Over the years, the origin of the universe has been questioned and debated. Experimental and evidence has allowed scientists to refine theories and present the most commonly accepted theory of ‘The Big Bang’. The Big Bang Theory is the most common explanation of how the universe started. According to the theory, our universe started as a ‘singularity’ – singularities are zones in the universe that defy our current understanding of physics, they are believed to exist at the core of black holes. Our universe is thought to have started as a singularity and expanded and cooled over the next 18.8 billion years, going from being very small and very hot into the place we know today. A priest named Georges Lemaitre first suggested this theory in the …show more content…
Redshifts are used to track the rotation of the galaxy and measure the expansion rate of the universe. The redshift is better explained with the help of the Doppler Effect or otherwise known as the Doppler Shift. This effect states that the wavelength and frequency of a wave changes for an observer who is moving to the wave source. An example of the Doppler Shift can be when the pitch of a siren varies when it approaches, passes and moves away from the observer.
Many people had noticed the red shift but it was Edwin Hubble who really explained it in 1929. He matched the redshifts with distance estimates to the galaxies and discovered that the further away a galaxy, the faster it’s receding. Therefore, his theory related directly to the Big Bang Theory of how the universe was and still is

The discovery was watched by Arno Penzias and Robert Wilson in 1965 at the Bell Telephone Laboratories in New Jersey. Whilst researching faint microwave signals from the Milky Way, they found a noise coming from an unknown origin. St first they thought that it was just birds on the antenna equipment, but that wasn’t the case, even after the birds were all gone the noise continued. Unexpectedly, researches at Princeton University were devising an experiment to find the CMB and when they heard about what had happened at the Bell labs they realised instantly that the CMB had been
On the night of October 1, 1847 Maria Mitchell discovered a comet just above the North Star. But by the time her letter of discovery reached William Bond (director of the Harvard Observatory) Father de Vico at the Vatican Observatory in Rome had already announced his discovery of the same comet on October 3. Professor Bond began a campaign to get Maria her rightful award.
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.
Throughout history there has always been discussions and theories as to how the universe came to be. Where did it come from? How did it happen? Was it through God that the universe was made? These philosophies have been discussed and rejected and new theories have been created. I will discuss three theories from our studies, Kalam’s Cosmological Argument, Aquinas’s Design Argument, and Paley’s Design Argument. In this article, I will discuss the arguments and what these arguments state as their belief. A common belief from these three theories is that the universe is not infinite, meaning that the universe was created and has a beginning date. Each believe that there was a God, deity, or master creator that created the universe for a reason. They also believe that
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.

The number of theories surrounding how the universe materialized is nearly endless, but Krauss’ thesis is one of the most convincing and buttressed that has been proposed. Lawrence Krauss is one of the most well respected theoretical physicists and cosmologists in America and has done extensive research on how and why the universe is in existence. Like the title of his book, A Universe from Nothing: Why There is Something Rather than Nothing, his entire theory surrounds the fact the universe was created from nothing. In support of his argument, he explores the weight and shape of the universe, dark matter and energy, quantum mechanics, visual particles, and expansion rates. While the world may never know exactly how the universe was created, society is getting closer to figuring it out and Krauss may have been the one to figure it out.
After discovering the approximate age of the universe to be roughly 14 billion years old I was fascinated. To even try to fathom the idea that everything within the Universe has probably existed for such a vast amount of time is almost incomprehensible. It makes one wonder what our own significance is in this world which makes up a small amount of the Universe. Why were we even put here? Honestly, the Earth would probably be a lot happier if we were never put here because all we have done to this planet is destroy nature and use all of the natural resources available to us. So why are we apart of this vast scale of the Universe? Will mankind eventually discover more of the Universe and find other planets that are inhabitable? Similar questions were asked and answered in an essay written by Alan Lightman.
George Smoot’s discovery of the blackbody form and anisotropy of CMB, has been accredited one of the most important scientific discoveries ever. His research supports the widely accepted theory of the beginnings of our universe and opens up new doors for research and understanding the patterns of our seemingly random universe.
The Big Bang is a theory that the universe was created in a very large
To more fully understand the Big Bang theory and the evidence on which it progressed from, an overview of its earlier development over many centuries is needed. Present day ideas concerning the Big Bang theory can be seen as having first originated within modern European science. However before these ideas were developed, most explanations concerning the origins of the universe were based on religious themes and concepts, the primary tradition being Christianity. These Christian origin stories explain the appearance of the universe as being the work of an all powerful and omnipresent God. It is within this tradition that one of the first scientific attempts at understanding our universe’s origins came to be. By third century CE, many Christian theologians had been working towards dating the exact moment the universe began. Their research was based on the the generations recorded in the Old Testament of the Bible - the Bible being an ultimately authoritative source according to their religion. It was estimated by these theologians that the universe was over 4000 years old. Tying in with this early Christian cosmology was the work of Ptolemy of Alexandria, a Roman-Egyptian astronomer and mathematician. Ptolemy is notable for dismissing early Greek models of the universe, which were generally accepted. Ptolemy argued that it was the earth that lay at the centre of the universe, as opposed to the sun. This was argued against by Christian theologians, who maintained that the Earth was far too imperfect and full of sin. Despite this, most people accepted Ptolemy’s model, in which the sun and planets rotated around the earth. Not only did it explain the movements of the solar system, but it further fit in with the idea that if the earth ...
As is evident by the vast number of cinematic interpretations of possible events, communication with extraterrestrial life has been a fascination of humans for years. The complex that grew to be known as the Fermi Paradox only exacerbated this fascination, as it accented the unlikeliness that if there is life elsewhere in our own galaxy, we have yet to know anything about it (https://www.seti.org/seti-institute/project/details/fermi-paradox (Links to an external site.)Links to an external site.). This desire for contact has grown and culminated in the largest deliberate broadcast with the intent of establishing contact with interstellar life: the Arecibo Message (https://www.space.com/20984-arecibo-observatory.html).
The Big Bang theory states that although the universe is currently cooling and expanding, the universe was once much hotter and smaller. The most compelling evidence for the proof of the Big Bang theory are the movement of distant galaxies, the expansion of space time, and the hydrogen and photons in the universe.
Around 15 billion years ago, a huge explosion occurred and it started the expansion of the universe. This explosion is known as the big bang. What existed before this event is completely unknown can only be speculated upon. The Big Bang basically involved an explosion of space within itself unlike a normal explosion of a bomb were fragments are thrown outward. The Big Bang then began laying the foundations for the universe. The first stars form 100-200 million years after the Big Bang, and reionized the Universe. After that, the first supernova exploded and spread nitrogen, oxygen, silicon, magnesium, carbon, and iron through uranium throughout the Universe. A supernova is a the explosion of a star, it is the largest explosion which takes place in space, radiating as much energy as the sun is supposed to in its entire life span. The solar system then formed 4.6 billion years ago.
The first observation was that it was expanding, which means that it would separate galaxies and they would become larger. The galaxies used to be extremely close together before some kind of explosion, which is the big bang theory. Second, the big bang theory explains the “Abundance of helium and other nuclei like deuterium in the universe. Third, astronomers could not actually see the background radiation. The last evidence concluded the theory of the universe, beginning with Stephen Hawking saying “It is discovery of the century if not of all time.
Since the dawn of intelligent man, humanity has speculated about the origins of the universe.
