  1. UFO, Area 51, etc. FYOS Lecture 12

  2. More than a half of Americans believe UFO • 2002 October poll • 72 percent of Americans believe the government is holding the truth on UFO • men more than women think such information should be shared with the public • The younger you are, the stronger your belief that the government is withholding information • 1997 CNN/TIME MAGAZINE POLL (June) 
54% believe intelligent life exists beyond earth 
64% believe aliens have contacted humans 
50% believe that aliens have abducted humans 
37% believe that aliens have contacted the US government 
75% believe that a UFO crashed near Roswell 
26% believe that they would be expected to be treated as an enemy 
39% believe that aliens would appear very humanoid 
 • In a 1947 US Gallup Poll 90% of the population who heard of flying saucers believed they were not real.

  3. 1st modern report • June 24, 1947 by a businessman Kenneth Arnold • 9 shiny objects with wings streaking the sky at 2,000 km/h “… they flew erratic like a saucer if you skip it across the water.” • A reporter mistakenly described the objects as “flying saucers”

  4. UFO sightings • about 10,000 sightings are reported a year • It is true that there are unidentified objects being seen in the sky • Some claims from seasoned pilots or astronauts whose credibility is not in question. • Even many astronomers have seen unidentifiable objects in the sky. • Something unidentifiable ≠ alien UFOs • US Air Force started investigation on the UFO phenomenon (largely by Cold War concerns).

  5. In 50s and 60s, experts could identify UFOs into bright stars and planets, aircraft and gliders, rocket launches, balloons, birds, ball lightning, meteors, atmospheric phenomena, and hoax.

  6. Ball lightning • atmospheric electric phenomenon via unknown mechanism. • unlike regular flash lightnings, these ball lightningscan last several seconds with a size in the range of a fist to several meters across. The physicists produce luminous plasma balls above a water surface which have lifetimes of almost half a second and diameters of 10 to 20 centimeters.

  7. Flying Saucer over Damascus, Syria?

  8. Lenticular cloud formation

  11. Lubbock Lights • Aug 1951, three Texas Tech faculty members • 15-20 faint white lights in a formation passing the sky. They estimated the altitude being ~50,000 feet  5 miles per second! • An hour later they saw one more group. • 2 hours later saw a 3rd group. It is impossible to determine the distance, altitude, or the speed of an object in the sky

  12. Venus in Georgia • Fall 1967, police officers at 10+ places reported sighting of UFOs. • Two officers “chased” the “bright-red football shaped light” for 8 miles and could not chase it.  when they returned to their station, it caught up with them! • They watched it ~30min seeing that the UFO changed in color from redorangewhite, climbing in the sky until it resembled “a star”. • The police report sparked a local interest in UFOs. Hundreds of UFO sightings in following weeks.  The tendency (ability) of one report to trigger many others!

  13. Venus and Jupiter in Caspian Sea

  14. UFOs • about 90% of the well-documented UFO cases were explainable as earthly phenomena. • This does not mean that the remaining 10% unexplainable cases are alien spaceships!

  15. Others… • Wild animal mutilation by aliens Chupacabras • Alien abduction • sleep paralysis? occur during REM sleep, for a few minutes after the brain wakes up, our body can be still in sleep paralysis with active vision and feeling. survey says that ~50% of people experience sleep paralysis at some points in their lives.
