Background radiation Essays

beginning of the Universe. This theory shows how the Universe was created and that there was a beginning. This theory was developed by Steven Hawking. Throughout this essay, I will be discussing evidence of the Big Bang such as Cosmic Microwave Background Radiation, mixtures of elements and the expansion of the Universe. There will also be some irrelevant yet relevant topics such as supernovas, dark

The big bang theory that we know today has been refined over a 100 years as advancements in technology have improved and ideas have been proven or disproven with the aid of the scientific community and scientific evidence. The Big Bang theory is widely accepted amongst scientists today. The theory breaks down the origins of the universe and how the universe came into existence. The main premise of the Big Bang theory is that the universe was formed through a period of rapid inflation and expansion

The model accounts for the fact that the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background, large scale structure and the findings by the astronomer Edwin Hubble (1889-1953 -Hubble’s laws). If the known laws of physics are extrapolated beyond where they are valid, there is a singularity. Modern measurements place this moment at approximately

flowing in. George Gamow, Ralph Alpher, and Robert Herman worked on a detailed picture of the Big Bang, soon realizing that immediately after the explosion the universe would have been incredibly dense and extremely hot. This period is called the radiation era because at those temperatures the majority of the universe existed in the form of

accepted because of its proficiency in simply explaining the three major cosmological observations. Those three observations are: the expansion of the universe as measured by the redshift of light released from galaxies, the presence of the cosmic background radiation and, the comparative amounts of hydrogen, helium, and deuterium in the universe. The vast majority of astronomers believe that the Universe started with the Big Bang around 14 billion years ago. Before the Big Bang, it is theorised that the

The Big Bang Theory is the main accepted explanation on how the universe was created. It paints a picture of the way and time that the universe began. The theory states that there was an unimaginably violent explosion which created matter, radiation, space and time which became a fireball. As the fireball cooled down, it expanded and became thick gases which then became dense clumps. It continued to cool down and the gases formed galaxies and stars were formed. Some stars then created planets which

that scientists and astronomers believed that there had to be left over heat and radiation somewhere within the universe to prove it. While studies on the Big Bang Theory began in the 1910s, the study of heat and radiation were not tangible yet. It wasn’t until 1965 when Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin CMB, or Cosmic Microwave Background radiation. “Cosmic Microwave Radiation is radiation that fills the universe and can be detected in every direction. Created shortly

a law describes a single action. Where on the other hand a theory explains an entire group of related phenomena. The group did not mention it, but in every direction, there is a very low energy and very uniform radiation that we see filling the Universe. It is cosmic background radiation, which is the afterglow of the

The Big Bang – Information sheet 13.7 billion years ago, the universe was created by matter expanding at a rapid pace causing extremely high temperatures and density to form otherwise known as, the Big Bang. According to the theories of physics, if we were to look at the Universe one second after the Big Bang, all we would see is a 10-billion-degree sea of neutrons, protons, and electrons. As time went on, we would see the Universe cool, causing the neutrons to either decay into protons or electrons

theory is accepted by most astronomers as the best explanation of the origin of the universe The Big Bang theory offers an extensive explanation for a broad range of observed phenomena like the abundance of light elements, the cosmic microwave background, large scale structure, and Hubble's Law. The Big Bang theory does not provide any

If it was found out that other galaxies are not moving further, and further away from us quickly. This would cause the Big Bang Theory too lose its credibility. Also if many other pieces of evidence were found out to be untrue , I believe this theory would lose much of its credibility. The first part of this theory, I will be discussing my main point, which is whether galaxies are moving away from us or not and at what speed. According to Hubble's law, the universe has been expanding since the

This theory was supported by other astronomers who observed cosmic microwave background and galaxy redshifts. In the early 21st century, telescope technology became more advanced and more satellites were created e.g. the Hubble Space Telescope. Due to the advanced technology astronomers are able to precisely calculate and measure parameters

images and theories developed. Technology 1 - The COBE satellite The COBE satellite (displayed in source 1) is known to have confirmed the Big Bang theory. As astronomers continued to examine the radio signals of the Milky Way, they kept receiving a background signal which interfered in all directions with their

This radiation, located throughout the Universe, is a body with a temperature below 3 degrees Kelvin, which is approximately -270 degrees celsius. The CMB is some of the leading proof scientists have to back the Big Bang theory, as only this type of phenomena could have been created in an event, an explosion, on such a scale as the Big Bang. The Cosmic Background Radiation was discovered by two men named Arno Penzias and Robert Wilson. This

bang wasn’t always the accepted theory in the scientific community to describe how our universe formed. The current major pieces of evidence that support the big bang theory are. Redshift:The universe is expanding. CMBR:cosmic microwave background radiation, energy released shortly after the big bang Observing distant stars:Inspecting the elemental composition in these ancient stars. Redshift occurs when galaxies move further away from us, and is observable by a red-shift of light from distant

The Big Bang describes a sequence of events responsible for creating the early universe, which over billions of years progressed into the universe as we know it today. Through observable modern science, we are able to offer strong proof for its occurrence. This includes the movement of galaxies, the expansion of space-time, and the presence of hydrogen atoms and photons in the universe. While each of these pieces of evidence do not provide fully convincing arguments when viewed individually, they

One may wonder how has the Big Bang Theory came about? Who created this controversial topic that has created multiple shows, newspaper articles and more? The Big Bang Theory or the “beginning of time” theory is still to this day an ongoing hot topic that has people questioning how, what and when? Well it all started with the creator of this concept by a Belgian cosmologist and Catholic Priest born in the 1800’s, by the name of George Lemaitre. Writing a paper in 1931 he came up with his own abstraction

The Big Bang symbolizes the instant the universe began, when time and space came into existence and all matter in the cosmos launched into expansion. Prior to this all four fundamental forces (gravity, electromagnetism and the strong and weak nuclear forces) were combined. The explosion was one of space within itself. It was not like the explosion of a bomb where fragments are thrown outward (LaRocco 1). The galaxies were not clumped together. During the first second or so of the universe large amounts

asking for centuries in a cohesive way. In this report I will investigate and explain the four main parts of the big bang theory, often referred to as the ‘Four Pillars’. These ‘Four Pillars’ are: - The Expansion of the Universe theory - Cosmic background radiation - The formation of galaxies and large-scale structures - The relative amounts of hydrogen, helium and deuterium in the universe Ever since its inception and realisation by Georges Lemaitre in 1927, the big bang theory has been added to and
