to someone in a board meeting tossing the gavel out the window. Jack’s group steals Piggy’s specs to make fire, another strike at cooperation and civility. Jack’s group also lets the signal fire go out, showing that Jack has lost his focus of trying to get off the island. In analyzing The Lord of the Flies, countless analogies have been used to describe the social dichotomy that it depicts, such as users vs. takers, or producers vs. consumers, or urban vs. rural, or primitive vs. civilized, etc. Perhaps it is the same old story of Cain vs. Abel, or the farmers vs. the ranchers. The story has even been used to illustrate political parties in various countries. But is it that simplistic? Jack and his group finally devolved to the point where murder was justified. Jack and his group started to hunt Ralph. Jack’s desire for total power would be solidified with the elimination of Ralph (the last opposing force). As Jack’s group chases Ralph along the beach, they all confront a force they all have to reckon with – the rescuing sailors. The sailors are tall, dressed in white, somber. It’s as if the children butted up against the gods of the universe, and now the day of reckoning comes. A group of men landed on the island and watch in amazement at the behavior of the “children”. The look on the children’s faces express their thoughts. Jack realizes his reign as a petty tyrant in his island empire is over; Ralph is relieved his life is saved, and now he’ll be going back to his real home. We see something in the childrens’ faces: now they have to account for their actions to a higher power. The choices that each of us make in life have ramification that ripple through our lives. “Ralph” and “Jack” represent the choices we make. What legacy will we leave? What actions will we ultimately be accountable for when the sailors get to shore? The amateur film-makers who created the original “Lord of the Flies” did so during the boys’ summer vacation. They tracked the lives of the boys who acted in this movie, and the boy- actors were all high achievers in their personal lives. The boys later related that making the movie deeply affected them. Even though it was described as “just a movie,” many of the boys realized in their personal adult lives that it was far better to work hard to choose the upward, inclusive way of Ralph, rather than to ever find oneself descending into Jack-ness. A friend of mine has a saying, “I’m going to get as old as I possibly can get.” From what I can tell, he has. I must agree with his sentiment. Of course, the alternative is… well you know. Another friend of mine likes to tell me, “Brother, you’re only as old as you feel.” I am not sure how old feels or if wrinkles are involved. But, I am feeling quite fine, thank you. Just the other day the Gracious Mistress of the Parsonage came in from her workshop, sat down on the couch and said, “Whew, I feel like a hundred.” At the time, I did not know if she was talking about dollars, pounds or years. Being the old fogey that I am, I know there are times when silence is golden and this was one of those golden moments. But, what does a hundred feel like? Is there some special sensation that pulsates through the body when a person reaches that age level? Or, is it the absence of anything pulsating through your body? Just this morning I got up with a sore knee and could hardly walk to the bathroom. I complained about it to my wife, who has no compunction about expressing her opinions, said, “Well, you are older than when you went to bed last night.” I did not know I was aging so rapidly. If this keeps up, I will change from an old fogey into an old geezer before I know it. The difference between an old fogey and an old geezer is, an old fogey walks around in a fog while the old geezer cannot get up from his chair and wheezes a lot. I was musing on the idea that getting old was a lot of trouble with a lot of pain involved. Then I remembered what a lot of trouble and pain it was to be young. As a youngster, I thought many times, “Oh, I can’t wait to get old.” I thought getting older was the panacea for all of my problems. I remember thinking that when I got older nobody would boss me around. I would do whatever I wanted to do whenever I wanted to do it. I could not wait for that time to come. I dreamed of that mystical land. No parents to boss me around; no teachers to tell me what to do and when to do it; no siblings interfering with my plans for the day. What a life I would lead when I got older. I lived each day hoping to get older which, in my thinking, was the door into that area. Just as I was entering that mysterious realm of being my own boss, I got married. Not only that, but several years into that marital bliss came the pitter-patter of little feet in the hallway. I did not figure that getting older would involve so many people in my life. Just going to the bathroom, for example, was a three-day wait. And, guess who is at the bottom of the list? I guess you know you have gotten old when you give up the idyllic idea of being your own boss, doing whatever you want to do, whenever you want to do it. Now that I think of it, it was a lot more painful and a lot more troublesome to be young than it is to be old. In fact, there are some marvelous advantages of getting older. For example, when my wife sends me to the grocery store to get a few things I usually forget something. Now, that I am getting older, I can tell her that I do not remember things as I used to, after all, I’m getting older. Also, when someone invites me to go out and play what they call senior softball, I can always say, “I would love to, but my knees are acting up now that I’m getting older.” This process of getting older has drastically improved my social life. Every joke I hear is as if I am hearing it for the very first time. It is amazing. My wife and I were at a social function not too long ago, and I was having a marvelous time. When we got home, my wife said to me, “You put on a good act tonight.” “What you mean I put on a good act?” “You laughed at every joke tonight as if it was the first time you ever heard it.” I did not have the heart to tell her that it was the first time I heard those jokes. That is what is so marvelous about getting old. You do not have to burden your brain, and all the little gray cells in it, with remembering things. My brain is now free to enjoy the moment. It is wonderful getting older. When I was younger, it would embarrass me if I forgot something. Of course, I blame that on my parents and teachers who tried to pound into my little head that I needed to remember everything. Now that I am older, I do not have that burden. It is good to remember some things. I remembered one of my favorite Bible passages. “Trust in the LORD with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths” (Proverbs 3:5-6 KJV). I will never get too old to trust the Lord with all my heart. The Rev. James L.
