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

The first piece of evidence that they had for the big bang was that they soon realize that the universe kept expanding. The second piece of evidence that they had about the big bang was The cosmic microwave background radiation. These two pieces of evidence support the big bang theory because they led to the conclusion that the big bang did occur. This big bang evidence helps us understand that the big bang made the universe expand every day. The most important

than the expected from this event the scientists concluded that the universe’s expansion was accelerating. The claim that dark energy exists is support by the Integrated Sachs Wolfe effect. This effect states that “light forms the cosmic microwave background-- radiation present throughout the universe that was created by the Big Bang-- would come more blue in color as it passed through the gravitational fields of lumps of matter.” But many other scientists do not accept that dark energy exists because

amounts of protons and neutrons at this stage; approximately 1 for every one billion photons‚ neutrinos or electrons (Maffei). The density of the Universe in its first moment of life is thought to have been 1094g/cm3 with the majority of this being radiation. For each billion pairs of these heavy particles (hardens) that were created‚ one was spared annihilation due to particle-antiparticle collisions. The remaining particles constitute the majority of our universe today (Novikov). During this creation

The Big Bang theory states that all the matter that is in the universe was once in a very small amount of space with infinite temperature‚ pressure‚ and density. This theory is well supported and there are many reason for it’s support. One main reason is that no one really has a clue and The Big Bang Theory seems far fetched but more reasonable than any other ideas that there are out there. Some of the important thing to know about the big bang to understand are the beginning and the few seconds

of time‚ all of the matter and energy in the universe was concentrated in a very dense state‚ from which it "exploded" and this is known as the Big Bang. The Big Bang marks the instant at which the universe began. From a dense‚ hot ball of gas‚ radiation and subatomic particles. This exploded and began expanding rapidly outward. As it expanded it cooled and electrons‚ protons and neutrons formed. As the universe grew in size‚ the temperature dropped‚ which eventually formed huge numbers of Hydrogen

the radiation was too weak to detect. He predicted that although the radiation would have begun as visible light at the Big Bang‚ it would have shifted down to microwave radiation by the time it reached Earth. He would prove this prediction correct. (Feuerbacher). Sixteen years later in 1964‚ Arno Penzias and Robert Wilson‚ radio astronomers who were attempting to get rid of what they thought was background noise on their radio signals when they realized it was something else. The radiation they

The Creation of the Universe In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves‚ which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence
