Essay on The Big Bang Theory

Cosmic background radiation is radiation from the early development of the universe. After the big bang the universe was smaller and much hotter than it is now and was filled with a fog of hydrogen plasma. Eventually the universe started expanding and became cooler. As it cooled stable atoms started forming, leaving only CMB remained so it is a strong evidence that the Big Bang Theory was correct. Scientist thought if the big bang actually happened then there would have to be cosmic background radiation left over, so all they had to do is find evidence of this and they did so this gave the big bang theory evidence to support their claim.

In the first place, Edwin Hubble was an astronomer who found important information of the BBT. His findings originated the Big Bang Theory in the first place. (“The Big Bang Theory”, n.d.) In 1929, Edwin Hubble declared that the universe was increasing and that most galaxies were moving away from us. (Redshift and Hubble’s law, n.d.)  This shut down Einstein's theory that the universe was static (“Hubble’s Law”, 2015)Also, “his theory states that the Universe must have been created in this single event which came to be known as the "Big Bang" through expanding at an

This paper looks at the Big Bang Theory. It examines the history of the theory and the scientific ideas on which it is based. It also examines some of the evidence proving the Big Bang and addresses some of the more common arguments against it.

What were the key ideas and observations that led to the development of the Big Bang Theory? First, scientists found that the universe is expanding. The observation that led them to conclude that everything used to be extremely close together before some kind of explosion occurred. Second, the big bang perfectly explains the abundance of helium, hydrogen and other elements in the universe. According to the Big Bang Theory, a very hot soup of elementary particles flew apart at an astonishing rate and filled the universe. These particles in abundance are what we observe today. Third, Penzias and Wilson detected radiation in their efforts to survey the Milk Way by using a radio telescope. Their intention was to measure radio sources of the

The law that Edwin Hubble created has ultimately supported the Big Bang Theory and our knowledge of galaxies. It states that Recessional Velocity is equivalent to Hubble's constant times distance, or V = Ho D. This basically says that the farther a galaxy is

Edwin Hubble was an American Astronomer and Scientist that lived from 1889-1953. As a kid he began reading science fiction novels and fell in love. In 1906, Hubble attended the University of Chicago where he studied law philosophy. He graduated three years later with a bachelor's degree in jurisprudence. Not long after he decided to attend the University of Chicago once again and study Astronomy. He graduated from the University of Chicago and immediately served in WWI before pursuing the field of astrophysics. Then, California’s Mount Wilson Observatory recruited him to help complete the construction of their Hooker Telescope. While working at the

The Hubble Space Telescope is a telescope that was launched into space in 1990, April 24th. Its primary function was to take pictures of stars, planets, moons, galaxies, etc. This type of telescope is different from a telescope such as the Hooker Telescope as it is in space, rather than on Earth, and was used for different things. Over the many years that this extraordinary telescope has orbited in space, it has helped scientists with many new discoveries and refined previous theories or beliefs. One of the biggest discoveries this telescope has made is the discovery of galaxies that we did not know of previously because they were so far away. This discovery was very important as it has lead scientists to calculating a more accurate age of the universe. The Hubble Space Telescope made this discovery by observing Cepheid variables, which are stars with the same average brightness. Although, their brightness is essentially the same, the stars would seem either brighter or dimmer depending on its position in relation to Earth. For example, if one Cepheid variable was 100,000 light years away and another Cepheid variable was 200,000 light years away, the second star would seem dimmer as it is further away from the Earth and our perspective makes it look like it is not as bright. Scientists can use this observation to work out around how far away a Cepheid variable, and ultimately a galaxy, is from the Earth. Using this information and the pictures taken by the Hubble Space Telescope, scientists were able to work out a more accurate age of the universe which was around 13.75 billion years old. Without this sort of technology, we wouldn’t know as much about the universe as we do now and we may not have been able to refine our knowledge on the age of the universe. To sum up, the Hubble Space Telescope is an important piece of

