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

However‚ not all planets have moons. Based upon what we learned in the astronomy course of how everything has a beginning and an ending. Our solar system got created from the cloud that was the Solar Nebula. All stars exist in island called galaxies‚ and galaxies contain old and new stars as well of clumps of dust clouds. These clouds mostly contain hydrogen and some heavier metals. However‚ any elements that is heavier than helium is considered to a metal by Astronomers. The formation of the solar

Hubble’s law states the further away stars and galaxies were‚ the faster they were going.Thefact that most galaxies are moving away suggests that the universe is expanding. 6.Explain the big bang theory. 14 billion years ago‚ the universe exploded from a singularity containing a lot of concentratedenergy.

standard model seems consistent with what we can observe and experiment but it still doesn’t cover every phenomena. Indeed‚ the theories concerning gravitation (Newton’s laws and General relativity) return great results when explaining rotation of galaxies‚ gravitational pull‚ etc. however these theories rely upon classical quantum field theory physics and completely break down as we approach the subatomic scale. The standard model mainly relies on the quantum branch of physics which deals with subatomic

Hence this theory proved that all the distant stars ‚ galaxies are moving away from the Earth i.e the universe is expanding. The apparent radial recession velocity away from Earth can be calculated following the Doppler equation: n/no= (1-v/c) (3) n: a specific frequency of the arriving light‚ no: corresponding
