THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE (SETI)

SETI is an international group of scientists and lay people who scan the heavens for signs of life on other planets. See SETI Institute On Line and SERENDIP at the University of California. An innovative program, SETI@home, uses the Internet to send packets of recorded interstellar radio signals to home and office computers. Any computer user can participate by running a free program that analyzes the packets of radio signals for transmissions from civilizations on other planets. The SETI@home program operates only when the participant's computer is not being used for other tasks. The results are sent to SETI when the computer is logged onto the Internet. SETI then sends back a new packet of interstellar radio signals for analysis. (The radio signals are gathered by the Arecibo Observatory in Puerto Rico which is the scene for the early portion of the movie.) The SETI@home program has an attractive screen saver which provides a visual representation of the analysis as it occurs. SETI@home allows any person with an up-to-date computer to contribute to SETI with a minimum of inconvenience.

WORM HOLES

When Carl Sagan, the author of the novel Contact, was looking for a way to transport his heroine through space-time, he came up with the idea of going through a worm hole. The concept of a worm hole in space-time had been around for decades. If a black hole is rotating and joins up with a "white" hole, it would be possible for matter to be drawn into the mouth of the black hole and to pop out through the white hole. The result is a worm hole. However, people could not pass through a worm hole because they would be crushed by the tremendous pressures in the black hole. Sagan asked Cal Tech theoretical physicist Kip Thorne if it was possible to design a method of travel that would protect a person in transit through a worm hole. Intrigued by the problem, Thorne and his students came up with the idea of lining the side of the worm hole with an exotic form of matter that had anti-gravitational properties. A number of papers in theoretical physics were published on this question. For more on Sagan, Kip Thorne and worm holes, see Traversable Worm Holes and Wormholes: Searching for a Subway to the Stars. For a diagram of how a worm hole could take a person to Vega in a few hours, see Marcelo Maidana's Web Site. For photographs, see Spectacular views of black holes at the centers of galaxies. What happens when a black hole is linked to a star? See Diagram of Possible Relationships.

Good science fiction often predicts coming breakthroughs in science and technology. (An excellent example is Jules Verne's 19th Century prediction of Captain Nemo's atomic powered submarine in 20,000 Leagues Under the Sea). In this case, Sagan's inquiry led to a boomlet of theoretical papers on using worm holes as an intergalactic transportation system. The speculation never went anywhere and some physicists saw the effort as a waste of time.

PRIME NUMBERS

Any integer greater than one is called a prime number if it can only be divided by one and by the number itself. Integers that are not prime are called composite numbers. The number 1 is considered neither prime nor composite but in a class of its own. When composite numbers are factored completely, each of the factors will be prime numbers. For example, the number 78, a composite number, can be factored into 2 X 39, while 39 can be broken down into 3 X 13. Thus the prime factors of 78 are 2, 3 and 13. This is an example of the application of the Fundamental Theorem of Arithmetic which states that "Every integer can be written as a product of primes in an essentially unique way."

The prime numbers between 1 and 100 are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97
The mathematicians of the Pythagorean school (500 B.C.E. to 300 B.C.E.) were interested in numbers for their mystical and numerological properties. They understood the idea of primality and were also interested in perfect and amicable numbers. A perfect number is one whose divisors sum to the number itself. e.g. the number 6 has divisors 1, 2 and 3. It is classified as a perfect number because 1 + 2 + 3 also equal 6. The number 28, with divisors of 1, 2, 4, 7 and 14 is also a perfect number, i.e., 1 + 2 + 4 + 7 + 14 = 28. Amicable numbers occur when the divisors of one number sum to the other and vice versa. The numbers 220 and 284 are amicable. There are many good web sites explaining prime numbers: They include The Math Forum, The Prime Pages and Prime Numbers.

