Cosmologists have observed stars at all stages of development and decline and can calculate a star’s life cycle based on features like size, heat, and light. As stars age, for instance, they begin to cool and radiate less light. Occasionally, however, a younger star is observed to dim for unknown reasons, as if it is cooling more rapidly than expected.

“There are no theories that explain it,” Chudnovsky said. “So maybe it’s a very complicated process related to the function of a civilization inside the star.”

If a star harbored a nuclear civilization within it, he explained, the energy used to sustain that civilization would cause the star to cool and dim faster—in effect speeding up the aging process. And, at some point, the star would no longer produce enough energy to sustain this form of life.

Food has had varying degrees of significance. Some subjects have spent excessive amounts of time eating, nibbling, or counting food; others have become very angry with the food or very fond of it. Here again, evidence is strong that food in a situation of stress may be used as a tool to obtain personal satisfactions.

Palatability and acceptability of food in many instances are contrary to that on the ground or in the air; e.g., brownies have enjoyed only a fair degree of acceptability whereas ordinarily they are highly acceptable; canned orange juice usually rates low in acceptability; in isolation it has moderate to high acceptability. Data also indicate that the ability to discriminate one food from another within the same food group is impaired. All meats taste alike. Subjects are unable to distinguish one canned fruit from another. White, whole wheat, and rye breads used in sandwiches are similar in taste. Thus it is quite apparent that removal of the visual cues ordinarily associated with eating interferes with the taste and enjoyment of food and therefore the acceptability of food.

STRUCTURAL ENGINEER WANTS TO CHANGE EARTH'S ORBIT

By Robert E. Sweet

SEATTLE (UPI) — William E. Peterson wants to erect what amounts to a giant atomic water pistol in the Mojave Desert, shoot it off and change the orbit of the earth.

Or, as Peterson himself once put it in an edition of a local Rotary Club bulletin which he edits: "Some weirdo hereabouts is campaigning for a project to fly the earth."

Peterson is a 40-year-old structural engineer who works mainly on dams and bridges. He has a sense of humor and can understand why some people might think he's a crackpot. But he is dead serious about his "earth sailing" project," which he has tried to sell to everyone from President Nixon to the Sierra Club to private foundations.

PLAN DETAILED

Peterson's plan is to build a nuclear cannon, a mile in diameter at the base, tapering off to a narrow nozzle on top. With an atomic blast that he estimates would be equal to about one million tons of TNT he would force a piston mechanism to shoot sea water out the top of the cannon at terrific speed.

He figures about 10 per cent of the water vapor would escape earth's gravity and the spray would nudge the planet's orbit in the same way jets propel a spacecraft.

The water that remained in the atmosphere, Peterson said in an interview, would act like a "giant sprinkler system" and create rain to water the Mojave Desert.

CITES PREDICTIONS

A new orbit would improve the world's climate, ease pollution problems and "put some life into Death Valley," he said.

"Some reputable scientists say we're in for another ice age in the year 2000," Peterson said, in an interview, noting that others predict all sorts of ecological disasters on the horizon.

"So some day — and maybe not too far in the future — we're going to have to know how to control the orbit to maintain at least the quality of life we know now.

"If we can't do it this way sailing "Our Great Ship Earth," how are we going to do it?"

Peterson said other potential benefits of his proposal include: — Turning the globe into a giant spacecraft and flying it to another sun when our sun burns out, which scientists estimate will be in about 5 billion years.

— Applying the same technology to other planets to bring them closer to the sun for more living space for earthlings.

— Replacing dams with sea water cannons for the sake of electrical power.

— Desalinating sea water.

EASE NATIONALISM

— Easing the excesses of nationalism by fostering a sense of international cooperation in working on the project.

Peterson said the cannon would not necessarily have to be used to alter the earth's orbit. A smaller blast of water would be just a rainmaker and the water that did not leave the structure could drive power pistons to supply electric energy. Or, a nozzle at the top could be directed in such a way as to squelch forest fires.

His plan has been a personal project with Peterson for 13 years, but only in the last few years has he begun promoting it. Among those to whom he has divulged his plan are: President Nixon, the National Aeronautics and Space Administration (NASA), the U.S. Department of Commerce, the Atomic Energy Commission, the Sierra Club, Sen. Henry Jackson, D-Wash., Washington Gov. Dan Evans, and a few private foundations.

REJECTED BY NASA

NASA rejected the plan because its political and ecological implications were beyond the scope of the agency. H. Dale Grubb, NASA's assistant administator for legislative affairs, wrote Peterson:

"It would be presumptuous and inappropriate for one nation or an agency of one nation to speculate on the accomplishment of such a project."

Brock Evans, a spokesman for the conservation-dedicated Sierra Club, replied: "Death Valley, as you know, is a national monument at the present time. Our viewpoint is that we don't always need to make the desert bloom."

Donald F. Moore, an assistant administrator of the U.S. Department of Commerce, Environmental and Science Services Administration, wrote Peterson:

"The President has asked me to review the proposal ... and give you my comments.

"Your idea of changing the orbit of the earth as a means of controlling climate and distribution of rainfall is most intriguing and certainly represents highly creative thinking on your part.

ELASTIC MEDIUM

"Experience has shown, however, that the atmosphere is a very elastic medium, and thus instead of blowing out into space like the exhaust from a rocket, it absorbs the energy and momentum from a nuclear blast and eventually returns it to the earth so that no actual motion of the earth takes place."

Peterson answered these doubts saying: "actually it would be impossible to draw this conclusion since no one has thought of the type of device I have proposed."

He believes his proposal "warrants a feasibility study," even if admittedly it is a "real futuristic idea."

"I don't feel the (federal officials) gave it a fair shake. They just discounted the ideas and did not by any means prove they wouldn't work."

Peterson said he is gaining support locally and would attempt to win voter approval by going from state to state, campaigning.

And, he added, at least his children are convinced the plan would work — they call him "Earth Pilot No. 1."
