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.!
! Before the theory of Big Bang nucleosynthesis (BBN), physicist George Gamow predicted that the energy of the Big Bang was enough to create all of the elements in the universe. Two of his students later calculated that this was not possible. (Scientific American) Since a certain amount of energy is needed for nucleosynthesis, or the formation of heavier nuclei from smaller nuclei or particles, ...
Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”.
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
The Big Bang theory is a theory that states that the universe originated as a single mass, which subsequently exploded. The entire universe was once all in a hot and dense ball, but about 20 million years ago, it exploded. This explosion hurled material all over the place and all mater and space was created at that point in time. The gas that was hurled out cooled and became our stellar system. A red shift is a shift towards longer wavelengths of celestial objects. An example of this is the "Doppler shift." Doppler shift is what makes a car sound lower-pitched as it moves further away. As it turns out, a special version of this everyday life effect applies to light as well. If an astronomical object is moving away from the Earth, its light will be shifted to longer (red) wavelengths. This is significant because this theory indicates the speed of recession of galaxies and the distances between galaxies.
Matter, as we conceive it today, did not exist after the Big Bang, because the temperature was too high for that. While trying to join protons and electrons, light continually crossed apart. Only when the universe had cooled to 3,000 K, the atoms are held together and the light was beginning to happen.
The agnostic’s assertion may be expressed by the sentence, “We cannot know whether there is a God or not, and we cannot know whether the universe has been in existence since eternity or not.” He believes that nothing is or can be known. If the hypothesis “Matter had a beginning” is confirmed, the assertion that “Matter had no beginning” would be refuted and the contention “We cannot know whether it had a beginning or not” will be proved wrong. Thus, demonstration of the fact that matter had a beginning is a blow not only to atheism but also to agnosticism and skepticism. Once the hypothesis of the beginning and creation of matter has been confirmed, the atheists should abandon their disbelief and the agnostics their skepticism. If you remember the words in the sura The Prophets, verse 30, “Will they not believe even then?” this statement in the verse that described the Big Bang is a sign according to which the unbelievers will stick to their own convictions, or lack of conviction. It has become clear that an agnostic is no different than a man who worships the cow and the denial of the atheist is tantamount to the adoration of fire; these people base their philosophies on absolute lack of evidence, sheer delusion, total lack of logic and scientific reasoning.
Stars explode at the end of their lifetime, sometimes when they explode the stars leave a remnant of gasses and, dust behind. What the gasses come together to form depend on the size of the remnant. If the remnant is less than 1.4 solar masses it will become a white dwarf, a hot dead star that is not bright enough to shine. If the remnant is roughly 1.4 solar masses, it will collapse. “The protons and electrons will be squashed together, and their elementary particles will recombine to form neutrons”. What results from this reaction is called a neut...
Creation and Science We have all heard about the evolution vs. creation debate. Two sides opposing each other in fits of heated passion. One group believes that humans developed from monkeys, and the other group is a bunch of religious fanatics. Does this sound somewhat familiar?
There is now strong evidence pointing towards the existence of dark matter in the universe, derived from a variety of precision measurements; it is now believed that the universe is made up of roughly 5% baryonic matter, 25% dark matter and 70% dark energy (Ade, et al., 2013). Evidence exists to suggest that the dark matter cannot be made up of normal baryonic matter (Weiss, 2006) (Raine & Thomas, 2001) and it is in the investigation of the non-baryonic components that cosmology turns to particle physics. The study of elementary particle physics can provide clues as to what this non-baryonic matter could be made up of, with current possibilities being: neutrinos with mass, weakly interacting massive particles (WIMPs), axions and magnetic monopoles. These are all primeval and interact weakly with baryonic matter. I will now discuss each of these.
The Big Bang, the alpha of existence for the building blocks of stars, happened approximately fourteen billion years ago. The elements produced by the big bang consisted of hydrogen and helium with trace amounts of lithium. Hydrogen and helium are the essential structure which build stars. Within these early stars, heavier elements were slowly formed through a process known as nucleosynthesis. Nucleosythesis is the process of creating new atomic nuclei from pre-existing nucleons. As the stars expel their contents, be it going supernova, solar winds, or solar explosions, these heavier elements along with other “star stuff” are ejected into the interstellar medium where they will later be recycled into another star. This physical process of galactic recycling is how or solar system's mass came to contain 2% of these heavier elements.
...ions happen. Supernovas give off many elements we have today including hydrogen and heavier elements such as iron. Supernovas also play a big role in creating new stars because the aftermath of the explosion creates an elemental environment for new interstellar reactions to occur. Discovery of a supernova was difficult at first, given the fact that most occur far away from our galaxy, but new technology now allow scientist to discover many supernova within may galaxies.
The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen, helium, and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together, protoplanets, to eventually form planets. A great mass of the material eventually began to form together, protosun, and make up the sun.
“A major advantage of the concept of community of practice is… studies that illustrate the emergent nature of communities and the inseparability of language from actual social contexts.” (Ahearn 133) In social situations, we usually do not focus on the language that is spoken. It is only when we look at a transcript and analyze specific words and phrases. In doing this we can see which words and phrases are used by whom. These specific words and phrases that usually associate with a certain community is often exchanged between different communities.
Your universe, as we have suggested many times, as we've suggested already this morning, is but one universe among many. It is relatively a small universe — not to suggest that you should feel badly … {laughter} … for despite the consensus reality that bigger is better, despite the male-dominating energy and the comparative energies that say "bigger is better," your universe, though relatively small, is not at all diminished by its size.
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
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...