OCCAM'S RAZOR

Occam's Razor is a principle of logic and philosophy that is perhaps most appropriately stated as "when you have two competing theories which make exactly the same prediction, the one that is simpler is the better." It was popularized and extensively applied by a 14th century logician and Franciscan friar named William of Occam (or Ockham)(1284-1347). Occam's Razor describes only what is more likely. It is always subject to confirmation by experimentation. It only applies when the two competing theories make exactly the same prediction.

An example of the proper use of Occam's Razor relates to the crop circles that appeared in England in the early 1970s. At first, circles, and then more intricate designs appeared as depressed grass or plants in fields in England. There was much speculation that they were caused by aliens coming to Earth in space ships. Articles and books were written about them. Quasi-scientific missions set out to discover the aliens in the act. Occam's Razor told the skeptics that the simplest hypothesis (i.e., the designs were man-made) was the most likely. The alternative, aliens mounting an expedition from a far away stellar system to Earth, arriving, making the designs and then disappearing, all undetected, was more complicated. In fact, after several years, two English pranksters revealed that they had cooked up the whole thing at the local pub over two pints of Guinness. See Carl Sagan's article Crop Circles and Aliens: What's The Evidence? Parade Magazine (The Baltimore Sun); Sunday, December 3, 1995. pp. 10-12, 17.

THE DRAKE EQUATION

What are the specific factors that play a role in the development of intelligent civilizations on planets? While it provides only very rough estimations of the probability of intelligent life in space, the Drake Equation is generally accepted and used by the scientific community to examine this question. The equation is: N = R* x fp x ne x fl x fi x fc x L . Where,
N = The number of communicative civilizations. (The number of civilizations in the Milky Way Galaxy whose radio emissions are detectable.)

R* = The rate of formation of suitable stars. (The rate of formation of stars with a large enough "habitable zone" and long enough lifetime to be suitable for the development of intelligent life.)

fp = The fraction of those stars with planets. (The fraction of Sun-like stars with planets is currently unknown, but evidence indicates that planetary systems may be common for stars like the Sun.)

ne = The number of "earths" per planetary system. (All stars have a habitable zone where a planet would be able to maintain a temperature that would allow liquid water. A planet in the habitable zone could have the basic conditions for life as we know it.)

fl = The fraction of those planets where life develops. (Although a planet orbits in the habitable zone of a suitable star, other factors are necessary for life to arise. Thus, only a fraction of suitable planets will actually develop life.)

fi = The fraction of life sites where intelligence develops. (Life on Earth began over 3.5 billion years ago. It was not until the last ten thousand years that intelligent life developed. On other life-bearing planets it may happen faster, it may take longer, or it may not develop at all.)

fc = The fraction of planets where technology develops. (The fraction of planets with intelligent life that develop technological civilizations, i.e., technology that sends detectable signs of their existence into space.)

L = The "Lifetime" of communicating civilizations. (The length of time such civilizations sends detectable signals into space.)

Interesting Notes: There are several SETI projects. Project Phoenix searches for signals from approximately 1,000 nearby sun-like stars. The SETI project described in the film resembles Project Phoenix. The director of Project Phoenix was, at the time the novel was written, a woman. One of its project directors was blind. However, the characters in the film are creations of the novelist and, so far as we know, they are not otherwise patterned on these individuals. For more comparisons between reality and the film, see SETI Institute on Contact.

After Ellie Arroway discovers the message from the aliens, the film shows President Clinton giving a press conference. This footage was taken from an incident when a Martian meteorite was discovered to have possible evidence of life. Also note that Warner Brothers, the film's producer, and CNN were both owned by the same conglomerate, Time Warner.

Discussion Questions:

1. See Questions Suitable for Any Film.

2. Scientists have found evidence that the Earth and the moon suffered a cataclysmic bombardment of asteroids at about the time life began on Earth. Is this the origin of life on Earth?

3. If it were shown that human beings were not the only intelligent beings in the universe, how would that affect your religious beliefs? Suggested Response: There is no correct answer to this question. We suspect most people would say that their beliefs have a large enough scope to include aliens.

4. Do you believe that the existence or non-existence of God depends upon whether extraterrestrial life exists? Suggested Response: See suggested Response to preceding question.

