Time

__** The big bang theory. **__ 1.37 billion years ago. Black holes are areas of intense gravitational pressure. Yes, the weather is always changing because it use to be very small and really hot, but now it have expanded and it is cooling down. Experters are saying that there wasn't an explosion. Hydrogen and Helium Found In the Observable Universe are the thoughts that support The Big Bang model of the origins.
 * 1. About how long ago did the big bang take place?**
 * 2.What is a black hole?**
 * 3.Does the universe continue to expand?**
 * 4.Was there really a big bang?**
 * 5.What light elements seem to support the big bang theory?**

__** Times keeps **** on **** slipping. **__ **1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted.** It was introduced by Pope Gregory XII **2) What is a leap year?** All the years that are divisible by four is a leap year, except for years that are exactly divisible by 100. **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. ? ** 4) What is BC ﻿? ** Its before christ. **5) What is BCE?** It’s before common era **6) What is AD?** It’s anno domini or year of our lord referring of the year of christ's birth. **7) What is CE?** It means common era. **8) What is MYA?** It means million years ago. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**9) According to the timeline site how many periods of when are there and list time.** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Big Bang• Bronze Age • Byzantine• Cambrian • Enlightenment • First Settlements • Formation Earth • Hellenistic Age • Ice Age • Industrial Age• Iron Age • Mesozoic• Middle Ages • Permian • Reformation • Renaissance • Roman Age • Stone Age • Future <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**10) What is an eon, epoch, era, and age?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Eon: the longest division of geological time <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Epoch: a period marked by distinctive character or reckoned from a fixed point or event <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Era: period marked by distinctive character or reckoned from a fixed point or event <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Age: how long something has existed; "it was replaced because of its age" <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**11) List three ancient calendar**  - The earliest Egyptian calendar 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. -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. -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="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**12) List two ancient clocks and how they worked.** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">-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: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">-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="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**13) What was a revolution of timekeeping?**  In Europe during most of the Middle Ages technological advancement virtually ceased .  <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**14) What allows for standard more accurate clocks?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">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="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**15) What are time zones?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">A time zone is a region of the earth that has uniform standard time, usually referred to as the local time. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**16) What is the prime meridian?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0°.17) <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**17) If it’s 10:00 AM in Regina, what time is it in Toronto?

No I don’t think we use Daylight Saving Time in Regina. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**19) Is there a year zero?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">No There Is Not A Year Zero <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**20) Are we starting a new decade in 2010 or 2011?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">In 2011 <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">**21) What is linear time?** <span style="color: #e36c0a; font-family: 'Comic Sans MS'; font-size: 10pt; line-height: 115%; margin: 0in 0in 10pt;">Linear time is a concept whereby time is seen sequentially, as a series of events that are leading toward something: beginning, and an end.
