Because of the enclosed and finite nature of the universe, we cannot see "outside" of our own universe. Space and time began with the Where did the Big Bang happen? The Big Bang did not happen at a single point but instead was the appearance of space and time throughout the entire universe at once, according to The expansion of the universegradually slowed downas the matter in the universe pulled on itself via gravity. (Image credit: Getty) If other galaxies all seem to be rushing away from us, doesn't that place us at the center of the universe? No, because if we were to travel to a distant galaxy, it would seem that all surrounding galaxies were similarly rushing away. Think of the universe as a giant balloon. If you mark multiple points on the balloon, then blow it up, you would note t...

Ned Wright's Cosmology Tutorial Welcome to Ned Wright's Cosmology Tutorial or the Cosmology and art New on the tutorial: • A • A • A cool • A Cosmology is the study of the origin, current state, and future of our Universe. This field has been revolutionized by many discoveries made during the past century. My cosmology tutorial is an attempt to summarize these discoveries. It will be "under construction" for the foreseeable future as new discoveries are made. I will attempt to keep these pages up-to-date as a resource for the cosmology courses I teach at UCLA. The tutorial is completely non-commercial, but Astronomy and cosmology are very much mathematical sciences, but I have attempted to avoid higher math in these pages. I do use high school algebra and geometry - courses required for admission to UCLA - but I have also included some animations [ In addition to the Slides for recent talks: • th Faculty Research Lecture at UCLA, 28 Oct 2008. • • • • • • • Lectures at the International Summer Institute on Particle physics, Astrophysics and Cosmology, Hangzhou China, 2005 August • • • • • • • • • The News of the Universe JWST and High Redshift Galaxies 12 Dec 2022 - • et al. reports on 4 galaxies with redshift z > 10 in a well-studied sky field.

A modern colorized version of the engraving. Abrahamic Judaism and Christianity Main article: Biblical cosmology Biblical cosmology Main article: Genesis creation narrative The universe of the ancient Israelites was made up of a flat disc-shaped earth floating on water, heaven above, underworld below. Humans inhabited earth during life and the underworld after death, and the underworld was morally neutral; only in Hellenistic times (after c.330 BC) did Jews begin to adopt the Greek idea that it would be a place of punishment for misdeeds, and that the righteous would enjoy an afterlife in heaven. In this period too the older three-level cosmology was widely replaced by the Greek concept of a spherical earth suspended in space at the centre of a number of concentric heavens. Ex nihilo See also: The belief that God created matter is called creatio ex nihilo. It is the accepted orthodoxy of most denominations of Judaism and Christianity. Most denominations of Christianity and Judaism believe that a single, uncreated God was responsible for the creation of the cosmos. Islam Main articles: Islamic cosmology and Sufi cosmology Map of the world according to Zakariya al-Qazwini. The world carried by a fish, a bull and an angel. Islam teaches that God created the universe, including Earth’s physical environment and human beings. The highest goal is to visualize the cosmos as a book of symbols for meditation and contemplation for spiritual upliftment or as a prison from which the hu...

Norse cosmology divided the universe into nine realms. The center of the universe was the great world-tree Yggdrasil and the nine realms either spread out from the tree or existed in levels stretching from the roots down and, marginally, side-to-side. Earlier Norse works (known as Eddic and Skaldic poetry) assume a knowledge of the cosmology and do not bother much with descriptions of locations or, in some cases, even specifics of what the realms were like and, because of this – and the fact that Norse The Public Domain Review (Public Domain) Norse religious belief was characterized by the concept of síður (meaning “custom” or “habit”) in that it was fully integrated into the lives of the people. One would not attend service in anything like a church but would observe worship of the gods in one's own home, in a clearing in the woods, or in some sacred place of chthonic power. Even though there is evidence that temples to the gods existed, there is no record of what services or rituals performed there were like. The original nine realms of the Norse universe were probably: • Asgard – Realm of the Aesir • Alfheim – Realm of the Bright Elves • Jotunheim – Realm of the Giants • • Muspelheim/Muspell – A fire-giant or the forces of chaos or their realm • Nidavellir – Realm of the Dwarves • Niflheim – Realm of Ice and Mist possibly with lower realm of Niflhel • Svartalfheim – Realm of the Black Elves • Vanaheim – Realm of the Vanir After Snorri's work, the nine realms changed as ...

Cosmology Cosmology is the study of the origin, structure and evolution of the universe. The origins of cosmology predate the human written record. The earliest civilizations constructed elaborate myths and folk tales to explain the wanderings of the sun, moon, and stars through the heavens. Ancient Egyptians tied their religious beliefs to celestial objects and Ancient Greek and Roman philosophers debated the composition and shape of the ’s model of an Earth-centered Cosmos composed of concentric crystalline spheres dominated the Western intellectual tradition. Polish astronomer Nicolaus Copernicus ’s (1473 –1543) reassertion of the once discarded heliocentric (sun-centered) theory sparked a revival of cosmological thought and work among the astronomers of the time. The advances in empiricism during the early part of the Scientific Revolution, embraced and embodied in the careful observations of Danish astronomer –1601), found full expression in the mathematical genius of the German astronomer –1630) whose laws of planetary motion swept away the need for the errant but practically useful Ptolemaic models. Finally, the patient observations of the Italian astronomer and physicist English physicist and mathematician ’s (1642 –1727), important Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) quantified the laws of motion and gravity and thereby enabled cosmologists to envision a clockwork-like universe governed by knowable and testa...

Cosmology (the study of the physical universe) is a science that, due to both theoretical and observational developments, has made enormous strides in the past 100 years. It began as a branch of theoretical physics through Einstein’s 1917 static model of the universe (Einstein 1917) and was developed in its early days particularly through the work of Lemaître (1927). [ The uniqueness of the Universe: there exists only one universe, so there is nothing else similar to compare it with, and the idea of “Laws of the universe” hardly makes sense. This means it is the historical science par excellence: it deals with only one unique object that is the only member of its class that exists physically; indeed there is no non-trivial class of such objects (except in theoreticians’ minds) precisely for this reason. This issue will recur throughout this discussion. The second is Cosmology deals with the physical situation that is the context in the large for human existence: the universe has such a nature that our life is possible. This means that although it is a physical science, it is of particular importance in terms of its implications for human life. This leads to important issues about the explanatory scope of cosmology, which we return to at the end. 1. Cosmology’s Standard Model Physical cosmology has achieved a consensus Standard Model (SM), based on extending the local physics governing gravity and the other forces to describe the overall structure of the universe and its ev...
