The Big Bang Theory 1. About how long ago did the Big Bang take place? The Big Bang took place about 13.7 billion years ago.
2. What is a black hole? A black hole is an area of intense gravitational pressure.
3. Does the universe continue to expand? The universe does continue to expand. The theory says that the universe began as an infinitesimal singularity that expanded and cooled and to this day it continues to do so.
4. Was there really a big bang? There was really no explosion but rather an expansion which continues to grow.
5. What light elements seem to support the Big Bang Theory? Elements that support the Big Bang Theory are Hydrogen and Helium.
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 Georgian Calender, also known as the Western Calender or Christian Calender, is the mostly used calender. It was created by Pope Gregory Xlll on Feb. 25, 1582 and was accepted because the previous Julian Calendar was incorrect.
2) What is a leap year? A leap year is every 4 years. It is a year with one extra day.
3) List three other types of calendars used and how they set up their calendar (ex. Lunar). Three other types of calendars used are the Aztec calendar clock, the lunar, and the stonehenge.
4) What is BC? BC means Before Christ.
5) What is BCE? BCE means before common era.
6) What is AD? AD means Anno Domini, which refers to the year Christ was born.
7) What is CE? CE means common era.
8) What is MYA? MYA means million years ago.
9) According to the timeline site how many periods of when are there and list time. The big bang- 14000 MYA The formation of Earth- 4600 MYA Cambrian- 543 MYA- 490 MYA Permian- 290 MYA- 248 MYA Mesozoic- 245 MYA- 65 MYA Stone Age- 5 MYA- 2500 BC Ice Age- 70000 BC- 8000 BC Neolithic- 9000 BC- 4500 BC Bronze Age- 3200 BC- 1200 BC Iron Age- 1200 BC- 332 BC Hellenistic Period- 332 BC- 63 BC Roman Period- 63 BC- 476 Byzantine Period- 330-1453 Middle Ages- 476- 1350 Reniassance-1350- 1600
10) What is an eon, epoch, era, and age? An eon is the longest division of geological time. An epoch is a long period of time marked by a predominant or important person. An era is a long period of time. An age is a period of time in which something or someone has existed.
11) List three ancient calendars. Three ancient calendars are the stonehenge, the Egyptian calendar, and Aztec calendar stone.
12) List two ancient clocks and how they worked. Two ancient clocks were the sun clock and the water clock. The sun clock worked by moving shadows that formed a kind of sundial, allowing people to separate the day into morning and afternoon. The water clock worked by using stone vessels with sloping sides and letting water drip at a nearly constant rate from a small hole near the bottom.
13) What was a revolution of timekeeping? During the middle ages of Europe, the sundials became more developed. In the early 14th century, large mechanical clocks started to appear in towers.
14) What allows for standard more accurate clocks? A balance wheel and spring assembly made clocks accurate.
15) What are time zones? A time zone is a region on earth that has a legally mandated standard time referred to as local time.
16) What is the prime meridian? The prime meridian is a line of longitude which is defined to be 0'.
17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii? It would be 11:00 am in Toronto, 4:00 pm in London, 7:00 pm in Moscow, 1:00 am in Tokyo, and 6:00 am in Hawaii.
18) What is Daylight Saving Time? Do we use this in Saskatchewan? Daylight saving time is when clocks are set one hour or more ahead of standard time to provide more daylight at theend of the working day during late spring, summer, and early fall. It is not used in Saskatchewan.
19) Is there a year zero? No there is not a year zero.
20) Are we starting a new decade in 2010 or 2011? We are starting a new decade in 2011.
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.
22) What is cyclical time? Time that repeats itself in circular motion.
