• Don Yeomans is a planetary scientist at NASA’s Jet Propulsion Laboratory. He is the manager of the Near-Earth Object Program, whose safety-first mission is to “coordinate NASA-sponsored efforts to detect, track and characterize potentially hazardous asteroids and comets that could approach the Earth.”

    In this three-minute video, Yeomans easily—and scientifically—debunks a host of rumors that pinpoint December 21, 2012, as the “end of the world.”

    Outline
    The rumors Yeomans debunks are:

    • “end of the Mayan calendar” (start-0:30)
    • collision with Niburu, a near-Earth object (0:30-1:19)
    • atmospheric fallout from solar storms (1:19-1:50)
    • tidal effects of planetary alignments (1:50-2:25)
    • shifting magnetic poles (2:25-3:09)

    Finally, Yeomans reminds us that “extraordinary claims require extraordinary evidence.” (3:09-3:30)

    Teaching Strategies
    Have students watch the video, and discuss general or specific “doomsday” rumors. These are all scenarios that purport to have a basis in science and history. These rumors can be researched using the scientific method. Note that Yeomans does not address any faith-based “end times” predictions.

    • Ask students what information they’ve heard about any of the “doomsday” scenarios Yeomans addresses in the video.
      • What have they heard?
      • Where, or from whom, did they get that information? Do they think these sources are reliable? Why or why not?
      • Do students trust what Yeomans, a NASA scientist, says in the video? Why or why not?
    • There is an entire branch of study, eschatology, that focuses on the “end of the world.” Ask students why they think people are so fascinated by doomsday or end-of-the-world scenarios.
      • Do students think there is a simple, widespread lack of scientific understanding?
      • Having a definite date for doomsday can eliminate a lot of responsibility and fears about the future. Some psychologists say that predicting the end of the world is a response to people feeling they have little control over their lives. Ask students what pressures could contribute to people feeling so helpless. Personal choices? Illness? Environmental fears? Economic or political injustice?
    • Some people mock those who predict a date for the end of the world. Do students think it is funny to laugh or make fun of something so serious? Why?
