The Big Bang Theory Took Place About 13.7 Years Ago. A Black Hole Is Areas Of Intense Gravitational Pressure. Yes, The Universe Use To Be Very very Small And Hot. Now It Has Cooled Down And Expanded To The Size And Temperature It Is Now. Experts say that it wasn't an explosion; there was and still is an expansion on the universe. Hydrogen and Helium Found In the Observable Universe are Thought To Support The Big Bang Model Of The 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 is the most internationaly accepted calendar. It was introduced by Pope Gregory XII

 2) What is a leap year? Leap year is a year that contains 366 days, with February 29 as an additional day: occurring in years whose last two digits are evenly divisible by four, except for centenary years not divisible by 400.

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

1. The Catholic Church maintained a tabular lunar calendar, which was primarily to calculate the date of Easter, and the lunar calendar required reform as well.

2. A perpetual lunar calendar was created, in the sense that 30 different arrangements (lines in the expanded table of epacts) for lunar months were created.

3. Lunisolar calendars these calendars aim to be both solar calendars and lunar calendars, but are more successful in tracking the seasonal cycle than the lunar cycle.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">Epoch: a period marked by distinctive character or reckoned from a fixed point or event <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">Era: period marked by distinctive character or reckoned from a fixed point or event <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">Age: how long something has existed; "it was replaced because of its age"

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 11) List three ancient calendars

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">-The earliest Egyptian calendar [<span class="wiki_link_ext">Ref. ] was based on the moon's cycles, but later the Egyptians realized that the "Dog Star" in Canis Major, which we call Sirius, rose next to the sun every 365 days, about when the annual inundation of the Nile began. <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> -Celestial bodies — the Sun, Moon, planets, and stars — have provided us a reference for measuring the passage of time throughout our existence. Ancient civilizations relied upon the apparent motion of these bodies through the sky to determine seasons, months, and years. <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">-The Babylonians (in today's Iraq) used a year of 12 alternating 29 day and 30 day lunar months, giving a 354 day year. In contrast, the Mayans of Central America relied not only on the Sun and Moon, but also the planet Venus, to establish 260 day and 365 day calendars.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 12) List two ancient clocks and how they worked.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> -Sun Clocks- Moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon.Water Clocks these were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom. <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">-Water clocks- 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.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 13) What was a revolution of timekeeping? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">In Europe during most of the Middle Ages technological advancement virtually ceased.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 14) What allows for standard more accurate clocks? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">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.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 15) What are time zones? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">A time zone is a region of the earth that has uniform standard time, usually referred to as the local time. <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 16) What is the prime meridian? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">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? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> Toronto: 11:00 AM <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> London: 4:00 PM <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> Moscow: 7:00PM <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> Tokyo: 1:00AM <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> Hawaii: 6:00AM

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 18) What is Daylight Saving Time? Do we use this in Saskatchewan? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;">The change to Daylight Saving Time allows us to use less energy in lighting our homes by taking advantage of the longer and later daylight hours. No I don’t think we use Daylight Saving Time in Regina.

<span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> 19) Is there a year zero? <span style="color: #d31515; font-family: 'Comic Sans MS',cursive;"> No There Is Not A Year Zero.
