Are the Big Bang Theory and Nebular Hypothesis correct?
Over the years, science has reached new levels of advancement and many scientific laws have been established in order to explain the way our universe functions. Using these laws, many scientists have come up with promising explanations for the formation of the universe and our Solar System. The Big Bang Theory, for example, explains that at one point in time, the entire universe was inside a tiny bubble hotter and denser than anything we could imagine. Suddenly, the bubble exploded and the universe was born. Over time, it began to grow from smaller than a single atom to an entire galaxy, and it is still expanding today. First suggested by physicist and priest Georges Lemaître, it is the

In fact, to call this concept merely a theory is to underestimate the overwhelming amount of evidence. There is also a hypothesis designed to explain the formation of our Solar System. This idea, proposed by Pierre Simon de Laplace in 1976, is known as the Nebular Hypothesis and states that the material from which the solar system was formed was once a slowly rotating cloud, known as a nebula, of extremely hot gas. The gas cooled and the nebula began to shrink. As the nebula became smaller, it rotated more rapidly, becoming slightly flattened at the poles. A combination of centrifugal force and gravitational force caused rings of gas to be left behind as the nebula shrank. These rings condensed into planets and their satellites, while the remaining part of the nebula formed the sun. While much progress has been made in determining the exact formation of the Universe and Solar System, these two widely accepted …show more content…
According to the Big Bang theory, many of the elements that we see today were created as the universe expanded and cooled down. In the earliest moments after the explosion, there was nothing more than hydrogen compressed into a minute volume of high heat and pressure. The theory suggests that the universe was acting like the core of a star, combining hydrogen into helium and many other elements. This concept has become known as Big Bang Nucleosynthesis, and has been supported by the fact that many astronomers have looked out into the universe, measured the ratios of hydrogen, helium and other trace elements, only to find that they match the ratios they would expect to find if the entire Universe was truthfully once a big
...f gas, which collapsed and broke up into individual stars. The stars are packed together most tightly in the center, or nucleus. Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies
There then amassed immeasurably vast and elegant clouds composed principally of the simplest and most adulterously insouciant stable element then, as now – some fourteen billion years later: Hydrogen. These forming and expanding seas of the single proton element circulated within, amongst, and against themselves even as they swirled and eddied in the expanding Creation, carrying in their undertow their less numerous but heavier siblings in the mix.
In support of his thesis that the universe spawned from nothing, Krauss points towards the big bang theory. The original theory was that everything was static, but Edwin Hubble proved this invalid, that the universe was actually expanding. Using advances in telescopic technology and previous knowledge of the light from stars, he correctly made this assertion. Using the very same scrutiny, Hubble determined that our Milky Way galaxy was not the only one in the universe. Krauss uses this theory to demonstrate that an expanding universe mean...
Solar nebula is a rotating flattened disk of gas and dust in which the outer part of the disk became planets while the center bulge part became the sun. Its inner part is hot, which is heated by a young sun and due to the impact of the gas falling on the disk during its collapse. However, the outer part is cold and far below the freezing point of water. In the solar nebula, the process of condensation occurs after enough cooling of solar nebula and results in the formation into a disk. Condensation is a process of cooling the gas and its molecules stick together to form liquid or solid particles. Therefore, condensation is the change from gas to liquid. In this process, the gas must cool below a critical temperature. Accretion is the process in which the tiny condensed particles from the nebula begin to stick together to form bigger pieces. Solar nebular theory explains the formation of the solar system. In the solar nebula, tiny grains stuck together and created bigger grains that grew into clumps, possibly held together by electrical forces similar to those that make lint stick to your clothes. Subsequent collisions, if not too violent, allowed these smaller particles to grow into objects ranging in size from millimeters to kilometers. These larger objects are called planetesimals. As planetesimals moved within the disk and collide with one another, planets formed. Because astronomers have no direct way to observe how the Solar System formed, they rely heavily on computer simulations to study that remote time. Computer simulations try to solve Newton’s laws of motion for the complex mix of dust and gas that we believe made up the solar nebula. Merging of the planetesimals increased their mass and thus their gravitational attraction. That, in turn, helped them grow even more massive by drawing planetesimals into clumps or rings around the sun. The process of planets building undergoes consumption of most of the planetesimals. Some survived planetesimals form small moons, asteroids, and comets. The leftover Rocky planetesimals that remained between Jupiter and Mars were stirred by Jupiter’s gravitational force. Therefore, these Rocky planetesimals are unable to assemble into a planet. These planetesimals are known as asteroids. Formation of solar system is explained by solar nebular theory. A rotating flat disk with center bulge is the solar nebula. The outer part of the disk becomes planets and the center bulge becomes the sun.
The Big Bang Theory is one of the most important, and most discussed topics in cosmology today. As such, it encompasses several smaller components that attempt to explain what happened in the moments after creation, and how the universe we know today came from such a fiery, chaotic universe in the wake of the Big Bang. One major component of the Big Bang theory is nucleosynthesis. We know that several stellar phenomena (including stellar fusion and various types of super novae) are responsible for the formation of all heavy elements up through Plutonium, however, after the advent of the Big Bang theory, we needed a way to explain what types of matter were created to form the earliest stars.!
