The most popular and accepted theory for the origin of the universe is the Big Bang Theory. This theory states that the universe began about 10 billion years ago in a violent explosion; every particle started rushing apart from every other particle in an early super-dense phase. This explosion sent energy and matter flying all over the place. However‚ there is an argument about whether time and space existed before the big bang‚ or did the big bang create time and space. As the universe expanded

that time period. The original source of fire undoubtedly was lightning‚ and such fortuitously ignited blazes remained the only source of fire for aeons. In reality humans most likely made the discovery of fire making from spontaneous eruptions of earth gas‚ lightning strikes and vulcanic eruptions which were common in east Mid-Africa where Homo Sapiens and many other hominids lived in prehistoric times. In an ancient site in Israel called Gesher Benot Ya’aqov burned wood and seeds were discovered

Earth with No Moon A world with no moon would be much different without the Moon. Without the moon‚ Earth would be greatly different. The length of the day would be different‚ the origins of life on Earth would be slowed‚ and the biological evolution of life on Earth would vary greatly. But there would still be life on Earth‚ and many things on Earth would remain the same. Lunar tides are perhaps the most obvious effect of the Moon on Earth. The Earth without the moon would have a day that

ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

How was the Earth formed and why do we live in it is a question many of us would like to find out‚ but there are many answers to these questions and we cannot come up with a conclusion. The theory that is said to explain the formation of our earth is called the Big Bang Theory. This theory explains that

Implication of EMH EMH and Technical Analysis Technical analysis bases decisions on past results. EMH‚ however‚ believes past results cannot be used to outperform the market. As a result‚ EMH negates the use of technical analysis as a means to generate investment returns. With respect to fundamental analysis‚ the EMH also states that all publicly available information is reflected in security prices and as such‚ abnormal returns cannot be achievable through the use of this information.
