Physical Cosmology

The Beginning of Time In his blog titled “Huck, Jim, and Cosmology,” Joe Bauman effectively disarms his reader by using characters in Mark Twain’s The Adventures of Huckleberry Finn to introduce one of the liveliest areas in the discourse between science and religion - the paradoxical debate regarding how the universe came into existence. Bauman achieves this by employing an informative but neutral tone, detached diction, and common ground to place his reader on the level of an objective scholar...

Masks of the Universe: Cosmologies Since the Beginning of Time

Weekly Response This week Professor Wil van Breugel’s lecture was on “Masks of the Universe: Cosmologies Since the Beginning of Time”. He discussed how humans viewed The Universe, The Maya Cosmology, and The End of Time in 2012. Breugel explained how we see the universe through magic then mythic then finally scientific. Which I agree on because we do see the universe magically, imagining it as a place that is endless, mythically by believing that there are aliens or a higher being, and scientifically...

big band theory

Theory The big bang is a theory which describes how our universe started . Many discoveries in physics and astronomy tell us that our universe in fact had a beginning .This theory became the most widely accepted theory that has come to dominate cosmology .(1:1),(3:1) 2. The beginning of the universe According to the big bang our universe came into existence as a “singularity” about 13.7 billion years ago , but what is singularity? Singularities are zones which are thought to exist at the core...

Dark Energy

way to find out. | | | | The SuperNova/Acceleration Probe, SNAP, is a satellite designed to study dark energy through the discovery and precision measurement of thousands of distant supernovae. | | | | In a paper to be published in Physical Review Letters, physicists Eric Linder of Berkeley Lab and Robert Caldwell of Dartmouth show that physics models of dark energy can be separated into distinct scenarios, which could be used to rule out Einstein's cosmological constant and explain...

From the Large Scale Universe to the Milky Way

From the Large-Scale Universe to the Milky Way Paper SCI/ 151 August 4, 2014 Ellis Hodgdon Cosmology is the study of universe as a whole and the foundation of modern cosmology is that at one point in the past all the universe existed in one area. The Big Bang Theory was created to understand and explain how the universe came to be formed. According to the Big Bang Theory about 15 million years ago there was a giant explosion that pushed all matter in space outward and...

Astronomy Paper

Theory Phys 1070- Astronomy Topical Essay Motivated by the M-theory, space-time ‘branes’ and extra-dimensions, scientists Paul J. Steinhardt and Neil Turok introduce a tantalizing alternative to the prevailing standard Big Bang-Inflation model of cosmology. Traditionally, the Big Bang-Inflation model features an explosive epoch 15 billion years ago when time and space sprung into existence followed by a fraction of a second of superluminal expansion. Lacking adequate competition, the popular prototype...

Stephen Hawking

PhD in cosmology. Hawking's career has focused upon the cosmic entities known as black holes, and has extended to specialized areas such as quantum gravity, particle physics, and supersymmetry. A field of study that Stephen Hawking is known for is cosmology. Cosmology is the metaphysical study of the origin and nature of the universe. A brief synopsis of Hawking indicates that, according to Hawking, "there is 'no place for a creator', that God does not exist." In his quantum cosmology, he indicates...

Socialization of Child

theory at that time. And his contribution to society resulted from his personal conviction. Another remarkable example is Stephen William Hawking, who can not be well socialized due to his physical disability. Despite his loneliness and isolation, Stephen William Hawking contribute a lot in theoretical cosmology and quantum gravity. And it is reasonable to owe his achievement to his strong will, his pursuit for knowledge, and his intelligence. Finally, I disagree with the speaker's claim that...

Life Cycle of a Star (Gcse Level)

Big Bang cosmology require that redshifts be calculated using general relativity.[3] Special relativistic, gravitational, and cosmological redshifts can be understood under the umbrella of frame transformation laws. There exist other physical processes that can lead to a shift in the frequency of electromagnetic radiation, including scattering and optical effects; however, the resulting changes are distinguishable from true redshift and not generally referred as such (see section on physical optics...