Here are some of the theories that affirm the validity of the big bang. As was written in the previous paragraph, the big bang theory grew out of Einstein’s equations of general relativity in which he related the form in which space is shaped to how matter is spread. And in the big bang theory, the universe (matter, space time, energy) is spread out as a result of an explosion. Do you now see the
Big bang theorist base their theory on the following evidence. One of the evidence that supports this theory is that galaxies appear to be moving away from us at speeds that are proportional to their distance. This is known as Hubble’s Law it’s named after Edwin Hubble who is credited for the discovery of this phenomenon in 1929. Hubble observed that the universe is expanding in every direction, which makes us come to the conclusion that the universe was once compact and is now moving away from the point of origin.
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 years later that it cooled enough so that hydrogen and helium could form by fusion processes. Even then, it took another two billion years of cooling for enough clumps of interstellar dust and gas, called molecular clouds, to achieve stability in the universe.
Our solar system, as we see it today, originally formed from the collapse of a very cold and low-density cloud of gas. The mass of this cloud was composed of 98% hydrogen and helium, 1.4% hydrogen compounds, .4% rock, and .2% metal. The nebula was thought to be a few light years across and was roughly spherical in shape. The cloud was in a state of balance, it was neither contracting or expanding, until a cataclysmic event, most likely a supernova, created a shock wave through the nebula, resulting in an area of higher mass. Once this area became more massive than the rest of the nebula it begin to collapse with the area of hig...
Firstly, universe is expanding every second since the birth of the universe. It was first a tiny spec of high concentrated mass and energy, something triggered it to explode. This explosion was called the Big Bang. This is the start of time, space and matter. This happened 13 billion years ago. The universe is made out of 21% dark matter, 4% normal matter and 74% dark energy and has more than 500 trillion galaxies. Each galaxy typically has more than〖 10 billion〗^2 stars. Each star has more than 1 planet or none sometimes. In 1961, Frank Dr...
The Big Bang Theory would be completely pointless without reasonable explanations to support it. The first evidence scientists have to support the Big Bang is the Universe had a beginning. Now the goal was for scientists to figure out what was the cause for this supernatural event to occur. Second, galaxies appear to be moving away from Earth at speeds proportional to their distance. Galaxies that are tw...
About 13.8 billion years have passed and only in the past 100 years have humans even come close to figuring out how it started. Georges Lemaitre was the first to propose the idea of the ‘big bang theory’ as the creation of the universe. the big bang theory states that all matter in the universe was originally condensed into an area smaller than the ball of a ballpoint pen and the radius rapidly expanded at a rate of one million million million million million times in less than a millionth of a second. That idea is generally accepted by most scientists, but not all scientists agree. Some scientists have created various other creation theories. Such as the steady state theory which was unveiled in 1948 by two men by the names of Hermann Bondi and Thomas Gold. Bondi and Gold had worked with Fred Hoyle to create this theory. The steady State theory suggested that galaxies were constantly moving away from each other and in between the galaxies, new galaxies would form out of newly created matter keeping the universe semi-uniform in appearance. But the steady state theory was short-lived due to new scientific discoveries, like microwave radiation. But the origin of the universe is still highly debated. One thing scie...
In particular, measurement of the number of normal isotope, which is when each of 2 or more forms of the same element containing equal numbers of protons but different numbers of neutrons in their nuclei, and hence separate the atomic mass but not in chemical properties; in particular, a radioactive form of an element, of hydrogen to its heavier isotope known as deuterium, a stable isotope, provides important insight into inside of nucleosynthesis. All other elements heavier than lithium are made by stars experiencing nuclear reactions and during powerful supernova explosions. With a couple of exceptions, we have a small, but better, understanding of how a star is created, as it converts elements into heavier elements. These heavy elements are spread into the Universe by stellar winds and supernova explosions. However, we need to understand just where and when the chemical evolution happens during the lifetime of a typical galaxy, and if our technology is good enough in its current state to predict the observations. Studying radiation due to the decay of the products, nucleosynthesis provides direct info about the synthesis of
The big bang theory has evidence to support it. An example of this evidence is the cosmic microwave background. The cosmic microwave background was discovered in 1964. The cosmic microwave background is radiation left over from the beginning of the universe or the big bang. This background is important because the radiation is the type of radiation that was seen at the beg...
I agree with the Solar Nebular Hypothesis. I am a person that likes to base my opinions scientifically. Evidence wise this theory makes more sense than any other does. I stand the same way on how the earth was created as I do with the development with humans. I believe in evolution because the evidence is there it is not just some everyday whacko’s theory. There is logic and facts to back it up. The Solar Nebular Hypothesis can be backed up as true by looking at the order of the planets and what elements they contain and their gravitational fields. I am not an expert but this is what I believe in. I disagree with the big bang theory because it just doesn’t make sense how when a huge massive ball can explode and create a solar system that has planets that rotate around a sun in the middle. If there were an explosion you would think that particles would be going every which way. With the Solar Nebular Hypothesis it makes sense that