5. What would it mean to you if it were discovered that there were civilizations of intelligent beings on other planets? Suggested Response: There is no one right answer. Some people feel that mankind, as the only intelligent species we know, are a lonely race. They would feel less lonely if there were intelligent aliens. Some might find their religious faith to be confirmed by the existence of aliens while others would view aliens as a challenge to their religious beliefs.

6. How would you answer Palmer Joss' question: " ... [A]re we happier as a human race? Is the world fundamentally a better place because of science and technology? We shop at home, we surf the web, but at the same time, we feel emptier, lonelier, and more cut off from each other than at any other time in history.... Maybe it's because we're looking for the meaning. Well, what is the meaning? We have mindless jobs. We take frantic vacations, deficit finance trips to the mall to buy more things that we feel are gonna fill these holes in our lives. Is it any wonder that we've lost our sense of direction?" Suggested Response: The basic answer is that science cannot buy happiness and cannot provide meaning for our lives. To the extent that applied medical science improves our health and applied agricultural science allows hungry people to eat, happiness is increased. But those of us who live longer, more active, and less hungry lives, still must face the question that the Joss character poses. The answer is the same no matter how long we live or how much food is available.

7. Palmer Joss also said: "The one thing that people are most hungry for, meaning, is the one thing that science hasn't been able to give them." Do you agree or disagree? Explain your reasoning. Suggested Response: Science cannot provide meaning for our lives, that is the role of religious or philosophical belief. Science is a method of finding out about the physical universe. For some scientists, it provides a quest, a passion, a profession and a life's work, in the same way that any job can be used as the center of a person's life. But that is not the type of "meaning" that the Joss character is asking about.

8. Can anyone,using the scientific method, prove or disprove the existence of a supreme being, the truth of a belief about the meaning of life, or what is the proper way to live? Is this even a reasonable question to ask a scientist? Suggested Response: The answer to both questions is "No." Science is a method of evaluating theories that explain the physical and natural world. This extends to the way that people and animals act. It does not tell us about a supreme being because eventually, as one analyzes the natural world, there will be the origin of some energy or of matter that is not known. The queries outlined in the first sentence of the question are beyond the scope of science.

9. The Alien told Ellie that: "See, in all our searching, the only thing we found that makes the emptiness bearable is each other." Do you agree or disagree?

10. In the film, Ellie's experience is confirmed by the 18 minutes of static on the tape. What is the message of this development?

11. Galileo said that "Mathematics is the alphabet with which God has written the universe." How does this statement apply to the issues about science and religion brought out by this film? Suggested Response: This statement embodied Galileo's personal reconciliation of religion and science. To Galileo, his scientific discoveries did not challenge the concept that God was the creative force behind the universe. His scientific discoveries were simply an exploration and description of God's handiwork.

12. Are belief in the discoveries of science and belief in a supreme being incompatible? Suggested Response: See discussion in Helpful Background Section.

13. After Ellie's father died, the priest told her "We aren't always meant to know the reasons why things happen. It's God's will." Do you agree or disagree with this statement?

14. Do you think that 95% of the Earth's population believe in a supreme being?

15. Do you agree that if we were to send a representative from Earth to another planet, we should only send a person who states that he or she believes in a supreme being?

16. At the end of the film Ellie Arroway says:
I had an experience I can't prove, I can't even explain it, but everything that I know as a human being, everything that I am, tells me that it was real. I was part of something wonderful, something that changed me forever; a vision of the universe that tells us undeniably how tiny, and insignificant, and how rare and precious we all are. A vision that tells us we belong to something that is greater than ourselves. That we are not, that none of us are alone. I wish I could share that. I wish that everyone, if even for one moment, could feel that awe, and humility, and the hope, but ... that continues to be my wish.
What other type of person would talk like this? What does this passage mean to you? Would the Ellie Arroway at the beginning of the film have said something like this?

17. Is it a proper use of science to prove a preconceived belief about an aspect or a process of the physical world?
