  3. MAYOR IMPORTANCE • ASTRONOMY – life on other planets, planet Winter, space travel • PHYSYCS – time jumps, twin paradox • BIOLOGY – androgyny, hibernation

  4. LIFE ON OTHER PLANETS • MARS • OUR SOLAR SYSTEM (Sun, 9 planets, Moons) • MILKY WAY (200 – 400 billion stars) • THE OBSERVABLE UNIVERSE (more than a 100 billion galaxies)

  5. ALPHA CENTAURI • Closest solar system (4.35 light years) • Alpha Centauri A , Alpha Centauri B, Alpha Centauri C = Proxima • A – 5 tests, B – 4 tests, C – 0 tests

  6. TESTS FOR LIFE ON OTHER PLANETS • The star’s stability • The spectral type of the star (G-type) • Stable conditions • Star’s age • Enough heavy elements (carbon, nitrogen, oxygen, iron) • Planets!!!

  7. SPACE TRAVEL AND HIBERNATION • Earth  Alpha Centauri = 18000 years (4200 years)

  8. HIBERNATION • Hibernation used by animals (bats, squirrels, hedgehogs, bears,etc.; saves energy, lowers bodytemp., slows down breathing andmetabolism) • Coincidental hibernation (snow, cold water, freezing temp.) • “Real” hibernation (air filled with hydrogen sulphide vs cryonics)

  9. TWIN PARADOX, TIME JUMPS

  10. WINTER/GETHEN Period of rotation = 23.08 hours 1 year = 364 days 1 month = 26 days 14 months Adjustement – in 200 years 1 day = 10 hours Moon – the same face EARTH Period of rotation = 23.9345 hours 1 year = 365.25 days 1 month = 30/31 days 12 months Adjustement – in 4 years 1 day = 24 hours Moon – the same face PLANET WINTER vs PLANET EARTH

  11. GETHENIANS • sexual cycle: 26 – 28 days • 21 – 22 days sexualy inactive, 18th day hormonal changes, 22nd or 23rd day – kemmer • 1st phase of kemmer – androgyns, 2nd phase of kemmer – changing into man or woman, 3rd phase of kemmer 2-5 days • pregnancy 8.4 months, lactation period 6-8 months

  12. ANDROGYNY / HERMAPHRODISM THREE BILOGICAL PHENOMENA

  13. MALE and FEMALE • HAMLET – fish (both sexes; a pair takes turns in mating) • EARTHWORMS (a single sex at a time; protective mechanisms against self fertilization) • BANANA SLUGS (self fertilization is often practiced)

  14. MALEFEMALE, FEMALEMALE • CLOWNFISH (harems, male  female) • WRASSES – reef fish (females  grow up  males OR males and females  supermale)

  15. ABNORMALITIES IN PRIMATES • the primate is either genetically male or female, but has external organs resembling those of the opposite sex • 1% of mammals • humans – altered shortly after birth • neither set of organs is functional

  16. LIGHT IS THE LEFT HAND OF DARKNESS AND DARKNESS THE RIGHT HAND OF LIGHT. TWO ARE ONE, LIFE AND DEATH, LYING TOGETHER LIKE LOVERS IN KEMMER, LIKE HANDS JOINED TOGETHER, LIKE THE END AND THE WAY.
