the universe became what we see today is what scientist calls “The Big Bang Theory” not to get confused with the show. Scientist base the Big Bang theory on many different factors/observations. The most important is the “redshift” of very far away galaxies. Redshift is the doppler reaction that occurs in light. When an object moves away from earth‚ it looks reddish because the movement stretches the wavelength. The reddish color occurs because; red is the lowest wavelength on the visible. The more

knowing we do not know where we actually begin or came from‚ there must be someone that actually created us into being. Being the only one that living in the whole milky way galaxy. Earth is the only one called the living planet where we actually lived. Having different views we can conclude that a mighty being created the whole galaxy and us therfore the start of everything. Humans and animals were created together with the‚ trees ‚

Theory. This theory claims that about 15 million years ago‚ there was a sudden explosion in which matter was thrown in every direction at an unbelievable speed. Matter decelerated and started to form clouds of poisonous gas which subsequently formed galaxies‚ stars‚ planets like the Earth‚ and the sun. There are also many religious perspectives about the creation of the Earth. First of all‚ there is the Christian perspective which declares that the world was brought into existence by the seven days

The Origin of the Universe As Told by the 20th Century Peoples of North America and other industrialized lands INTRODUCTIon The evolution of theories about the origin of the universe has surely proceeded at a rapid pace upon entering the 20th Century. New telescopic devices permitting people to see parts of the universe never before imagined‚ in new ways never before conceived‚ have advanced man’s theoretical capabilites on explaining the origin of the universe‚ a task that has been

place in the Earth‚ the Atacama Large Millimeter Array or ALMA provides the most distinct and the most precise images of local stars and planet formation and can also distinguish the birth of neighboring stars and some of the most distant‚ ancient galaxies. ALMA was initially a 50-50 partnership between the United States National Radio Astronomy Observatory and European Southern Observatory (ESO). The array has been extended with the help of the new Japanese‚ Taiwanese‚ and Chilean partners. ALMA is

How did the universe originate and evolve to produce the galaxies‚ stars‚ and planets we see today? How did we get here? In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky‚ we must understand how stars‚ galaxies and planets are formed. There are many questions associated with the creation and evolution of the major

Life cycle of a star Every star has a life cycle just like a human or a frog except stars do it on a much larger scale. Stars start life as a massive cloud of matter and then get pulled together to create a star. But stars do not last forever most stars last for millions of years but they still end. When a stars life ends it may explode or implode to create a black hole. The reason stars even start life and end life is because of nuclear fusion. Nuclear fusion is a reaction where matter is forced

For about fifty years now‚ astronomers have been detecting particles with energies greater than eight billion electronvolts "bombarding" Earth. Up until now‚ the origin of these particles has been a mystery. The reason the answer took so long for us to get‚ is because these high charged particles only falls on about one square kilometer of Earth per year. With this little amount of impact‚ it was quite difficult for astronomers to determine its origin. This miraculously changed when the same type
