Big Bang Theory Assignment

 * 1) About how long ago did the big bang take place?**

The big bang took place 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?**

Yes. It was previously very small and hot, but has now expanded to the size and temperature of the universe today.


 * 4) Was there really a big bang?**

Scientists say no. Rather than one big explosion, the universe constantly expands.


 * 5) What light elements seem to support the Big Bang Theory?**

Most people are sure that the universe had a beginning. Also, galaxies appear to be moving away from us at proportionate speeds; this supports the idea of the universe being compacted at one time and that it is constantly expanding. In addition to that, if the universe was as hot as researchers say it was, we can still find some remnants of this heat. Last but not least, 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.
 * The Gregorian Calendar ( as known as the Western Or Christian Calender ) is the one that is used by most of the world. Pope Gregory XIII made it and it is accepted because the Julian calendar suggests that the time between vertical equinoxes is 365.25 days; when it really is approximately 11 minutes less.

2) What is a leap year?
 * "Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100; the centurial years that are exactly divisible by 400 are still leap years. For example, the year 1900 is not a leap year; the year 2000 is a leap year."

3) List three other types of calendars used and how they set up their calendar (ex. Lunar).


 * 360 day calendar - It consists of 360 days, 12 months in a year, and 30 days in a month.
 * Irish Calendar -"The **Irish calendar** is [|a pre-Christian Celtic system of timekeeping] used during [|Ireland's Gaelic era] to define the beginning and length of the day, the week, the month, the seasons, quarter days, and festivals."
 * Chinese Calendar - "The months are lunar months. This means the first day of each month beginning at //midnight// is the day of the astronomical [|dark moon"]

4) What is BC?  · It is Before Christ.

5) What is BCE?  · It is Before Common Era.   6) What is AD? · It means Anno Domini. It could also mean Year Of Our Lord which is in reference to Christ's Birth.

7) What is CE?  · CE is 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.  · According to the site, there are 21 periods.     -Formation of the earth – 4600 MYA     Cambrian: Explosion of life on the earth – 543-490 MYA     Permian: Largest mass extinction – 290-248 MYA     Mesozoic: Age of the dinosaurs – 245-65 MYA     Stone Age: Human era – 5 MYA – 2500 BC     Ice Age: Extinction of large mammals – 70000-8000 BC     Neolithic: First Permanent Settlements – 9000-4500 BC     Bronze Age: First Pharaohs – 3200-1200 BC     Iron Age: Start of the Trojan War – 1200-332 BC     Hellenistic Period – 332-63 BC     Roman Period – 63 BC – 476     Byzantine Period – 330-1453     Middle Ages – 476-1350     Renaissance – 1350-1600     Reformation – 1500-1600     Enlightenment – 1600-1800     Industrial Revolution – 1750-1900     20th Century – 1900-2000     21st Century - 2099  Future – 2009

10) What is an eon, epoch, era, and age?  · Eon: The major division of the geologic time scale.   · Era: longer than a period but shorter than an eon.   · Epoch: A subdivision of geologic time that is longer than an age but shorter than a period.   · Age: a period of the history of the [|earth] distinguished by some special feature.

11) List three ancient calendars.The Egyptian Calendar
 * The Sumerians Calendar
 * The Babylonians' Calendar

12) List two ancient clocks and how they worked.
 * The Sun Clock "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."
 * The Water Clock - "these were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom."

13) What was a revolution of timekeeping?
 * In Europe during most of the Middle Ages technological advancement virtually ceased.

14) What allows for standard more accurate clocks?
 * We have no evidence or record of the working models proceeding these public clocks which were wight-driven and regulated by a verge- and foliot escapement.

15) What are time zones?  · "A time zone is a region on Earth more or less bounded by lines of longitude, that has a uniform, legally mandated standard time, usually referred to as the local time."

16) What is the prime meridian?  · "The Prime Meridian is the [|meridian] (line of [|longitude]) 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 - 11:00 AM  London - 4:00PM  Moscow - 7:00 PM  Tokyo - 1:00 AM  Hawaii - 6:00 AM  18) What is Daylight Saving Time? Do we use this in Saskatchewan? · "During late winter we move our clocks one hour ahead and "lose" an hour during the night and each fall we move our clocks back one hour and "gain" an extra hour." No, we do not use it in Saskatchewan.

19) Is there a year zero? ""Year zero" does not exist in the widely used [|Gregorian calendar] or in its predecessor, the [|Julian calendar]. Under those systems, the year [|1 BC] is followed by [|AD 1]. However, there is a year zero in [|astronomical year numbering] (where it coincides with the Julian year 1 BC) and in [|ISO 8601:2004] (where it coincides with the Gregorian year 1 BC) as well as in all [|Buddhist] and [|Hindu calendars].”  20) Are we starting a new decade in 2010 or 2011?   · "We never had a 'year 0', so 2011 is the start of a new decade.

21) What is linear time?  · "Linear time is a concept where by time is seen sequentially, as a series of events that are leading toward something: beginning, and an end. In Newtonain theory it is something absolute in reality, regardless of human perception. "

22) What is cyclical time?  · "Moving in cycles"

Bonus Question: · Fly Like An Eagle.
