The Universe: Dark Matter And Dark Energy

Indeed, it was on account of HubbleÃÔ quest to prove his expansion theory, continuing forth with earnest skepticism at the various limitations others placed upon the universe, which eventually saved to establish his conjectures as reality. Due to his tenacity with regard to finding the truth, HubbleÃÔ

Dark matter and dark energy are two entities that have very little known about them, except that they make up about 95 percent of the universe. Even though this is a large part of the universe, it wasn’t even thought about until the 1960’s or the 1970’s. This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy.

The particles include photinos, neutrinos, gravitinos, axions, and magnetic monopoles, among many others. Of these, researchers have detected only neutrinos -- and whether neutrinos have any mass remains unknown. Experiments are under way to detect other exotic particles. If they exist, and if one has a mass in the correct range, then that particle might pervade the universe and constitute dark matter.

Einstein has brought many insights of life including the theory of the speed of light, which has led to the special theory of relativity that molded the way science, is today. “For example, various experiments, including the Michelson-Morley experiment, failed to measure the expected changes in the speed of light relative to the motion of the Earth. Due to this Einstein recognized that light has a measured speed that is independent of the speed of the observer” (“Albert Einstein.” 4). “Einstein showed in 1907 that mass is related to energy by the famous equation E=mc^2, which indicates the enormous amount of energy that is stored as mass, some of which is released in radioactivity and nuclear radiations, for example in the sun” (4).This enabled Einstein to be able to start and finish the general theory of relativity.

Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

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.

The most common scientific explanation of how our universe came to be, is the Big Bang Theory. Around 13. 8 billion years ago there was no sign of anything apart from darkness. Until astronomer Edwin Hubble made a remarkable discovery about how the universe was created. Edwin Hubble hypothesised the matter and energy in the universe was initially condensed in a very small and infinitely hot mass. A huge explosion, known as the Big Bang, then sent matter and energy expanding in all directions (Howell, n.d.).

The idea that the universe had an origin was a result of the discovery of the expansionary universe.[vi] The theoretical groundwork for the expansionary universe theory was conceived, ironically, by Albert Einstein (a firm believer in the infinite and unchanging universe) in his work concerning relativity.[vii] The expansionary universe theory was later confirmed by Edwin Hubble in the 1920’s when he showed through careful observation of the

Neil deGrasse Tyson is a contemporary astrophysicist, cosmologist, author, and television host. He is best known for starring in numerous television shows explaining the universe in terms of physics. He states, “During our brief stay on planet Earth, we owe ourselves and our descendants the opportunity to explore — in part because it 's fun to do. But there 's a far nobler reason. The day our knowledge of the cosmos ceases to expand, we risk regressing to the childish view that the universe figuratively and literally revolves around us.” The universe has been a constant mystery and challenge to humankind. Humans wish to understand what is beyond their immediate environment. Cosmology is the study of the universe, more specifically, the origins, evolution, history, structure, and ultimate fate. In Greek, the term “cosmos” means universe, which is the very foundation of the study. Cosmology’s largest critic is Creationism; thus, science and religion battle it out to discover what is true and right in the world. The history of the universe extends past the beginning of humankind and the following philosophers, mathematicians, and astronomers will attempt to provide explanations of what is known today as the Great Unknown.

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.

Throughout the second chapter of Investigating Astronomy: A Conceptual View of the Universe, authors Timothy Slater and Roger

Dark matter is a very mysterious concept and scientist are not sure what it is . Dark matter is a substance that we do not know exactly what it is. Dark matter is something that is matter but is invisible to the best machines.Some of them are x-ray telescopes and dark matter is too cold for the machines to see. Can you believe that you can't see dark matter with our technology?

Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related.
