Search for Extraterrestrial Life: Scientific Questions and Goals Group 2: Christine Cho, Han Lin Rong, Jessica Williams Scientific Questions ? Who is out there? ? What are they like and what are their fundamental values and priorities? ? What do they know about us? ? What sorts of detectable communications might they be using? Scientific Questions Continued ? What role will they play in our long-term future? ? How can we benefit from this interaction in terms of solving some of our present issues such as cancer and global warming? ? What sort of information would be garnered by SEL scientists? Scientific Goals Discover the Nature of Life throughout the Universe. Help Develop Scientific Theory. Provide Solutions to Earth’s Future Problems. Get Philosophical Answers. Discovering the Nature of Life Understand the requirements for life to exist. Distinguish between what biological components are inherent to all life vs. what we have developed due to the Earth’s environment. Study the extraterrestrials biochemistry, sensory organs, and physiology. Help Develop Scientific Theory Help determine if universe expansion is slowing or it will recycle itself. Develop potential technologies to travel faster than light. Synthesize new protein enzymes with desirable characteristics. Better estimate Drake Equation coefficients. Better understand the nature of climate on terrestrial planets. Solving Earth’s Future Problems Existing life forms may provide cues to longevity. Discover alternative places to live. Solve ecological and pollution problems. Provide insights into unknown possibilities. Getting Philosophical Answers Are we alone? Accepting the existence of extraterrestrial life. Finding new art forms that would enrich life. References Tough, A. "Positive Consequences of SETI before Detection." Acta Astronautica 42.10-12 (1998): 745-48. Print.
