The First Three Minutes: A Modern View Of The Universe

Just under seven years ago, astronomers using the Hubble space telescope presented results they hoped would help answer one of the most contentious issues in astronomy of the 20th century – the question of the distance scale of the universe. But there was some unease when the result was announced. According to the report, other galaxies were close enough that, extrapolating backwards from their current rate of recession and making adjustments for the influence of gravity, they all would have been together (that is, the Big Bang would have occurred) as recently as 8 billion years ago. Unfortunately, there was strong evidence already in place that some stars were at least 12-15

The currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state.

Since then, the origin of the universe became a very big question to everyone. The curiosity we possess help us seek answers from different questions we can think of. Different hypotheses and ideas were formed with great scientific evidence to prove that the universe began as a single primordial atom. The scientists even found out that the universe is expanding because of the great amount of dark matter present in it. However, with these ideas, the religious thinking of people could not be removed. The concept of God being the Creator of all the things that existed contradicts the views of the theories formed. The stories and verses contained in the bible are different from the results of studies connected to it. Here, I investigate the things

Our place in the universe, by Alan Lightman, states, about how we think that the universe was and how evolves with the evolving science. Everything started when he went to vacations with his wife, to the Geek islands. They rent a boat, and they went too far away. At some point, they couldn’t see other boats and other land. So he saw how big the ocean was, how alone he was with only water around him. He started to compare the ocean with the universe. He felt intimidated, sacred that the universe could be like an ocean, with no limitations and lost in the big darkness, where you’re kind of alone in the big universe. I want to analyze the point that he states, “I felt insignificant, misplaced, a tiny odd trinket in a cavern of ocean and

There have been many theories concerning what the universe looks like, how it became this way, and where it is going. The most popular theory that people hold today is that the universe began when all the matter ever present in the universe was contained in a tiny speck and that spec exploded. This is known as the Big Bang. This theory has developed a great deal since it was first conceptualized and continues to evolve today. Many different scientists have had a hand in this.

Developed over many years and by many people, the theory states that about 15 billion years ago the universe was compressed into an infinitely small space, known as the primordial atom. It exploded in a sudden burst of energy and created a small,

For my book report I the novel Welcome To the Universe, written by Neil deGrasse Tyson, Michael Strauss and J. Richard Gott. This novel explains the physics of the universe and talks about many scientist who made these discoveries by moving from the earth outward. The book opens talking about the size and scale of the universe and how small and insignificant Earth seems within the universes extreme size. Next introduces the earliest scientific discoveries, such as the discovery of gravity by Isaac Newton. The book continues by explaining the stars and the different characteristics that each of them have, like how to find a stars brightness using lumosity. Eventually the view expands to the explanation of galaxies. It talks about the interstellar

The rate of expansion of the universe, first derived as a possibility by Alexander Friedmann through his work with general relativity and his own Friedmann equations [1], was first observationally confirmed and roughly estimated by Edwin Hubble in 1929 [2], and has since appropriately come to be known as the Hubble Constant. Hubble’s work & observational data confirmed that the recessional velocity of a given galaxy was linearly related to the distance between the observed galaxy and the observer, and this relationship could be expressed (as Hubble’s Law):

Throughout the very first moments to have existed in the universe, was the big bang. Before this the universe was extremely hot and dense. As the universe began to cool, circumstances changed just as the building blocks of matter being the quarks and electrons of which we are all made, began to arise. Within a few millionths of a second later,

After reading and trying to understand the first chapter of Death from a Distance and the Birth of a Humane Universe: Human Evolution, Behavior, History, and Your Future, I started doing a little research on the subject. One of the points that I found more interesting is our uniqueness as human beings.

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 book review is based upon the book The Cosmic Race, written by Jose Vasconcelos and then translated and annotated by Didier T. Jaen, afterword by Joseba Gabilondo. This book is published by Johns Hopkins University Press and copyright in 1925 by Herederos de Jose Vasconcelos.

Secondly, The Hubble's law states that, galaxies are moving away from us at speeds which are directly proportional to their distance. The further away a galaxy is, the faster it is moving away. Edwin Hubble (1889-1953) who is responsible for the creation of the law, discovered the phenomenon in the year of 1923. Edwin Hubble is also known as the father of the expanding universe. This observation made by Edwin Hubble shows us that or suggests that at one point of time, the universe was in fact compressed/compacted. (Bradshaw, John 2009).

The scientific community had no inkling that the universe was made up of more than what we can see until the 1930’s. A Swiss astronomer—Fritz Zwicky—was measuring the speed of the orbits of galaxies in the Coma Cluster (Ferris). His calculations indicated that the

So now that we have the basics of the Big Bang Theory, what happened after the initial expansion? In the fractions of the first second after creation what was once a vacuum began to expand into the universe. Immediately after the Big Bang the universe was tremendously hot as a result of both matter and antimatter moving apart in all directions. (For every type of matter particle, there also exists a corresponding antimatter particle. Antimatter particles look and behave just like their corresponding matter particles, except they have opposite charges.) As it began to cool there was about an equal abundance of matter and antimatter. As these two materials are
