//__**BIG BANG**__//
//**__1) About how long ago did the big bang take place?__**// //According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago.// //__**2) What is a black hole?**__// //Black holes are areas of intense gravitational pressure.// //__**3) Does the universe continue to expand?**__// //After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe.// //It continues to expand and cool to this day and we are inside of it.// //__**4) Was there really a big bang?**__// //Yes, The Big Bang theory is an effort to explain what happened at the very beginning of our universe.// //The big bang theory is an effort to explain what happened during and after that moment.//

//__**5) What light elements seem to support the Big Bang Theory?**__// //the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.//

__**Time Keeps On Slippin’**__
__**1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted.**__ CIVIL CALENDAR,It was introduced by Pope Gregory XIII, after whom the calendar was named, by a decree signed on 24 February 1582, a papal bull known by its opening words Inter gravissimas.[4] The reformed calendar was adopted later that year by a handful of countries, with other countries adopting it over the following centuries. __**2) What is a leap year.**__ The Gregorian calendar modifies the Julian calendar's regular cycle of leap years, years exactly divisible by four. __**3) List three other types of calendars used and how they set up their calendar (ex. Lunar).**__ Ice-age hunters in Europe over 20,000 years ago scratched lines and gouged holes in sticks and bones, possibly counting the days between phases of the moon. Five thousand years ago, Sumerians in the Tigris-Euphrates valley in today's Iraq had a calendar that divided the year into 30 day months, divided the day into 12 periods (each corresponding to 2 of our hours), and divided these periods into 30 parts (each like 4 of our minutes). We have no written records of Stonehenge, built over 4000 years ago in England, but its alignments show its purposes apparently included the determination of seasonal or celestial events, such as lunar eclipses, solstices and so on. __**4) What is BC?**__ Before Christ. __**5) What is BCE?**__ Before Common Era. __**6) What is AD?**__ Anno Domini. __**7) What is CE?**__ Common era. __**8) What is MYA?**__ Million years ago. __**9) According to the timeline site how many periods of when are there and list time.**__ 14000 MYA: Big Bang: Formation of the universe 4600 MYA: Formation of the Earth.  543 MYA-490 MYA: Cambrian: Explosion of Life on Earth  290 MYA-248 MYA: Permian: Largest mass extinction  245 MYA- 65 MYA: Mesozoic: Age of Dinosaurs  5 MYA- 2500 BC: Stone age: The human era  70000BC – 8000 BC: Ice age Extinction of large mammals  9000 BC – 4500 BC: Neolithic: First permanent settlements  3200 BC – 1200 BC: Bronze age: Firs Pharaohs  1200 BC – 332 BC : Iron age: Start of the Trojan war  332 BC – 63 BC : Hellenistic Period  63 BC – 476: Roman Period  330 – 1453: Byzantine Period __**10) What is an eon, epoch, era, and age?**__ Geologic time scale. __**11) List three ancient calendars**__ Egyptian calendar, Aztec calendar, Solar calendar. __**12) List two ancient clocks and how they worked.**__ __Sun clocks__: were built as early as 3500 BCE. Their moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon. Obelisks also showed the year's longest and shortest days when the shadow at noon was the shortest or longest of the year. Later, additional markers around the base of the monument would indicate further subdivisions of time. __Water clocks__: Later named clepsydras by the Greeks, who began using them about 325 BCE, these were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom. Other clepsydras were cylindrical or bowl-shaped containers designed to slowly fill with water coming in at a constant rate. Markings on the inside surfaces measured the passage of "hours" as the water level reached them. __**13) What was a revolution of timekeeping?**__ In Europe during most of the Middle Ages (roughly 500 CE to 1500 CE), technological advancement virtually ceased. Sundial styles evolved, but didn't move far from ancient Egyptian principles. __**14) What allows for standard more accurate clocks?**__ In 1656, Christian Huygens, a Dutch scientist, made the first pendulum clock, regulated by a mechanism with a "natural" period of oscillation. (Galileo Galilei is credited with inventing the pendulum-clock concept, and he studied the motion of the pendulum as early as 1582. He even sketched out a design for a pendulum clock, but he never actually constructed one before his death in 1642.) Huygens' early pendulum clock had an error of less than 1 minute a day, the first time such accuracy had been achieved. His later refinements reduced his clock's error to less than 10 seconds a day. __**15) What are time zones?**__ Time zones are based on Greenwich Mean Time (GMT), the mean solar time at longitude 0° (the prime meridian). __**16) What is the prime meridian?**__ Is the meridian (line of longitudel) at which the longitude is defined to be 0°. __**17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii?**__ --toronto:11 am --london:11 am --moscow:6 pm --tokyo:12 midnight --hawaii:5 am __**18) What is Daylight Saving Time? Do we use this in Saskatchewan?**__ Daylight saving time was extending one hour and gain extra time. No, we don't use this in Saskatchewan. __**19) Is there a year zero?**__ NO. __**20) Are we starting a new decade in 2010 or 2011?**__ Yes. __**21) What is linear time?**__ A time base that makes the electron beam of a cathode-ray tube move at a constant speed along the horizontal time scale. __**22) What is cyclical time?**__ Moving in cycles. __**Bonus Question**__ In What Steve Miller song does time ‘keep slippin’ into the future’? __Fly Like An Eagle__.
