The Big Bang Theory and the Expansion of the Universe

First, NASA furnishes a fabulous tutorial about the big bang theory and the evolution of the universe (1). Visitors can discover the foundation of the big bang theory, the observational tests, and the limitations and extensions of the theory. The second website, developed by Maxine Phaisalakani at the University of Toronto, introduces in a slide show presentation research that led to the discovery of the expansion of the universe (2). The site addresses many astronomical concepts including the big bang theory, dark matter, and the Doppler Effect. Next, The Online Journey Through Astronomy offers educational materials about studies leading to the discoveries of distant galaxies and the expansion of the universe (3). The website supplies two short animations illustrating the formation of the universe. The fourth site, created by PhysicalGeography.net, provides an online chapter about the past, present, and future of the universe (4). Students and educators can find links to a useful glossary and a list of additional readings. Next, PBS presents a timeline of the universe from the Big Bang to the future (5). This interactive website offers concise introductions to many of the key developments of the universe including the formation of elements, the earliest life forms, and the dark era. At the next site, the physicist, Patricia Schwarz, presents numerous animations, illustrations, and text dealing with the Big Bang Theory (6). Users can learn about the observations and knowledge that provide the framework for the theory. Next, Meta Research discusses hypotheses and assumptions about the big bang theory and the expansion of the universe (7). Visitors can find out why some scientists have qualms with the theorized phenomenon. Lastly, CNN provides an article about a group of Australian scientists' findings of a new string of galaxies that could challenge the big bang theory (8). Visitors can learn how scientists use computer simulation models to test astronomical theories.