The Hubble Space Telescope has been key in not only confirming the universe’s expansion but also the further defining the rate of the expansion. Edwin Hubble in 1929 provided the first evidence of the expansion of the universe and its finite age with his Hubble constant. The constant says that the farther a galaxy is the faster the acceleration, therefore the universe is expanding. The ability of the Hubble Telescope to resolve Cepheid variable stars farther out than could previously be done by ground based telescope allowed scientists to see further out and therefore longer periods of time than they ever could before. This ability to look further back in the past has allowed scientists to better define the expansion rate of the universe. When Hubble was first launched, the expansion rate was estimated between 50-100 km/sec/Mpc. In 1994 it was determined to be 80 km/sec/Mpc with a 10 percent rate of error. In 2009, scientists, using observations of Cepheids in faraway galaxies, were able to narrow

The three separate and specific pieces of scientific evidence that support the Big Bang theory are the great quantity of elements that was discovered, such as hydrogen, helium and other elements which exactly what scientist would expect to find if the Universe was once a huge star. Secondly, the discoveries of galaxies and how they are moving away from earth. Scientific theories predicted that after the Big Bang, there were large amounts of radiation released, and that this radiation moved away from earth and that the wavelength of this radiation shifted from visible light to cosmic microwave background radiation. Finally, the discovery of how the galaxies were formatted in the universe, another scientific theory states that after the Big Bang

Which means that they at one point must have been touching each other. To help verify this was Edward Hubble who found there is a directly proportional “relation between Redshift and Distance”(pg.22). Meaning galaxy’s light spectrum increases in wavelength from the light we receive from a galaxy and the speed with which it moves away from earth. He used that to calculate the distance of the galaxy from Earth, and then approximated the age for the universe. “There is... a way to confirm that the galaxies are really moving apart, as indicated by the red shifts”(page32). This discovery was a great importance to the Standard Model. Once it was clear that the universe was expanding, Hubble proceeded to calculate the speed the galaxies that are moving away from us. A constant now called “Hubble’s constant”, which determines that galaxies increase in constant proportion to their distance. The next thing important to the Standard Model was the Theory of General Relativity published by Albert Einstein. His model predicted an expanding universe; “in order to achieve a model that fit…Einstein was forced to mutilate his equation by introducing a term called cosmological constant”(page 35). Which made the formula consistent with a static Universe. The next important thing about the Standard Model was when the radiation expanded, dropped frequency and gained wavelength. There was “diffuse background of radio static left over from near the beginning of the universe”(page46). “Arno A. Penzias and Robert W. Wilson, set out to use the antenna to measure the intensity of the radio waves emitted from our galaxy at high galactic latitudes, out of the planes of the Milky Way”(page46). Which confirmed the Standard Model theory that remained

The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000

This article talks about one of the most famous concepts of science, The Big Bang Theory. The article talks about how it is theorized that before the “Bang,” the universe was filled with nothing more than loose particles and radiation. After about a trillionth, of a trillionth of a second, the universe rapidly expanded and all the energy that would ever be created, was created. According to the article, The Big Bang happened when one single primordial atom imploded on itself, and expanded. However, no one knows exactly what spawned this universe; making it one of the most controversial topics in the scientific world.

Religion Assignment Q1. Creation: Scientific explanation. There are many scientific creation theories around the world , but the most prevalent ones all are based around the Big Bang theory. The Big Bang theory is a belief that the world began with a small singularity and began expanding over the next 13.8 billion years, to the cosmos that we are all familiar with today. Majority of the information about the Big Bang theory comes from mathematical formulas and models.

Have you ever wondered about the start of time? How about the start of the universe? Well, this question has been nagging astronomers and scientists alike for years and years. But in 1927, Georges Lemaitre proposed one of the most controversial theory of all time, the Big Bang.

This observation means that it has taken every galaxy the same amount of time to move from a starting position to its current position. This observation is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this in 1929. Edwin Hubble’s evidence supports the expansion of the universe and suggests that the universe was once compacted. Third, if the universe was insanely hot as the Big Bang suggests, scientists should be able to find some of this heat left over. In 1965, Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin Cosmic Microwave Background radiation which infuses the observable universe. This is thought to be the remnant that scientists were looking for. Finally, the discovery of great amounts of Helium and Hydrogen lead to support the Big Bang Theory. (LaRocco)
